I installed the Kershaw Designs Dual 700 kit on my E-Maxx 3905. Ever since then I've been having glitching problems. I've read here that a better radio/receiver will do the trick to take care of my problem. My question is, what would you guys recommend? I've found the Spektrum DX2.0 for 129.99 and the DX 3.0 for 169.99. I've also been reading a lot on Futaba. Please help me decide!!! The budget must be under $170.00
