Servo torque
« on: June 07, 2006, 10:17:49 pm »
I've just bought a couple of 9g micro servos from Fast Components - the company lives up to its name. I need them as steering servos to fit into a very small space, but only now has it occurred to me that they may not have enough poke to do the job.

The quoted torque is 1.2kg/cm. Is this enough to work the rudder on a fairly slow 30" boat?

Jonty, it`s depending some facts: Size of the rudder, is it placed in the propwash a.s.o.
1,2 kg might be o.K.- but I think it is the limit. Anyway, I think you can go on with that, but make sure that in case of damage you could change the servo.

Thanks, Jorg. The rudder is balanced, so I'll hope for the best.

How do you do an umlaut?
