Terry, I think you opened yourself wide open on this one. There are many ways to skin the cat and still leave nine lives open. I have used Logger32 since its inception for Antenna switching and Rotor

Hi Brad, I have used a prop pitch drive motor for about 30 years and it is still going strong. There were several models available surplus and it depends on which one you have. There is also a mod to

Running without oil/grease is a definite NO No! With the high ratio gear box, the Motor and initial gears are running at several 1000 rpm. They definitely need lubricant. * 73's Jim W5IFP * mlcntusmu

I have had pretty good luck using an impact wrench set to low torque. The steady pulsing seems to break them loose without twisting them off. WD40 does not penetrate very well. I would try some autom

Roger, You must be talking about some other type of rotor. A little more about my Prop Pitch drive. Mine is the small size. The gearbox is modified to give a 1900:1 gear ratio. The drive motor is ra
