I have a Holy Smoke Delta that I'm converting from aileron/elevator to elevons. The roll rate is slow with the stock ailerons and they entered a flutter condition due to the sloppy cable/guide tubes. The hinges started to go away but I got it down OK. I'm planning on the using 1/8" "lite ply" as before and add a bit of feathered balsa veneer near the elevons hinge point to make it a tad thicker than the T.E. of the wing. There will be two used Hitec HS-5985 MG's (172 oz/in. and zero backlash) in the wing moved aft (about where seen) to move the CG more to the rear. The elevon will run the full wing length and cut/separated at center.

My question is, should I run the elevons full width or cut the taper as seen? Is there an aerodynamic reason for the taper at the wing tips like tip stall?






PS I'ts getting new cooler covering too.
