RE: ??? My first build what tools do I need??
The Sig 1/4 scale Cub is a great airplane, but not the best choice for a first build. It is what's known as a "Builder's Kit"
For example, the frame pieces for the Fin and Stab are not die-cut - they are just printed on a piece of balsa and you'll need to cut them out yourself.
So a scroll saw would be very handy. If that's too pricey, at least get a coping saw to do most of the cutting with
