Got a little bit of free time, so I finished her up. She's got (8) 1407-3500kv motors, (8) 3052x3 propellers (It'swhat i had), (8) 20a esc's, (4) 9g metal servos, a 5V BEC, and will run on a 2s 450mah and 3s 2700mah (for now) batteries. I'll paint her the ugly gray after her maiden. Not sure when I will get time to fly again, but hopefully soon.

Got her out this evening. She did fly, just not very good. She was definitely tail heavy, and had a big pitch to the right. I believe the pitch was due to a bent wing. Used all the trim I had, but only wanted to turn (very unstable) in one direction. Couldn't keep her stable at lower speeds, and then the ground came up and pulled me out of the sky. I definitely want to revist this, maybe a good build-uary project. Will post a video in the next day or two. Pry a couple of adult words I need to edit out.

Sorry to hear it crashed, it was a really nice plane!

bummer! she was a beauty, even if she didn't quite fly right. I hope you get to build it again.

I am very glad you had yours flying! Sorry it was so throttle dependent for success. Any parting thoughts for me on the design, or plans, or for others or yourself next time?

I really like the design. Just two things come to mind to change. First, push the cg a little more foward. Like I said on discord, I really think it was a bit tail heavy. Over a minute of edited out footage (bad or blurry) would of shown that more. The other would be extend the bottom of the wing all the way out with a spar from end to end. Due the peeling of the paper on the top of the wing (which is needed), the ends of the wings very floppy and weak. I think this might of caused the pitching to the right. Both very easy fixes (if my guesses are right).

With all new plane designs there will be some bugs to work out. Now that I have all the wiring done, and built it once already, the rebuild should be easy peezy. I'm thinking build-uary time. Gonna keep all eight motors going, cause that's my favorite part.

Think of it this way Rick; you had a pretty good, scale, flight! There're reasons Howard only attempted to fly that airplane once.
Lol. True. But I haven't given up on it yet. Since the hardest part of the build is still fine (electronics), I have it on my build-uary list for February of next year. I hope with a few slight modifications I can get it to fly better.
....... or crash bigger. 🤷‍♂️😁

P.S. I Think I got more altitude than Howard.

Can we get a Sound sample of V1 with all 8 motors singing? 🙏
