I have the Van's flap system (reflex, zero degrees, half flaps, full flaps). A momentary press down on the panel flap switch will take them down to the next position -- up until a month ago so that now, in flight, reflex to zero to half is still the same but to go from half to full flaps I have to press and hold the switch down until full flaps is achieved. However, on the ground taxiing or at standstill, I don't have to hold the switch to go from half to full, it'll go with the momentary press like it always did heretofore. Suggestions anyone?

I'm having roughly the same problem. Just doing it manually now.

My Show Planes from Vans has always required two taps down to go from half to full. I will pull that whole mess out and install a manual switch if I have any additional faults. One less wire and much simpler to troublehoot or repair. As for landing and takeoff with or without flaps, it is no problem with a CS prop and 260 hp. Having a manual switch would not be any more distracting than dealing with this. It may just be a matter of the micro switch rods not having the cutouts in the right place at the right time. Anybody troubleshot this problem yet?

This is the first email I've read of this thread. Do you really have to hold the switch down the whole way, or does it just have to be more than the normal press? I have seen it where you had to hold it down for a little longer than normal for it to get past the limit switch on the rod. I know that when using a position sensor, the flap position on the ground and the position in flight does not match. I assume that is because on the ground gravity is pulling the flaps as far down as it can, and in the air the relative wind is pushing the flaps up as far as it can, so that may have something to do with it.

Yup. Have to hold the switch down the whole way or the flaps stop movement on release.

The problem is that your actuator pivots a slight bit when you are putting the flaps down and because the 1/8' sensor rod with notches is worn now
the twist that happens when the air flow is hitting the flaps when flying makes it react differently then just sitting. You will need to get into your
tunnel area and re-adjust the sensor unit which mounts to the flap motor. This is a problem with the Show planes unit after a while. Operate your
flaps and watch how the unit twist and you will see it. You need to stop the the flap rod end from rotating so much.
