Thanx for all your input guys. 😊 There are many things that so far just dont make sense to me with this kit. Just look at the picture. The trailing edge has been sanded down to match the curvature of the wing but when i lay the ailerons on to the wing there is a huge difference in thickness. I just dont get it😣 this is my first core wing kit and i have never experienced this with my previous rib winges.
