In case you need to replace it, I have an unused RV-10 flap motor that came with my kit. I replaced it with the newer style during the build, so I never used it.

Subject: Bad flap motor?
Today the flaps would not fully retract. After a bit of troubleshooting I found they would retract if I gently lifted the trailing edge while commanding "retract" with the switch. Everything seems tight. The problem is repeatable. I have the Showplanes positioner but this is happening between positions so I don't think it's related. Seems like a weak flap motor but don't know why it works from full down up to about 1/3, then needs an assist for the final bit. It's not super scary, so we plan to finish our trip. Have others seen this? The motor is from 2007 with about 2500 hours so wouldn't be too put out if it failed! --Dave

Might be worth checking voltage at the motor (and the ground path). A loose connector, high resistance crimp, etc could make the motor seem weak.
