Help Please

I have a K3 and recently installed a new radio JR XS3 Pro. I kept the Novak receiver I had installed but under full throttle my sterering servo goes crazy. So I installed the new receiver and I get the same result. I switched to another JR radio and got the same result. Under almost full or or full throttle my steering servo goes nuts and my throttle servo glitches. Sometime it wont go back to neutral. With the engine off all the radio equipment works fine. I cant figure it out any help would be great.

Since both servos are misbehaving, there's a good possibility that you have a defective receiver.

SOunds like you may have something metal to metal rubbing causing the glitching. Try checking your center diff linkages, Brake linkages . Anything rubbing metal to metal will cause havoc.

thnks i have been working on it for a few hours now and sometimes when I pull full throttle and let go it only moves a little back to center and cant conrtol either the steering or throttle until I manually push the throttle servo back to center then it works fine till I pull full throttle again. I can blurp the throttle as long as I dont go full weird. thnks for the help

well i pulled the motor cleaned it, oiled it, and put it back together. I then inspected the throttle/brake linkage and it was fine. I clean the pipe replace both the exhaust gaskets, one on the engine and the one in the inline pipe. Reinstalled the motor and pipe and I get the same. Under full throttle everthing goes crazy.

disconnect the throttle servo and try plugging a spare servo into the throttle hole in the rx. see if it does the same thing. if it does- do the same with the steering servo. if it stops glitching on either channel then that servo is bad.

not very likely but i have seen it happen one other time.

if the servo is bad, you may also have to install the spare sevo to double check. if it starts goin nuts again, then the problem is most likely in the car (linkage or other metal to metal).

Thanks for the help guys. I have solved the problem. THe battery packs lead was loose and under the engine vibration was becoming intermitent with its contact. I dropped in a new battery pack and bingo problem solved. Big ups to Mike the Snake Rbproducts forum for his good call on the battery.
