Status: offline 		Hey guys, havent been around a while but im working on a new build and im having issues. I have a turnigy 125 amp marine esc with no bec, a ubec, and a 2845 watercooled 3600kv motor. the servo is a traxxas 2055 and a traxxass 2 ch 27mhz tx and rx.

http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=10312 - SBEC

Now what happens is when i try to give it throttle it will either turn real slow even at full throttle or i can get it to start revving up but then the servo starts moving on its own. now its not even in the water yet.


so im wondering if any of you guys have an suggestions. even when i get it to start allowing me to rev the motor and turn ill put it in the water but it will only go 5 ft and then shut off and go into the limp mode. if you need a video i can get it up.

Status: offline 		well the servo is fine until i give it throttle and when it finally starts to build rpms then the servo has a mind of its own. i have a new rx coming today and i need to check the esc parameters to make sure its not a nicad.
