You're nose wheel gear leg is too short. Wing AOA is too shallow for correct take off roll out. The plane shouldn't pitch downward wing striking the runway on take off. Good work with using heat shrink covering film in a non conventional way though. Also if the carbon that you referred to as "Rod" are actually Rods (solid carbon) you should probably use carbon tubes. Not sure if this is a language thing but I've noticed a lot of people refer to carbon tube as "rods"
Thanks for the advice! Yes I mean carbon fiber tubes they are indeed hollow. I believe the wing stricking on takeoff was because of the autopilot though because it was on stabilize mode and while I was flying it pulled to the left hard the whole time. The wings may have been asymmetrical but the autopilot should have done what it had to do to keep it level and given the fact that I was still able to turn right I believe it was an autopilot issue. Thanks for the comment!
@@letsMakeItFly If the auto pilot wasn't correct I have no doubt it had an effect in the erratic take off roll. However let's say for example that it was working correctly the elevator would still need to pitch the nose up to get the wing to have more effective lift. Being that the rear landing gear is basically the pivot point of rotation if the AOA of the wing is negative when the model is level on all gear the elevator is basically going to be fighting against that the farther aft the gear is from CG the more difficult for the elevator to overcome. If you extend the nose gear leg height enough that the wing is level with the ground/runway or slightly positive 1-2° perhaps autopilot or not you probably won't have to use any up elevator to get off the ground at first and lift off/rotation will happen at a lower speed and in a shorter distance. I mean I actually don't know from experience but I'm pretty sure that's what would happen.
@brianhutchinson7863 I agree with you, ill be extending the nose gear for the next flight. The wing strike was what I was referring to in my previous comment and the autopilot. Stay tuned, well see if your theory is correct. I'm hoping mid September ill have another video up with a much nicer wing! (and taller nose wheel haha!)
@@letsMakeItFly good luck and if you're interested check out a model called Melusine. It's a 3D printed FPV-able platform. It's very reasonably priced and if nothing else (you don't print, build and fly it) it would be a good example to study and perhaps gain insights with. That and you'd be supporting a cause similar to your own.
That takeoff was wild!
Sure was. Had me sweating!
I’ve been waiting to see your next video! 😊 looks phenomenal and worth the wait!
Hope you like it!
nice looking plane
Thank you! Wish it flew as good as it looks 😜
