Riding the truck today, it seemed to have lost its bond. I figured it was the on board hump pack dead. Brought it in, put the pack on charge for a few hours. When the truck is turned on, all i am getting is a red light on the receiver. However it is not doing that normal glitch with the servos when the batt's are turned on, it will not link to the remote. I have not tested to see if I was getting power to the receiver but it seems as it does as the light does come on. Also the hump pack charger recognizes it being plugged into the pack. Now a few hours later I can bind the two and servos work as they should, however once I turn the truck off, back on the become unbonded again..Could the receiver be toast ?? I am not sure what is going on here ?? Thanks
