What ESC are you running?

Does this happen at the beginning of running it or near the end.
Nice avatar crash!

it's been over heated or is/has been running hot and is shutting down your esc from excessive amp draw.. It's a Hytech, what do you expect?? :haha: Oh ya, the XRS doesnt like to handle high amp loads, you should be running an rx batt with that low end esc.

Yeah like Dude said the XRS hates big truck stuff. It was more or less intended to run in micro's unless you put a RX pack in.

yeah, that makes sense, since my sphere esc never has had a problem, my lrp cheap piece of **** 39 dollar special one hasn't had a problem with the same servo and running the imex at's, but it has reverse delay, what a piece of ****......ok so then let me ask yall, if i hard wire the + and - into the tamiya connector coming from the servo, will that eliminate my problem? or will it just eventually kill the life of the servo?

You will fry the servo, it is only rated for 5 to 6 volts. There are not to many servos that can handle 7.2 volts. I know of one and you do get 400oz of torque out of it though, and it costs a few bucks.
