After flying my Flitetest spitfire and my BF-109 (basically the same fuselage), I found my front wingbox getting really weak and started tearing out. So I repaired it multiple times with hot glue but it kept getting weak.
So I designed a reinforced wingbox that easily mounts in place of the foam wing supports. Built out of 1/8in birch plywood it should be strong without adding to much weight.
It works great and you can still access the power pod. Now there is no reason to cut a whole new fuselage when your wingbox weakens. I have created an easy to follow how to video and the parts are available in the Attitude RC store Now!
