I don't know what the plane will sell for, I'm guessing 180-200.

Spend 100 on an engine if you can. The LA 40 is a solid motor, for 15 bucks more you can get the 46. The AX series have more power and you will be soooo much happier with. I know in car motors, you spend 300 bucks on a motor that is a pain to tune and its more trouble then its worth. Airplane motors are way different. They run great from day one. OS, you can not beat at any price. You are going to want the extra power. I find it hard to believe that what ever your running in your buggies or trucks or whatever, you have the stock motor in every one. You zoomed something up.

The nano servos are not really good for anything on that bird, maybe the throttle. You have any stock Traxxas servos, or something you pulled for a RTR buggy? Those will work fine. Spend 20 bucks on each servo.
