I thought my wings were painted on the wrong side when I first opened the wing but they weren't. The servo is on the top of the wing and is covered by the Fuse when installed, so the arm for the flap is on top of the wing. Felt kind of stupid when I figured that out... Are you just painting over the already painted covering? That paint seems to come pretty easily. Good luck on the bash.
Right now I'm pondering how much of the sheeting to remove around the retract servo bay. Sierra's retract is a little wider than the box built into the wing and to just sand it out to make the retract fit would pretty much remove any strength it might have. Love this thread!
