So to sum all this up.

1 Wings are not good trainers (trust us we know)

2 Heli motors could be used for an airplane but your esc will need to be programmed for airplane and not heli, also you will be limited on the weight and speed of your aircraft. Suggest a study on motor basics.

3 The mixer avail from tower works fine. plug your servos into the wye and then into your aileron channel. Again, wings are not trainers.
4 Building is fun and experimenting is knowledge. Inventors never fail, they just know hundreds of things that don't work.

5 Lot's of cheap radios and receivers available on ebay and swaps now that 2.4 is all the rage.

6 Check out the s.p.a.d forum for lots of cheap airplane ideas, right after the elections is a good time to p.u free material.

7 Most important, have fun with it. It's a hobby for pete's sake.</p>
