Servo will only move in one direction
Just starting in the hobby and come across a problem which I'm sure is nothing too difficult to solve. The radio is a Spektrum DX3R pro and the steering servo is a Savox 1251. Problem the servo will only move in one direction when I rotate the steering wheel. If I reverse the servo it still only moves in one direction (Other way) Hope somebody can help
Thanks

Sounds obvious but can you move the servo horn by hand?
If not, the horn could have been mounted at one end of the 'throw' of the servo so wouldn't move any further in that direction... If that's fine its probably a transmitter set up issue.

Tried both method but still no go
Thanks for the replies
I have checked the end points and they are ok (I think). I can move the servo horn both ways so it is not that. If I reverse the servo on the transmitter the servo will work only in the other direction. So the servo will move to both end points but only one direction at a time. I think it is within the transmitter - but I'm only a beginner!!

The Savox servo/Spektrum radio combination is notorious for being unpredictable but in most cases installing a power cap in the receiver solves this, if you're sure all your transmitter settings are correct and you've double-checked everything else it may be all you need:
