Have you madeany adjustments to the tx? I remember that my axe motor won't spin unless throttle is at full bottom on the tx, couled your tx be out of adjustment? I am curios about this problem and look forward to you fixing it so if we have the same prob we can find the answer. Inaanswer to rotor13 idea that I use my ps3 controller, I have a usb convertor for xbox cont but I can't seem to get all control actions to corespond to the ones on my tx. I will keep trying.
