3. 0:10All right, DIY airplane MarkV video part
4. 0:13number two. So, a lot of things have
5. 0:15changed since that last video.
6. 0:23[Music]
7. 0:35[Music]
8. 0:41I say I'm feeling pretty good about
9. 0:43this. The wings are on. They don't feel
10. 0:44too heavy right now. It's 14 lbs on each
11. 0:46side. I'm really only expecting to maybe
12. 0:48add another 8 lb to each wing, and
13. 0:50that's being pretty generous. So, if I
14. 0:52come out with that, I'll be really,
15. 0:53really well set as far as the all the
16. 0:55weight of the airframe.
17. 0:58[Music]
18. 1:16Wings are sanded. Everything's finished.
19. 1:18We're attaching the vinyl covering. And
20. 1:21this is highly unorthodox, but that's
21. 1:24why I kind of like experimental
22. 1:25aviation. And that's kind of also why
23. 1:27I'm definitely reinforcing and sticking
24. 1:28to the bit that I'm not releasing plans
25. 1:30for this because this is definitely
26. 1:32interesting. This could potentially be
27. 1:35fairly reliable wings for maybe like 2
28. 1:36or 3 years or they could be completely
29. 1:38disastrous if you leave out in the sun
30. 1:39and then you know it's it's all over in
31. 1:41a couple days.
32. 1:43This is fun. I like this because like I
33. 1:45don't have a lot of money wrapped up in
34. 1:46this. It's just really the aluminum
35. 1:47which is the most expensive part and
36. 1:48maybe the hotwired foam. So yeah,
37. 1:50experimental aviation. Yeah. while that
38. 1:52we're in the Ultralite class.
39. 1:55[Music]
40. 1:58All right, now the vinyl's down. I'm
41. 2:00actually going to slightly melt the foam
42. 2:02and the vinyl and try to fuse the
43. 2:04adhesives together as much as possible.
44. 2:06I think this is really going to keep
45. 2:07this thing sep stuck down. I actually
46. 2:09made a test piece a year ago and it's
47. 2:11actually still very hard to kind of
48. 2:13separate this kind of method from each
49. 2:15other. So, this is working out pretty
50. 2:16well. Well, it definitely doesn't look
51. 2:17good, but I'm hoping it stays attached
52. 2:20cuz like I'm more concerned about cheap
53. 2:22and effective versus, you know, a
54. 2:23high-speed finish. This is not a
55. 2:25high-speed finish. This is not a
56. 2:26high-speed airplane.
57. 2:30Curious about this vinyl covering, too.
58. 2:32How much it'll weigh. So, let's get a
59. 2:33weight of the wing first. 198 lb. That's
60. 2:36actually not bad at all. This is a lot
61. 2:37lighter than all my previous wings.
62. 2:39Hopefully, the vinyl covering I'm only
63. 2:40maybe expecting like 3 lb per panel. So,
64. 2:43hopefully a flying weight of 23 lbs per
65. 2:44panel. I will definitely be on track to
66. 2:46be making my light ultra light.
67. 2:51Uh 21 lb even. So 20 lb. So it looks
68. 2:55like we're only add maybe around like
69. 2:56maybe a pound a pound and a quarter so
70. 2:58far. That's just not that bad in just
71. 2:59vinyl covering. So yeah, these will be
72. 3:01very light wings when I'm done. All
73. 3:04right. Now we got the other other side
74. 3:06covered. It looks like it's 22 lbs on
75. 3:08the scale. This is officially the
76. 3:10lightest completed wing I've ever made
77. 3:11for one of my crappy homemade airplanes.
78. 3:13All right, let's do the other one and
79. 3:14then we can move on with tests. These
80. 3:17are the same sandbags used last time I
81. 3:18stress test my third airplane design.
