Gene,
I actually like the manual flap lever better.I modified mine to fit better next
to my leg. 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...

Gene,
Wouldn't change a thing except for me--changing my manual lever for the electric
kit---would be an improvement. I HATE that damned manual flap lever. 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.

Hey gang.............Educate me, and discuss this situation I would like to do
to my RV-4...I would like to fly a normal Fighter Pilot traffic pattern, but
my fixed pitch prop still provides some thrust even at idle, so I have to be
almost out of sight on final to ever get it to slow down...To install a speed
brake somewhere is too much for me, (and where?) sooooooo how about this: Modify
my flap system to allow the flaps to go down to 90 degrees so I can get the
proper airspeed on final and still be able to see the airpatch...LET ME HEAR
FROM YOU...Be kind!
CHEERS,
