I have not done the mix yet so I have no idea. I know that at full deflection which was probably about 70 degrees of flap, the plane shot into a straight vertical climb and stalled. I was just doing this for testing at about 4 mistakes high, it was way too much flap for normal use but I just wanted to see what it did.

I have a JR 378 radio with the flap switch that is like a digital trim (beep beep beep) and if I deployed them one beep at a time while also slowing the plane down, it flew good enough that I probably won't mix in down elevator. I only used about 45 degrees of flap at the most for actual slow passes and landings. Did not try them on takeoff but maybe next time.

If you are going to slap them down quickly just be prepared to keep it from doing an impromptu stall turn.
