hi back again with more problems, i have recently been upgrading my TQ hummer, i have fitted a jetpro pipe and a new high torque servo to work with my new front cable brakes. when i have put everything back together and started her up, when i hit full throttle the revs cut out and the failsafe kicks in and applys the brakes, its a bit jerky all the way up the revs then as soon as i hit full throttle the revs cutout the failsafe kicks in and the brakes go on. its not the new servo as i have put the old one back in and the same thing happens i know it must be some kind of electrical fault maybe my receiver or something but everthing was fine before i upgraded everything has anyone had the same problem or can anyone help:scared::cursing:
