It's definitely worth the money if you are going to be racing. There are A LOT more advantages to a new radio besides just the 2.4 Ghz. For one thing, you don't have to worry about what channel you're own at the track or what crystals you need, stuff like that. You will also be able to make A LOT of adustments for racing such as endpoints, dual rate, ABS, stuff like that. The radio will most likely have a built in fail safe as well. In my opinion, for the money, the Futaba 3PM FASST radio system is the best in its class. I have a Futaba 3 PM and a 3 PK, and the 3PM has more than enough features for me right now.
