That first video looked like desync, which is kind of surprising on that setup since like I said I've been using those same motor/esc's on 3S with 6x4.5 props and no problems - and descync usually happens at higher power demands. But I also changed a few settings on my ESCS (I bumped the PWM rate to high to get rid of the high pitched squeal and I raised the timing to mid-high (default is mid)
So you may want to give that a try...
The jittering at start doesn't concern me quite as much - have you calibrated your ESC yet? You may just be starting with too low of a setting for that motor to run smoothly. Most brushless motors will stutter like that at very very low settings.
@ttprigg - I was thinking it could be a windshield...but it just doesn't look right any way I try to hold it on there. Maybe it was meant as a windshield but got abandoned.
I finally got mine out today and it flew great! My landings weren't very good but it handled them with grace and only took minimal damage. Few scuffs on the wings, and the wing slot is a bit longer now
Also knocked my wheel pants loose, but a few drops of hot glue and they'll be good as new.
The only major issue I had was my bamboo skewers have really wallowed out the holes in the body. The pod was wrapped in tape so it's holes have held up fine, but the whole pod wobbles around in there like crazy now because the body holes took such a beating. I think on my next one I may install the fake motor pieces - but instead of gluing them to the skewers as shown in the video I'll glue them to the chassis as doublers. I may also put a bit of old gift card / hotel room key behind them to make sure the skewers can't work loose. Other than that the plane is great but the motor mounts got so torn up I'm almost considering building a replacement plane already after just 3 battery packs. $1 worth of foam board is no big deal...but it was quite a bit of time to cut and build so I'd rather put a bit more effort into making it last a bit longer
Here's the maiden - I tried to keep it low close and slow so it would show up on camera better - by far my best maiden yet!
The DYS 1806 with a 6x4.5 prop and 2s 450mah nanotech pack ran great. I was afraid I'd be wanting 3s power but the 2s did perfect, I think 3s would be overpowered on this guy.
Glad I messed up and printed a second set of plans by mistake - after I finish my scout I'll definitely build another one of these!
And now I've got one more reason to replace the 1806 motors on my acro quad...I like these DYS motors on planes a lot better than on my quads
