I have a brushless setup in my emaxx with the 27mhz tq traxxas am radio and reciever and it is almost undriveable because the glitching . Sometimes I will be going full speed and it will glitch the brakes and start tumbling going 40 or 50mph. Is there a better am or fm i can get or should I just save up for a 2.4 ghz radio and reciever?
