If a radio transmitter isset up for all types of aircraft, and advertised as a Heli system, or Airplane system, the that usually means it it packaged with servos & airbore gear more suited that type aircraft.
Rodney has a good point about getting a system that your club memebers are at least familiar with, so they can help you. If you have never used a computer radio, it can be very overwhelming to learn without a little help. Many guys have computer radios, that have features they don't know even exsist in them