82. 3:25[Music]
83. 3:34[Music]
84. 3:36It is now time for the wing loading test
85. 3:39cuz I did a bunch of TL engineing which
86. 3:42is that looks about right which is
87. 3:43horrible for airplane design but luckily
88. 3:45I have an airplane building experience
89. 3:46and I had some actual arrow friends come
90. 3:48and look at this thing. Plus I've
91. 3:49actually used basic components that were
92. 3:51used off of other traditional ultral
93. 3:52lights with the same weight class. So,
94. 3:54this should pass with flying colors cuz
95. 3:56everything is a lot lighter on mine than
96. 3:58what I'm using. But, we're going to
97. 3:59figure this out. Everything that's not
98. 4:00lifted weighs about 100 lb. Then I weigh
99. 4:03about 150 lbs to just say on the safe
100. 4:05side. So, that's 250 lb. So, if we get a
101. 4:07250 lb on the wing, that's 1g. So,
102. 4:10that's basic normal flying. If we double
103. 4:13that, we'll get the 2 G's. And that's
104. 4:15still okay. It's whatever. It's good
105. 4:16enough. 750 3 G's. 3GS is actually kind
106. 4:20of a lot for an ultra that flies on a
107. 4:21calm evening. So, we'll probably stop
108. 4:23somewhere around here. We may go a
109. 4:24little beyond 750 depending on how much
110. 4:25sandbags we have. I don't think we'll
111. 4:27get to quite to 4G cuz that's 1,000 lbs
112. 4:28and that's a lot of weight. Also, we're
113. 4:31actually doing this a little bit
114. 4:32differently. This is sort of incorrect,
115. 4:33but I have a block here that we're
116. 4:34setting the airplane on cuz the only
117. 4:36thing that we're not really going to get
118. 4:37a good test on is the fuse lodge itself
119. 4:38cuz the members that hold the wings up,
120. 4:40they're going to be in compression
121. 4:41rather than tension. So, if I my
122. 4:44original plan was to cement it from the
123. 4:45ceiling. However, I couldn't really get
124. 4:46stuff up there to do that. So, we're
125. 4:48going to have to do it this way and just
126. 4:49stress test the spars, the wing struts,
127. 4:52and the center part of the fuselage. We
128. 4:53just won't be able to actually test the
129. 4:55strength of this right here, which is
130. 4:56the center part of the fuselage. Cuz uh
131. 4:58in normal flight, it would actually be
132. 5:00pulling itself apart rather than being
133. 5:01compressed. All right, let's begin the
134. 5:03test.
135. 5:10[Music]
136. 5:14All right. Well, that's one G. That's
137. 5:15very obvious. is going to survive that.
138. 5:17Let's go to 2G's.
139. 5:19[Music]
140. 5:25This is 2G's. This is probably what the
141. 5:26most I'll ever really logistically
142. 5:28loaded in flight, too. I'm looking for
143. 5:29compression here, too, cuz this is
144. 5:30loaded incorrectly. Like, this thing is
145. 5:32being squished right now.
146. 5:33Typically, it will be being pulled apart
147. 5:35in flight. So, this is a little
148. 5:36different than where how it would
149. 5:38actually be loaded. Tightening down the
150. 5:39wing, and it's hardly deformed at all.
151. 5:42No real flex in that at all. So, we're
152. 5:44going to keep going.
153. 5:47[Music]
154. 5:55It's getting heavy now. So, we are at
155. 5:57900 lb. So, we're not quite at four, but
156. 5:59we're over three. This is good enough
157. 6:00for me. I'm happy. I want to measure
158. 6:02deflection and then take the sandbags
159. 6:04off and let's see what we get.
160. 6:07Okay, then. Now, it's going to support
161. 6:09full weight.
162. 6:11That's a lot of weight for some
163. 6:13styrofoam and some aluminum. I see some
164. 6:15stuff going on in here. This looks like
165. 6:17bowing a little bit.
166. 6:18Look, it is bowing. That's why this is
167. 6:20like
168. 6:20Yeah, that's why that's flexed out. This
169. 6:21is This is in compression, but luckily
170. 6:23it's not doesn't look permanent. So,
171. 6:24when I take this off, it should just go
172. 6:25back to the way it was,
173. 6:26but the windscreen is being pushed out.
174. 6:28All right, I'll just take everything
175. 6:29off.
176. 6:32Well, the wing looks back to normal.
177. 6:34Just covered in a little bit of sand.
