Sig offers the LT-40 as a kit (if you want to build) or an ARF. I just bought the Sig LT-40 ARF because I am getting back into RC after a 3 year break.

The first plane that I learned on was a Hobbico SuperStar and that to was a great plane.

I have heard people say that a .60 high-wing trainer is better to learn on because its easier to see. But I have never flown one of those.

Good luck,
Chris
