Before I would commit to the 9C I would first check to see if a 75 single frequency module is avaliabe for it which I beleive there is. It is a very capable radio with the only down side being in order to change frequencys at a competitive event you would have to buy additional rather expensive modules on another frequency. I believe it has storage for eight models.
My preference would be for two others that are just as capable in your application at slightly less cost but offer the tremendous advantage of synthesized operation. This is the ability to change frequencys at will (legally) in just a few moments without a bunch of expensive modules or returning for a retunning.
The first is the Hitec Eclipse 7 with 75Mhz Spectra module or the older Prism 7X with the 75Mhz module. The Eclipse has storage for have storage for seven models. The almost as capable Prism has only three model storage but the advantage of a discontinued model is quite inexpensive on the used market. In that case you would by the Tx and just pop for a new 75 Spectra module. With the Spectra system to change channels you just pop out the module and dial in the new frequency and put the matching crystal in the Rx. Crystals are relatively cheap.
The next choice would be the new Tracker 11/ Seeker system sold by Polks Hobbies in N. Y. This radio in fully synthesized meaning you just punch up the frequency desired and the Rx will automatically adjust. One huge advantage to this system is it has storage for 99 models.
In the united States Radio systems are sold with either negative or positive shift which means only rx's of the same shift are compatble with your tx. Both the Tracker and Hitec have a feature called 'Shift Select' that makes them compatble with all brands of FM Rx's. I am not sure the 9C has this so if you go that route I definately research that because it is a huge advantage as you mature into the sport and possibly even explore other venues such as aircraft.
