I am new in electric fly, in glow I have but of 30 years of experience, I am going to cut in deprón the Diablo 3D Batic, in the planes say that the horizontal surface, the plane of tail and the elevator, can be of 3 or 6mm, that is the best thing?
Sorry I do not speak ingles well.
Thank you.

6mm is better for durability and 3mm is better for light weight setups.

I made one all out of 6mm, flew great untill I hit the light pole.
