Has anyone got any ideas about reducing any shock loading on steering servos?

I've got to control 2 electric outboards, linked together with a ball and socket set from a radio controlled car. The link from the servo is normal piano wire with a double kink to try and cut down on any shock loading to the gears but is there a better system?

I'm not sure what you mean by a double kink so I might be advising the solution you already have.

An omega loop in the wire, which as the name suggests is the same shape as the Greek letter omega. Really an open circle(ish). This flexes a little as the wire is moved by the servo or the motors. The drawback is that it might makethe steering 'soft' depending on the gauge of the wire.

You may find this sort of thing will work, most model shops sell them or simfor cars .    Peter

I'd just fit the servo, I don't think the shock loads will be anything like that experienced by a steering servo on a car.

I think I agree with Andy.  Most servos are hardier than you might think.  If that 'double-kink' thingy doesn't take care of the 'shock' to the motors when steered, just make them slightly larger.  If that doesn't handle it... add one of the 'servo-saver' thingys.  And if THAT doesn't handle it, get off the @#$ throttle!, and/or stay out of water that 'solid'.

Thanks for the input everyone!

I think I'll follow the 'progressive' system ala Doc and see what happens, afterall if I end up going in ever decreasing circles then I'll just be following my normal steering technique.
