Go to [link=http://www.spadtothebone.com]Spad to the Bone[/link] and look at the plans there. Which plane are you building? If its your first gas plan, follow the Debonair plans. Easy to build, and the plans are quite easy to follow.

Do you already have a transmitter? If so, just by a flight pack (receiver and 4 servos) on the channel that matches your transmitter. If not, buy a complete flight kit that contains the transmitter, reciever, and servos. Pick a channel thats not very crowded at your field. The flight pack will come with the receiver crystal installed in the receiver. Don't try to change the transmitter crystal unless your a licensed technican. Federal regulations prohibit unqualified personnel from changing transmitter crystals, since there may be additional tuning to be accomplished.

The debonair plans are detailed as to recommended locations for receiver battery, servos, and the receiver. The antenna from the receiver will just be routed out through the fuselage and trail behind the plane.

The servos that come with the receiver will have polarized plugs that only fit into the receiver one way. Plug the servos into the reciever and then use the transmitter to determine which channel controls which servo.

Good luck.
