Yes, just for future reference remember that stock RTR gearing is normally going to be way to high for a faster, lower turn motor.
You might find yourself going to 2.4ghz like a lot of us have...it makes a lot of things easier and I've never had to worry about glitching since I made the leap.
If the Radio equipment is shot, consider a Spektrum DX2. Its budget friendly, comes with a nice receiver and servos, and Spektrum makes great stuff. Here is a link: http://www.horizonhobby.com/Products...rodID=SPM20200
It is on backorder though. Should be in soon.
In the case that you do need a new radio, it will be beneficial in the long run to get a DX2 or similar 2.4ghz radio now rather than later when you really need it.