178. 6:35Actually, that was a good test of the
179. 6:37foam itself, too, because there's
180. 6:38actually no ribs or any sort of wood in
181. 6:40here. And all that force was localized
182. 6:42like within the center of the foam,
183. 6:44where the spars are actually out here,
184. 6:46but the sandbag was here. So, all that
185. 6:47was actually being sucked straight into
186. 6:48the foam. So, that's really impressive
187. 6:50that with that pattern cut out in it,
188. 6:52the truss shape, it was still able to
189. 6:54survive that very easily and not buckle
190. 6:55or crack or rip right out through the
191. 6:57bottom. So, we're definitely more than
192. 6:59good to go cuz on normal flight when
193. 7:01it's stressed out, it will be dispersed
194. 7:02almost evenly across the surface. It
195. 7:04really depends on your angle of attack,
196. 7:05but that's just more airplane complexity
197. 7:06stuff there. But I'm very, very
198. 7:08satisfied with what I see so far. Don't
199. 7:10get any ideas about doing this yourself
200. 7:12yet. I have no idea how long this is
201. 7:13actually going to last. This is a very,
202. 7:14very big experiment.
203. 7:16Lurking around the comments of the
204. 7:18internet, it looks like I actually found
205. 7:19some more information about this engine.
206. 7:20It It turns out someone actually got
207. 7:22like communication from Vitarazzi, which
208. 7:23is the manufacturer of this motor. And
209. 7:25it turns out this PSRU or prop speed
210. 7:27reduction unit does not like being
211. 7:29pulled on such as my airplane because
212. 7:31it's in a tractor configuration. So,
213. 7:33unfortunately, this is not going to have
214. 7:35to work. So, I had to pull off and start
215. 7:36from scratch. Basically, it turns out I
216. 7:39actually have a friend Paul from Open
217. 7:40PBG. He's been working on a single
218. 7:42motor, electric pair motor, and I
219. 7:44thought, hm, that's kind of cool. Maybe
220. 7:47I should do electric again, especially
221. 7:48cuz, you know, things have advanced in
222. 7:49like the last 4 years since I did
223. 7:51electric ultralite. So, now we're going
224. 7:53to use something that's electric.
225. 7:57[Music]
226. 7:58[Applause]
227. 8:03I don't want to do much more than that
228. 8:04cuz that crappy motor mount. I installed
229. 8:07all the electronics and stuff and fire
230. 8:08up the motor. It does work. Nothing
231. 8:10exploded fortunately. But I did find out
232. 8:13I can fit the tiny propeller on the
233. 8:15really big motor. The reason why I'm not
234. 8:16using the propeller is I'm still waiting
235. 8:17on the motor mount. So I'm going to
236. 8:20check to make sure the amp meter works
237. 8:21and I'm going to put a small load on
238. 8:22this propeller. It's going to push the
239. 8:23air backwards moving the wrong
240. 8:25direction. But hey, at least I'll get to
241. 8:27see the meter do stuff and confirm
242. 8:28everything works before we go to the big
243. 8:30engine.
244. 8:33We're currently drawing 1 amp. 1 amp at
245. 8:3792 volts,
246. 8:40130 W. Oh, here's a cool thing, too.
247. 8:42Come over this side. One thing I did
248. 8:44just in case the uh let's say the
249. 8:46motor's running away.
250. 8:48Oh, no. Oh, no. I don't like this.
251. 8:52Pull it and it just it completely
252. 8:53disconnects the system. So, it's no
253. 8:55longer running. Now, however, you do not
254. 8:58want to get the spark idea of plugging
255. 9:00this thing back in cuz 92 volts without
256. 9:02a spark suppressor. Oo, it's going to
257. 9:05make a big spark. I got the motor mount.
258. 9:09Get some use out of that winch.
259. 9:12All right, here we go.
260. 9:15[Music]
261. 9:28That was full power. I can't even pull
262. 9:30it back. It sounds very smooth. I'm
263. 9:32actually very happy. It doesn't terrify
264. 9:34me. The funny thing is I didn't really
265. 9:35mention this, but when I was using the
266. 9:36old Moisture 185, this thing was like,
267. 9:39shake it. This is really smooth, crisp,
268. 9:41and clean with no caffeine.
269. 9:45[Music]
270. 10:12Heat. Heat.
