RE: Ready to buy a Trainer
If (should) visit your local club before making your radio decision. For your first flights it helps a whole lot to have someone to 'buddy lead' with (connect two transmitters together). For this to happen they need to be compatable (futaba to futaba etc.).
As earlier reply, push the boat out as far as possible on the cost so it can grow with you or possibly make an offer for NOVAflier's old transmitter!
