RE: Wood filler and balsa
Hey, that's funny. I didn't notice that this was for a Wonder at first. I'm currently covering my Wonder myself. I went with a Magnum 15xls and Hitec HS-82MG servos on aileron/elevator and HS-81 on throttle. BTW, I thin the Elmer's with water to help make it easier to spread. Good luck with your Wonder!
