I have a friend that is stuggling to figure out a radio situation. Here is the deal,he just put a new radio in his truck, he bought a flysky 3gtb, his truck has the traxxas vxl esc/motor and traxxas servo. the issue is when driving the truck the servo response is so delayed and the throttle response is delayed, makes the truck impossible to drive, if your driving it and go to turn it waits a second or 2, before it will turn, throttle response is the same. We tried new battery in the car, radio batterys, receiver, binding and nothing. So i changed the servo and put in a jr servo. It work flawless for 2 6min heat races then reverted back to the same delayed problem. Ive been in rc for 20 yrs and im lost. he put the traxxas radio back in and seems to be working, we'll find out tomorrow at the track. The flysky radio works perfect in his sc, and has this whole time the only issue is the staduim truck. the sc has novak brushless system and airtronics servo tho. Any one have any idea??? At this point im ready to try anything... he just wants 1 radio for both cars.... thanks
