I've found a low budget 2.4Ghz radio combo--Tactic TTX-440. I'm running a Mini-t and Cup Racer off of one controller, so now I'm gunning for the conversion in my Xmod. I considered a brushed ESC to run with the 2.4Ghz receiver as I'm pretty happy with the fairly quick motors I'm using from Eric @ Main-iac Motors, but I think it'll make for an interesting build to go brushless using an ESC/Motor combo for the Micro-T.
I think 2.4Ghz is totally worth it. I run my cars on my street where there are some high powered lines and those powerlines can cause some serious "ghost driver" action. Had my mini-t slam head on into a 6" high curb that did not end well. I used to get it on my Xmod as well.
Other bonuses of using 2.4Ghz are no protruding antenna, they are fairly small receivers, no crystal swapping, mega range, quick transmission between Rx and Tx, and probably more.
Too me that's all worth it.
