DP Extra Canopy Fix??
Now the proud (?) owner of the ARC version....looking over everything, it seems the choice of how to fasten the canopy was the product of some hallucination regarding our tolerance for "screwing" with airplanes !!!!
SURELY -SOMEONE - with all these flying - has found a workable, and permanent solution to TWELVE screws on and off at every flying session???? PLEASE tell me yes....
And - ailerons are twisty things because they're 'ladders' with nothing to resist torsion, I think.
And - aileron servo mounting method seems to be where a LOT of flex could come from. Pretty mushy plate attachment method.
Having this plane here completely uncovered really gives me a chance to look into all the stuff from all the threads.
But it's a BIG hoss. Advertising this as an aerobat with a OS 1.60 FX is REALLY stretching it....but maybe not as bad as actually RECOMMENDING to use the 2-56 hardware! THAT is "insane".....

DP Extra canopy fix
Aerobob
I'm flying a DP Extra with a Taurus TS52 turning a Zinger Pro 22x8 prop. I have no problems with this set up, flys very well.
I don't remove my canopy when plugging in the wings. I installed a tongue on both sides of the fuselage through the large hole that the aileron leads pass through. The tongue goes into the wing root about a inch or so. I then drilled down from the top of the wing into the tongue (also about a half inch of lite ply under the top skin of the wing against the root rib) and installed a blind nut for a 6-32 bolt in the tongue. This also adds anti-rotation protection.
I'm also assembling a DP Extra for a friend. This one has diagonal ribs between the the aileron ribs. I didn't notice if mine has these ribs, keep forgeting to look. The advantage of the ARC is you can add balsa blocks in the wing and ailerons for robart hinge points. I used large pined hinges, nine in mine and seven in the new one (larger hinges).
Evert
P.S. If your ailerons dont have these diagonal ribs now will be a good time to add them before you cover.

Solution !!
Now THAT is a solution I think I can live with. LOVE it....very simple, effective, and Adds safety. GREAT idea, and thanks!
Regarding the diagonal pieces on the ailerons; that is EXACTLY what I had speculated would be needed to stiffen the things, and I'm definitely going to add them.....you don't know how much I appreciate your tip!!!