271. 10:14[Music]
272. 10:26It's done a lot faster than any other
273. 10:28planes. Cotter pins are in. Basically,
274. 10:30it's 1 2 3 4 5 6 7 8 9 10. 10 bolts and
275. 10:35you're done. I don't really count the
276. 10:37fairing to, you know, close the wing
277. 10:39tips up. So, it's literally just 10
278. 10:40bolts. Put the pins in them and we're
279. 10:42good to go. I'm going to pre-flight it
280. 10:43because obviously this is the very first
281. 10:44time flying this and you should really
282. 10:46pre-flight any aircraft. But this one
283. 10:47needs a thorough inspection because it's
284. 10:48been trailered now. So I need to make
285. 10:49sure everything's set and then I'm going
286. 10:50to start the taxi test or the low low
287. 10:53altitude flying test. Probably just
288. 10:54applying it if it's too windy because uh
289. 10:57it doesn't have a so I literally have to
290. 10:58go for it to keep the wings from
291. 11:00touching the ground. All right, one last
292. 11:02thing. Don't forget the fat kit in case
293. 11:04I have a blowout because the propeller
294. 11:05comes back and smacks me in the face.
295. 11:08Clip. Clip this.
296. 11:11Yeah. Yep. Awesome.
297. 11:13All right. Batteries are locked. Time to
298. 11:15put on the aerodynamic bolt holder.
299. 11:17That's what I'm calling this. It just
300. 11:18weather veins and it should keep it from
301. 11:20spinning if I think this works the way I
302. 11:21think it's going to work. The thing with
303. 11:22this plane is has no ailerons. If this
304. 11:25was an aon airplane, if I start getting
305. 11:26too high off the ground, the wing starts
306. 11:27rolling, I just flatten it back down
307. 11:29with a baleron and just fly, you know,
308. 11:31adjacent like crabbing across the
309. 11:32runway. This is an avail. So, I if I get
310. 11:35to that stage, I'll probably have to
311. 11:36crack with water but gain more altitude
312. 11:37to keep the wings from touching the
313. 11:38ground. So, at that stage, I'm probably
314. 11:40flying. So, I'll either fly to the end
315. 11:42and put it back down, or if it's too
316. 11:43high, I just fly it and go around
317. 11:45planes. All right, we're ready to go.
318. 12:02Well, it flies.
319. 12:10[Music]
320. 12:17[Music]
321. 12:25I forgot how to steer the airplane. I'm
322. 12:26trying to move. I was like, "Oh, wait.
323. 12:28Yeah, rudder." It's always better to air
324. 12:29inside of a nose heavy airplane for the
325. 12:31first couple of flights, but I think I
326. 12:32could probably put a few pounds in the
327. 12:33tail. So, I'm going to put this in the
328. 12:35tail.
329. 12:36I was trying to make them just a little
330. 12:38bit nose heavy right off the get- go.
331. 12:41Nah, I won't fall off. I'll be way
332. 12:43different. I'll barely probably notice
333. 12:45this, but it's something. What I do is I
334. 12:47need a gun. So, when I'm flying, if the
335. 12:49plane is too tail heavy, I I look back,
336. 12:51I shoot the water bottle, the water
337. 12:52bottle empties out its fluids, and then
338. 12:54I become presume nose heaviness, and I
339. 12:55can continue flying.
340. 13:00[Music]
341. 13:02All right, y'all ready to see me fly?
342. 13:05Yeah.
343. 13:11[Music]
344. 13:16Heat.
345. 13:33[Music]
346. 13:51[Music]
347. 14:01Heat. Heat.
348. 14:04[Music]
349. 14:23Heat.
350. 14:27[Music]
351. 14:51Heat.
352. 15:14[Music]
353. 15:18was at full power the entire time. This
354. 15:20thing does not make any thrust once it
355. 15:23starts going kind of fast. I was like
356. 15:25Max was like just flying the version. I
357. 15:27was like going round and round. Back on
358. 15:29the ground. Get me on the ground. I want
359. 15:30to be on the ground. Okay, we're back
360. 15:33from the first flight. Um,
361. 15:35yeah, that did not go as well as I
362. 15:38wanted it to. The pitch speed of the
363. 15:39propeller was a little bit too flat,
364. 15:41meaning I couldn't really accelerate
365. 15:42even with the throttle pegged at full
366. 15:43power. The propeller was basically just
367. 15:45turning as fast as it could possibly go.
