Is it the standard Ray Allen trim motor that Van's has used for years? If so, I believe the two wires that make the motor move are both white. The position sensor wires have colored stripes. I think they're green, blue and orange, but I'm going by memory. The trim motor should have a wiring diagram with it somewhere.
I just did this a couple of days ago. There was a lot more trim tab down deflection (i.e. pitch up), than there was tab up deflection (pitch down). I haven't measured the angles, yet, but I suspect that is by design.Thanks, it worked but the trim deflects the tab more in one direction than the other. Is there some sort of adjustment later on?
Would be easiest to test with the avionics and stick installed.I'm about to wrap up my elevator and just installed the trim motor and harness. Attaching those small wires to the pins was a b***h. I'd like to test the motor now. Can anybody walk me through how to do this? (I'm new to electronics -just ordered the SportAir workshop.)
Perfect. Thanks.The differential in up versus down travel is by design. You need a lot of nose up trim with flap deployment. In cruise, little travel up or down is needed.
