Yeah, you forgot the elevator.. a key control surface. You don't want big (read.. heavy) servos. You want everything as light as humanly possible. Electric motors don't fly bricks very well..

Normally, the surface stuff and the airborne stuff don't mix. In fact, here in the US, the surface stuff uses 75 MHz and the air stuff uses 72 MHz. If your transmitter and receiver are 2.4GHz.. well, that's somewhat different. What kind of transmitter is it? Is it one of those car transmitters with the knob to steer? If so, well, that's not what you want to fly with.

If your budget is strained, then perhaps an inexpensive RTF (ready to fly) aircraft that comes with the right transmitter, receiver, and servos is what you need.
