I know this has been discussed before, but I'm at the stage of building where I'm thinking about pitch trim speed reduction. Can anyone who's used a resistor for a considerable period of time (several hundred hours) tell me if there have been any problems with that approach? I'm assuming that the acuator motor still has sufficient torque with the reduced voltage to do the job, & that it is not harmful to it - is that correct? I'm wondering if a pulse width modulator (PWM) would be a better approach, as the voltage to the motor remains normal & the same for the torque. Here is a link to a possible device costing less than $10 with free shipping (although I think I'd do the registered mail for an additional $2.30) -

This looks like a very small unit. I like the thought of a simple resistor & switch, but the PWM would give complete variable speed control & possibly be better for the motor. I'd appreciate any comments.
