For those who have the flap pre-select system: I am at stage to decide whether I want this system or not. My question is whether it can be adjusted to select reflex, trail, 1/2 and full flaps? Or can you only get 10, 20, 30 degrees?

That is exactly what you get – reflex, 0, ˝ and full.

If I did it again I think I would rather have more control over exactly how much down flap I could use past zero. At times full is too much and 1/2 is not enough but I'm just being picky I suppose. I do like the zero setting for take off vs. the reflex or -3 degree setting. I've found the difference being at zero the aircraft just flies off without much back pressure at all with an overall increase in climb performance. In the reflex position you need a bit more pressure to rotate and take off.....that extra one inch of pull is wearing me out! The system works great though.

I see no reason for any more than these 4 settings,
but by cutting a couple more notches you could
add a couple more steps if you really felt it necessary.
The way it flies though, I see no need for any more
than what it has now. I think, but have not
measured, that it's reflex, 0, 15, 25

Ok for the people that don’t have the FPS or have not used it yet. One point of order. You can put your flaps at any setting from -3 degrees to full (?25 degrees). All you have to do is go down to the preset (anyone), then hit the up switch until it is at the desired setting.
Now, after 100 hours I have not needed to do that because my empty weight CG is further aft than the Vans aircraft. But when I was doing my transition training, I was taught to put the flaps down, then bring them up just a little, or else you run out of elevator trim for landing…

Yes, you can stop the flaps anywhere mid travel by centering
the switch. Just yesterday I used it to give more partial
flaps so I could take photos of the wife in the cherokee.
you'd be amazed at how hard it is to fly side-by-side
with a plane that doesn't WANT to stay that slow. Yes,
the RV-10 flies nicely at slow speeds, but it cools better
at higher speeds, so to try to maintain 90kts
for 30 minutes, you have to pull out some tricks. Partial
flaps when needed aren't tough, even with a 4 stop positioner.

During transition training Alex D. demonstrated that it actually takes about 200-300 feet more roll on takeoff if in reflex instead of 0.

If you take off with the flaps in reflex and you have a problem that makes you need to go slow as in engine failure C you will tip stall your wing instead of allowing the inner portion of the wing to stall first. This would not be a good thing. At least with sailplane design and other aircraft C tip stalling the wing is a bad thing.

I like it. I flew in another RV10 that does not have it. It is not really a big deal to just set the flaps manually. Still, I like the simplicity of the system. It is easy to install - uncomplicated to operate and relatively foolproof. I also installed a little Ray Allen sensor (the 1.2" model) that shows the flaps position on my AFS3500 EFIS. My only note is that the change on the indicated position on the EFIS from reflex to 0 degrees is too small to show an indication on the EFIS.
