fjaust: That motor, fuel and the servos will be fine for the job. The 539's might even be a little overkill but use them as they'll feel a little better than standard servos on the precision side while flying. Everything you got is great now just make sure you don't put in a brick of a battery (ex. 1800mah nicad) in it just to make sure you keep the weight down and you'll have a great rig.
