Being that we're way beyond beginners we just spent all day Saturday experimenting with my buddy's Avistar. Flapperons make a HUGE difference in glide angle, and minimum landing speed with NO loss of control. We had landing and take off in less than 30 to 40 feet with about 5mph headwind with 40 - 45 deg down flapperons. I was even temped to run out and catch it on a few low/slow fly-bys (no I didn't).

I agree lower pitch/idle might be a better solution but the question was about flaps.

2 extra experiments...
- 4" x 4" speed brakes that come out 90 degrees on both sides of the fuse will slow it down too... a lot but block the horizontal stab for moderate loss of control.
- Replaced the flapperons (stock ailerons) with double the cord ailerons resulted in even more slow speed fun.
