A good friend of mine gave my sons (10 and 12) some old trainers. One has an OS 25 the other a Fox 40. They are working this summer and saving their money. I told them if they would raise 1/2 the money I would put in the rest to get them flying. I've rebuilt the engines. They run great on the ground. Need electronics.

They need a Simulator to play with before going to the field. (I have a 50 acre flat pasture).

But where do we start. They go from free to expensive and I have heard of cables purchased that do not work.

What is the best plan?
