As Ken said, this is a good step. You can get the 2.4 gig radio system any time and STILL use the servos with the new receiver. So, do what you must, and enjoy the Four Star 60. It's a great plane. One suggestion, though, on your maiden, do that with an instructor with the buddy box attached. Fly a few tanks with the buddy box system to get used to that low wing setup as compared to the high-wing trainer. They are quite different.
As far as the 2.4 Gig systems are concerned, don't get all concerned about brand names. Get what you feel is good for you, no matter what it is.. Futaba, Airtronics, JR, Spektrum, all are worth every penny they sell for. Check them out closely and buy what you like.
I have two Airtronics 72 MHz systems, an RD6000 and an RD8000 system. I also have a Spektrum DX7 2.4 GHz radio system. I love them all, they work just fine and do whatever I demand of them. Airtroncis has the new RDS8000 on the market now, and the price is very competitive. Very worth taking a look at.
Best of luck with the Four Star 60!! I'm sure you will like it. I had the Four Star 40 and loved it. I traded it with another guy in the club and he still has it and flys it. Great plane. (oops, I already said that

)
