I copy about the wood joke
It is indeed overkill for the task.
I tried to find what AUW should be but I didn't find "standard" wieght figures for this RC conversion. I saw most were in the 3-4 oz weight ? I am trying to build as light as possible and I hope it will be able to sustain the rigor of flying in a small gym. The lite kit is not heavy (tinybritelights) and adds 2 grams (.07 ounce).
I will use balsarite and coverlite to cover the plane.
