Dr_Jim Posted November 12 Report Posted November 12 Is it normal for the electric flaps on a 69 M20C to go down at a different rate than they come up? I my case they seem to come up half as fast as they go down, the mechanic checked the gear box and there are no issues there. Thoughts?

I my case they seem to come up half as fast as they go down, the mechanic checked the gear box and there are no issues there. I’d start by measuring voltage at the actuator and compare the up-circuit voltage to the down-circuit voltage…

In the newer planes it's two different relays. you might have some corrosion on the relay contacts. My relay had two sides to them So I just switched the wires to the other side. 3
