There are also a number of small foam electrics that might offer you an inexpensive way to learn the actual flight controls. GWS makes an electric Cub and a Tiger Moth. Both in the 30 ish wingspan range, and they sell for around $45 with motor and gearbox. (Unfortunately insufficient power for your Convertable.) But the low EDF (Emotional Debt Factor) of a cheap foam plane is an advantage.

Good info from Jett. Just make sure the Laser 4 (or similar) you order comes with mini or micro servos and mini receiver. For Hitec it would be HS- 55 servos and 555 receiver.

Good luck, and ask away.