368. 15:46However, the oncoming air speed was too
369. 15:48quick. Also, one thing that I found
370. 15:49really interesting because I've never
371. 15:51really flown a aonless airplane, which
372. 15:53is this is basically a two axis control
373. 15:55was the rudder is extremely sensitive in
374. 15:58like roll control as well. A lot better
375. 16:00than I thought it would be. Especially
376. 16:02like if you look at one of these tests
377. 16:03here, you'll notice that when I kicked
378. 16:05the rudder over, it rolled a lot and
379. 16:06that was actually just induced by the
380. 16:08coupling of the whole dihedral thing and
381. 16:10where the rudder is and so forth. So, it
382. 16:12actually flew very well and actually
383. 16:13satisfied my kind of requirements for
384. 16:15control. The second thing that I noticed
385. 16:17was the leading edge of the elevator,
386. 16:19which is this service here, was
387. 16:20fluttering a little bit. This made me
388. 16:22very, very, very nervous. I knew it
389. 16:24might have been a possibility. I just
390. 16:25didn't think it would happen at this
391. 16:26kind of sort of air speed, which is
392. 16:28around like 35ish miles an hour. So,
393. 16:30what was happening was I couldn't see it
394. 16:32during the taxi test cuz I was more
395. 16:34preoccupied and just flying down the
396. 16:35runway. Now, climbing away from that and
397. 16:37actually getting some time to kind of
398. 16:37pick up some speed, I noticed it was
399. 16:39probably fluttering maybe around 3 in
400. 16:41from center line of deviation. It's a
401. 16:44bit much for me. It makes me a little
402. 16:45bit nervous. So, I was like, "Okay, need
403. 16:46to slow down, fly it on the edge of sort
404. 16:48of the minimum kind of flyable speed I
405. 16:51could fly it at, and just slowly bring
406. 16:53it around and put it back down the
407. 16:54ground cuz we need to make some changes.
408. 16:58So, now that we know we need to change,
409. 16:59we're going to do it. The first thing
410. 17:00I'm going to do is lop off the old wing.
411. 17:02I'm just literally going to hot wire the
412. 17:04foam cap off, then add three feet onto
413. 17:06it." It's actually very simple because
414. 17:07the way I've designed this wing, since
415. 17:09it's just two aluminum bars, it's
416. 17:11typically it's like a ladder style
417. 17:13ultralight wing. So, I literally just
418. 17:14machined some spacers, slip the aluminum
419. 17:16tubes in, put some glue on top, and just
420. 17:19just literally add more vinyl, and then
421. 17:20the wing is done. That's it.
422. 17:24[Music]
423. 17:37I added a 3-ft extension onto the wing
424. 17:40panel, so it's it's got a higher aspect
425. 17:41ratio now, so it should fly better cuz
426. 17:42there's hardly any penalty for adding
427. 17:44any extra wing on except for extra wing
428. 17:46structure. But I did that by taking more
429. 17:48lumin tube and simply shoving it in. We
430. 17:50done a little bit more modifications. I
431. 17:51added the wheel to my tail skin because
432. 17:53I'm probably do more taxi testing this
433. 17:55time cuz I just hate dragging around.
434. 17:57When I actually fly though, I'm taking
435. 17:58that off cuz uh I like the brakes. And
436. 18:00by mean brakes, I mean dragging the tail
437. 18:02on the ground. We have a three-bladed
438. 18:03propeller now for better performance.
439. 18:04Propeller has more pitch because last
440. 18:06time we were flying a plane in first
441. 18:08gear. If you can kind of imagine this,
442. 18:09it's basically trying to ride a bicycle
443. 18:11at 30 mph in first gear. You got to
444. 18:14pedal really fast, but you're not really
445. 18:15making any extra speed. There's a little
446. 18:16resistance, but the motor is turning
447. 18:18very fast cuz I watched the amp draw go
448. 18:20way down. Also, it's worth noting I flew
449. 18:22on 11 kW of power. to put anything into
450. 18:25perspective because those are just
451. 18:26numbers. My first plane had 25 available
452. 18:28kilowatts of power and I probably flew
453. 18:30maybe around like 20ish of that. So,
454. 18:32it's pretty good that it flew on 11
455. 18:33kilowatts. It should be even less with
456. 18:35the increased wingspan. And with this
457. 18:37prop with more pitch, I should get more
458. 18:39kilowatts. And I put on the meter and I
459. 18:41can generate I think it's around 18 kW
460. 18:43now at full power. So, that's better.
