Curtis,
I also have the same flap system in my RV-10.  I have not had this issue but can only imagine that the limit switch that falls into the grooves on your flap position rod is barely being kept in place until the next groove. In flight its possible the air loads flex things in the system just enough that the switch won't engage. A simple tweak of the metal arm on the switch should do the trick. Try moving the switch and listening for the click when it's in a groove. If you have to move the metal arm almost all the way before it clicks then bend it a little so it clicks sooner. I think this will solve your issue.

I tried adjusting the rod a few times and it seems to help for a while.  But it's a pain taking the tunnel cover off and on so I got in the habit of just holding the switch for a half-second or so.  I hold it down while saying "flaps 1", "flaps 2", etc.  It has to do with motoring the rod past the groove long enough to activate the switch.

For a while we had a problem with the flaps getting stuck down.  But that always seemed to resolve itself before we had to do anything about it.  The microswitch must have jiggled back to where it belonged, and that was years ago.  These days we don't see that happening any more.

This might be a good time to plug Vertical Power. With the VP-200 you set 4 total positions and have a sensor for location. You can click the switch down 3 times and it will go down all the way. Click twice to go down 2 "notches". Click up once to go all the way up. Very nice to work with.

I have not affiliation with VP. I just really like flying with their equipment.

Yes two of us here had that problem of flaps working in air but not on ground.Little pressures on the flaps on ground and they would start moving again.After I figured out what was happening I sent mine back and they fixed it and sent two more washers to keep the actuator from rotating so far and wearing away at the guide holes. Had nothing to do with too much grease.
That seems to have fixed the problem. for both of ours. And yes its one Hit down to get neutral the second is half flap and third is full flaps. Alll this was happening around 150 -200 hrs.

Wayne, I haven't done anything yet but I did talk to someone at
Showplanes and they described a fix involving two washers similar to
what Patrick mentioned previously.

My problem has been the gradual degradation of the flap detent
function. It has required 2 or more clicks to get to half or full in
flight and on the ground. Sometime over the next 2 or 3 months I will
open up the tunnel, see if I can understand what is going on and try to
apply the 2 washer fix if it makes sense.

I'll share my experience here afterwards.
