One of my favorite planes. There are very few things that you need to change.
If you build it as a tail dragger (recommended) discard the tail wheel wire
supplied and use a Sullivan. The supplied wire WILL break.

You can use dual aileron servos mounted out in the wing. I did
this with mine but the stock aileron arrangement works well.

Other than that build it stock. Its a terrific flyer.
I used a TT46 Pro on mine. All the power it needs.
