    I'm a bit behind in my correspondence ........ haven't been keeping up
with reading the stuff not to mention replying.        I'm curious about the
photo of Perry's aircraft......   I've seen photos of it before, but was
unaware of the unique wing arrangement.   It appears in the photo that the
leading edge of the wing has a jog in it........ Is this a custom
modification common only to Perry's aircraft, or some sort of standard mod
for EZs?

Someone else asked me about this.  The strakes and wings are exactly
per plans.  I put landing lights in the leading edges of both strakes.  There
is a plexiglass cover over the lights that maintains the same profile as the
strake, but in that photo the cover is practically invisible, giving it the
appearance there is a jog there.

    The duct looks so good that I'd be satisfied if it only did 100 mph
cruise..... looks awesome just standing still.

Thanks Howard.  I do all my calculations and data in knots just to be
consistent.  My ASI is in knots. Doing everything in knots makes my
plane seem slower than it really is.  It's can do 145 mph, but normally
does about 130 mph. My next experiment will be with pitch on the
prop.  I have good climb rate, maybe I can trade a little of that for speed.

That may slow the RPM and lose HP. What are the prop tip speeds now?
You need those inflatable lips and a high speed duct.
Try a truck or tractor inner tube.
