I have flown my RV4 for 1500 hours and never burned up a flap motor...:) STOL ops are way improved with "instant" flaps. You can deploy them during the takeoff roll for a hop into ground effect on a very soft field, and retract them instantly on landing to get better brake effectiveness. I also like to extend them during slow speed dogfighting. Much better turn circle below 100 knots...:) Your mileage may vary...

A speed brake or 90 degrees of flap seems excessive. I would think that swapping to a constant speed set up would be the preferable solution. Slowing the RV4 down is certainly a trick. I start well before the "standard" a-beam the numbers approach and pull the throttle back to about 1100 rpm (0-360, fixed pitch), dump all the flaps at once at 100 mph and hit a somewhat shorter turn to base then final. I use a touch of throttle to adjust descent rate and I am usually successful in crossing the fence between 65 and 70 without having to fly a long and risky final. It took me a while to get it right. My goal is a constant speed set up sometime in the future. D.
