Flap Motor and Actuator Issues
I'm a first time builder who is finishing a RV7 QB kit that was originally purchased from Van's back in 2001. During the flap motor/actuator install today, I checked out the flap motor and could not get it to extend/retract with 12v power. It spins, but doesn't extend. Searching the forum I saw where too much grease could cause this so I took it apart and cleaned it. No improvement. I noticed that when I turn the actuator rod by hand putting some pressure on the actuator it does extend/retract. So I mounted the actuator to my bench in the vertical position, zip tied a couple of pounds of weight to the end of the actuator, and sure enough with that weight it does extend and retract. Is this normal? Seems like it should extend/retract even when no-load, otherwise it would only work when there was aerodynamic load on flaps. Do I need a new motor or actuator?
