Flap Motor

[dmaib]

My flaps quit working today, and I suspect the motor at this point. I have looked at quite a few posts on this forum concerning grease getting into the motor and causing it to quit working. Can anybody tell me if the RV-10 flap motors have had this issue? Are the flap motors the same in all of the models?
Any tips as far as cleaning the grease out of the motor would be appreciated, as well.
I plan to hook up 12 volts directly to the motor tomorrow and see whether it runs or not, as a first troubleshooting step.

Instead of hooking up 12 volts to the flap motor how bout tying into the other end of the wires and see if you have 12V when you actuate the flap switch.

I've had to do this twice on my RV8.

I have the Vertical Power system in the airplane so can see that I am getting 12v, but nothing is happening at the motor.

Sounds like grease to me, it's an easy fix.

The VP is not actually looking at the connections to the motor, it only looking at the VP itself.

But, when I activate the flap switch, the VP display indicates current is being sent through the flap circuit. Wouldn't that indicated that power is getting to the motor? If not, I imagine I would get a fault indication from VP. Yes? No?
At any rate, testing the motor directly with a 12v source seems like a good first step. If it does not work that way, then the motor comes out for a look and probable cleaning.

I was thinking voltage in the previous post, I would imagine that if the motor is not running due to grease then the current flow that you see would be very low, much less than normal motor current.

Well, I was getting ready to test the flap motor with a borrowed 12v power supply, but decided to try operating them one more time before pulling connectors apart. Naturally, the flaps worked fine. I ran them up and down about 15 times with no problem. I hate it when that happens. I also took a look at the PDF from Van's that Scremm posted in an earlier post. It seems as if the motors with the grease problem are the earlier motors supplied by Motion Systems. I have the newer motor supplied by Pittman. Has anybody had the grease problem with the Pittman motor?

Twice on my -9 but haven't had to do it in almost 200 hours.
