Generally, kits don't come with radio gear. They're marketed for people who already have the equipment, or want to get something "better" than what's typically available in the RTR's.

If this is your first car, don't rule out a RTR. They ALL go as fast as you will be able to handle without experience. If you go with the NTC3 RTR, you can still download the instructions from the TA website if the RTR doesn't come with them. You will find that the instructions will come in handy when you want to upgrade, or when you break something; you will break something regardless of make/model.

I've been really happy with the NTC3, but there are certainly other cars out there that show comparable performance. Get something you like, that has parts availabilty in your area, and have fun!
