RC2013 Posted September 1, 2014 Share Posted September 1, 2014 Hello I have a fg marder 23cc and most recently the steering servo has begun to give up. When turning right it wont respond. I can hear it trying. Left turns but weak. Charged the battery and the throttle servo seems very lively so thinking the battery is good. Any ideas?? Thank you Quote Link to comment Share on other sites More sharing options...

RC2013 Posted September 1, 2014 Author Share Posted September 1, 2014 Whats a servo saver. How do i check the voltage. At the servo itself? Quote Link to comment Share on other sites More sharing options...
Shudson Posted September 1, 2014 Share Posted September 1, 2014 Checking voltage at battery is fine, with everything switched on and, ideally, the servo moving. Quote Link to comment Share on other sites More sharing options...
Mike1970 Posted September 1, 2014 Share Posted September 1, 2014 Disconnect the servo and try it, then try to move the steering by the linkage to make sure it's free. 1 Quote Link to comment Share on other sites More sharing options...
RC2013 Posted September 2, 2014 Author Share Posted September 2, 2014 Out of interest how much voltage should there be? Quote Link to comment Share on other sites More sharing options...
Mike1970 Posted September 2, 2014 Share Posted September 2, 2014 In theory, if it's a 6v battery then it should be around 6v if it's charged. Check the other things first to see what the problem is. Quote Link to comment Share on other sites More sharing options...
atom3624 Posted September 2, 2014 Share Posted September 2, 2014 Definitely follow Mike!! CAREFULLY - don't strip the gears - unscrew the retaining screw in the servo and GENTLY lever off the servo arm. With the servo disconnected, feel how free moving the steering mechanism is. ALSO ... Power up, without the gear connected, and see how the servo moves under power; left, right, left ... This should give you some ideas. It might be the battery. It might be the servo. It might be the linkage ... Al. Quote Link to comment Share on other sites More sharing options...
RC2013 Posted September 28, 2014 Author Share Posted September 28, 2014 So i took the steering gear off and tried the steering and the servo is non responsive. Checked voltage at same time and it stayed at around 6.1v. What you think guys, servo knackered? Can they be serviced? Quote Link to comment Share on other sites More sharing options...
atom3624 Posted September 28, 2014 Share Posted September 28, 2014 Gears may be worn / jammed. Depending on servo, you can get replacement gear kits. Might want to consider a more powerful servo. How was the steering - free moving when not connected to the servo? Al. Quote Link to comment Share on other sites More sharing options...
RC2013 Posted September 28, 2014 Author Share Posted September 28, 2014 Yes pretty free moving although locked up at full lock and needed to be pushed by hand to release. Do you know of any servos for sale? Quote Link to comment Share on other sites More sharing options...
RC2013 Posted September 28, 2014 Author Share Posted September 28, 2014 Should it be free all the way? How would i fix that? Quote Link to comment Share on other sites More sharing options...

RCbutcher Posted October 2, 2014 Share Posted October 2, 2014 The above is making me feel better about the ts700 it looks very similar to the hv one but not the same. but aslong as it's fairly reliable ill be happy. Is the horn size big on them like 8mm ish. Quote Link to comment Share on other sites More sharing options...
