hi there got a quick question im running a novak gtb esc with 7.5 motor xxl receicer with crystal and an m8 transmitter with the novak switch. i was haven werid glitch problems when full throttle. Shortly after it started my controller batts started to beep . was wondering if anyone else has had this problem when they go low? havent got to swing by store for more batts or track to re test yet

Low transmitter batteries will definitely cause a glitch. Also, if the battery pack in your car is low, the amp draw from the motor could reduce the voltage to the reciever and cause glitching. Especially if you are running a 4 cell pack with your 7.5 motor. Car battery size was not mentioned in your post.

well i ran a GTB last weekend with my m8 on very low batteries in the main without any glitches but i have had problems with the xxl reciever before so i just run the airtronics reciever and i have no problems