461. 19:06We're all set. And my flight plan pretty
462. 19:07much is to fly. But we'll see if if it
463. 19:09feels really good, I'll probably just
464. 19:10continue to climb and we'll just fly
465. 19:11around. All right. All right. All right.
466. 19:13Well, it's not really quite that simple.
467. 19:15So, I did think about this ahead of time
468. 19:16of like how I want to specifically
469. 19:17handle a low-e, low performance
470. 19:19airplane. Cuz a lot of you guys have
471. 19:20pointed out you need to fly that thing
472. 19:22to 1,000 ft and then some so you can use
473. 19:24that rocket parachute. Well, yes, but
474. 19:27also kind of no. The weird thing about
475. 19:29my airplane is it operates like in such
476. 19:31a low performance category. It's like
477. 19:33simply it's below like 25 knots flying
478. 19:35and that's like flying fairly well too.
479. 19:36It's not the fault that specifically
480. 19:38kills you when you jump off a building.
481. 19:40It's the sudden deceleration. And
482. 19:42there's not a whole lot of energy or
483. 19:43potential energy that needs to be
484. 19:45absorbed somewhere. If I were to simply
485. 19:47have a complete structural failure like
486. 19:48below 50 ft, I probably give myself a
487. 19:5175% chance of survival. Maybe the rudder
488. 19:52falls off or some something
489. 19:54catastrophic. maybe even a full full
490. 19:56wing collapse, which is highly unlikely
491. 19:57in this case. 75% chance there of me
492. 20:00surviving that. Now, here comes the
493. 20:01issues like climbing from beyond like
494. 20:03100 ft to 1,000 ft. This puts me in a
495. 20:05very weird area because it's high enough
496. 20:09where I can get enough velocity to hit
497. 20:11the ground very hard and suddenly stop
498. 20:13and also probably scramble my brains.
499. 20:14Also low enough too that I have no time
500. 20:16to literally throw the hand toss
501. 20:17parachute, which probably needs a little
502. 20:18bit more than 500, maybe even 1,000 ft
503. 20:21to really successfully deploy. So, I
504. 20:23kind of give myself like brackets on how
505. 20:24I would survive. And this is all if the
506. 20:26plane does not climb very very quickly,
507. 20:28I'm going to stay kind of low cuz I'm
508. 20:29thinking if it doesn't climb super well,
509. 20:31I'll just stay low cuz I know it's safe
510. 20:32down here and I know I have a fairly
511. 20:34good chance of walking away cuz a lot of
512. 20:35guys are using this metric of like a
513. 20:36composite airplane or something that
514. 20:38flies at like 80 knots at like liftoff
515. 20:40speed. Anything below like 1,500,
516. 20:42assuming the plane has a ballistic
517. 20:44recovery system, which is a rocket
518. 20:45parachute or something similar to that,
519. 20:47you would have a very, very, very low
520. 20:49chance of surviving if anything were to
521. 20:50happen. And having altitude is your
522. 20:52friend specifically in this case because
523. 20:53it gives you more time to think. If you
524. 20:55were going to have like an engine out or
525. 20:56something like that, but a structural
526. 20:57failure, all the energyy's got to go
527. 20:59somewhere, it's probably not going to
528. 21:00end well for you. That's why I really
529. 21:02have a slightly different flight plan
530. 21:04planned for my ultralite. We should fly
531. 21:06now.

558. 24:31Toyota.
559. 24:35That flies really good. I am so happy
560. 24:39with that. Ooh. Cruises around like 80
561. 24:4390ish amps or so. flies at a nice
562. 24:45comfortable 30 mph. It is the dream
563. 24:48machine.
564. 24:57[Music]
565. 25:06Yeah, that was much better. Much, much
566. 25:09more satisfying. Perhaps the most
567. 25:11satisfying Ultlight I've ever designed
568. 25:12and built and flown. It still didn't
569. 25:14have as much power as I thought it
570. 25:15would. I think I need to advance the
571. 25:17pitch of the props a little bit more.
572. 25:18However, man, this thing flies great. I
573. 25:21wasn't really sweating at all. It was
574. 25:22more just like a nervous laughter flying
575. 25:24around like, "Oo, I'm flying and this is
576. 25:26great." So, obviously, I decided not to
577. 25:28climb very high because well, my climb
578. 25:29performance was anemic, so I couldn't
579. 25:31really climb out of that safe bracket
580. 25:32cuz within that bracket of time, I know
581. 25:34you need to get out of there very
582. 25:35quickly to be safe. So, I figured I'll
583. 25:37just fly it on low. I like to fly low
584. 25:38and slow anyways. And this is what this
585. 25:39airplane is designed to specifically do.
