It would be better with no dihedral if you wanted a plane that could roll well. this one can do a roll if you give it a lot of throttle, but not well. It is very stable and docile like this now that I got it flying ok.
hi 2:19 WHY is part of the vert-stab missing.! this design results in elevons that have a wonky shape.! the Distribution of Mass (dom) Determines the locations of the cg and the c-m. c-m is center of mass. it is up to YOU to Distribute the mass of the power and control components Optimally. said another way, it is the opposite of smart to locate the mass of the elevon servos aft of the cg. you may realize that stability could be increased, if some mass -- say, the battery -- were located below the wing. it should be understood that the term 'tail-heaviness' is used, colloquially, in place of saying 'mis-located cg'. tail-heaviness occurs in the dom. in this case, the aft-located mass of the elevon servos is causing Permanent tail-heaviness in the dom. d
oh boy. A lot to get to here. So originally, the nutball has that shape of vert-stab to make room for the elevator to move to it's full throw. I just traced the orig vert-stab, and cut the elevator in 2 to make it an elevon setup. I was going for as few changes from a typical nutball design as possible, but trying to make it sub 250g. I thought I might possibly add a rudder later, as well. The servos are behind the cg only because I didn't have control rods laying around that were longer. Also, having the servos in front of the cg doesn't help significantly with this plane. I have 2 traditional elevator and rudder versions of this, one with servos in the same place, one with them very far forward, and they fly pretty much identically, I just have the battery a bit further forward on one than the other to compensate. The battery underneath would help, but the next step with this plane is to paint the entire bottom with a smiley face or a target, and I don't want anything at all on the bottom. I got it flying just fine with this setup with adjustments to the elevon reflex. It wasn't actually tail heavy. The DOM didn't keep it from flying well. It was bad setup of the elevons to blame (too much reflex).
I hear the pilot is a very handsome dude
It hasn't helped the views on this channel though...lol
@@lienmeat start showing your face on camera then 😋
@@lienmeatjust subscribed, love chill vibes mate
@@biko9824 great, let me know if there's anything you'd enjoy seeing I might be able to do!
Maybe YOU need to make a Cameo!! ; )
Great video brother. Question. How many airplanes do you have stuck up in the top of those Magnetic tree's that surround that flying field.
@@gisall8205 Lol thanks! I've crashed about 6x into the trees here but always managed to get the plane back eventually with some work and some luck.
I had a couple of these!! I have not had success with elevons with dihedral, they dont seem to get along?? lol
