Once you have a system, the next thing you should do is look at flight packs. Mini servos are wonderful for all kinds of things. Buy a couple receivers and a couple battery packs and a good field charger. Obviously you don't need to buy it all at once, but having extra flight packs means you don't have to move your radio back and forth between planes. Plus if you buy a variety of servos, the possibility that you'll have the "just right" servo for any given application increases.
Yep... never too many servos or RX's... I'm up to 3 RX's for my 6DA (which is not a computer radio...) and 4 for my Super-7 (which is an ancient computer radio... but has been regularly serviced. Its about 15 yrs old now.) Most of my recievers are the standard 7 channel. one 8 channel PCM, one GWS micro. about 30 standard size servos... 2 HS-81, 4 assorted micro servos.
But I've been accumulating these things for years... and yes, I do occasionally do have one plane RTF for each RX.

When buying a "flite pack" compare the price to a 4 ch system. Often the system is cheaper. (just order it on the same channel... and turn the TX into a buddy box for the club. and you still save money.) You can special order a system an get the servos you want.... and still get a system deal discount (making the TX and charger free...)