586. 25:41So anyways, it's a two axis design. A
587. 25:43lot of you guys keep freaking about
588. 25:44that. I noticed it's like yes, yes, yes,
589. 25:46aerons are great and all that. However,
590. 25:48if you look back in the days of like the
591. 25:501970s and early 80s, a lot of ultral
592. 25:52lights were two axis. Just name a few
593. 25:54designs, the Sky Pup and the Wheat
594. 25:56Hopper, and they were both incredible
595. 25:57airplanes, and I haven't really heard
596. 25:58anything bad about those. So, I knew it
597. 26:00would probably be okay. And well, it's
598. 26:02okay. It flies all right. All right, so
599. 26:04future mods. There are a few more things
600. 26:06I want to clean up such as like putting
601. 26:07aerodynamic struts on there and sealing
602. 26:09the gaps and stuff, but that stuff costs
603. 26:11money and this project was a very
604. 26:13expensive project considering all the
605. 26:14batteries and electric motors and stuff.
606. 26:16That's why I really would like to say
607. 26:17thanks to Kico for sponsoring this video
608. 26:19and making this possible. So, a lot of
609. 26:21you guys asked me, Peter, how'd you get
610. 26:23so good at making things? Basically,
611. 26:24when I was a kid, I tinkered around a
612. 26:27lot.
613. 26:29Triccopter thingy. This is the veto I've
614. 26:32been working on, and that's why I'm very
615. 26:34happy to have Kiwi Co sponsoring this
616. 26:36video.
617. 26:38KiwiCo makes these amazing crates
618. 26:40tailored around science, technology,
619. 26:41engineering, arts, and the maths,
620. 26:43otherwise known as steam. These crates
621. 26:44are awesome. Everything that you need is
622. 26:46inside the box, so you don't have to run
623. 26:47to the store. I was actually impressed
624. 26:48because they even gave me the A battery
625. 26:50to complete this robot. The cool thing
626. 26:51about Kiwiico is they make all sorts of
627. 26:53different crates depending on your age
628. 26:55group and the subject you want to cover.
629. 26:56Once you complete your projects, they
630. 26:58even have supplemental information in
631. 26:59the books to modify your project and to
632. 27:01learn even more or make your robot fly.
633. 27:04[Applause]
634. 27:06Fireworks not included. That's why
635. 27:08Tinker Crate and Kiwi Co is a great
636. 27:10learning opportunity if you got kids or
637. 27:11if you want to experiment or learn
638. 27:13something new or just build around some
639. 27:15stuff. These are actually great
640. 27:16supplemental information you can give to
641. 27:17your kids or yourself if you just want
642. 27:19to learn something at home.
643. 27:22So, these products are like kind of
644. 27:23great hands-on experiences cuz, you
645. 27:24know, at the end of the day, I learned
646. 27:25best by tinkering and just getting my
647. 27:27hands involved with this stuff. If
648. 27:28you're looking a great way to get
649. 27:29started with something, try these things
650. 27:30out. I'm impressed with these, and they
651. 27:32have all sorts of cool ones, and
652. 27:33hopefully they actually send me a few
653. 27:34more to play with. These products are a
654. 27:36lot like things I work on.
655. 27:39Everything's included in the box,
656. 27:40though, and there's a lot less fire
657. 27:42involved in all sorts of dangerous
658. 27:43stuff. They got to be kid safe, you
659. 27:45know. All right, so these things are
660. 27:47really cool. If you check out the link

667. 27:58man. I'm so happy with it. It flies so
668. 28:01great. If you guys want to see more
669. 28:02flight footage of this and more raw
670. 28:04stuff ahead of time, check out Sam's
671. 28:05channel. He's been kind of doing his own
672. 28:07thing lately, especially if you want to
673. 28:08see early stuff because like you can see
674. 28:10this thing flying like weeks in advance.
675. 28:12But anyways, thank you guys for
676. 28:14watching. Enjoy some more of the smooth
677. 28:15B-roll and I'll see you next time.
