McCauley Prop / W.D. spacer / Amphibs
Posted: Fri Feb 17, 2012 8:56 pm
Curt, that McCauley sounds like the same 76 x 54 (Cessna Cardinal) "clip
tip" that I installed on the newly refurbished 150 H.P. Amphib Rebel. I got
it from Howard (142 hours SMOH) and he had previously had it pitched finer
to -50. I test flew her for the first time on Sunday (no wind / empty weight
1167lb / 30 gallons US fuel / me 195lb = 1542lb takeoff weight) and it was
off the ground in <LESS> than 450 feet (off fairly long grass). The distance
took me by surprise, as I had my wife about 300 feet further down the strip
for the inaugural picture. I had planned to hold her on the ground and
rotate it in front of my wife (that's hold the plane down and rotate the
aircraft for you gutter minds!)! The aircraft had other things in mind!!!!
Cruise at 2450 rpm was about 105 MPH by the a/s indicator, which seemed
fairly accurate (had no GPS on board to confirm!). Flew around in circles
for 2 full hours until the temps dropped on the newly overhauled engine, to
indicate ring seating, and then brought her home with very tired arms and
legs. She wanted to turn left heavy and required enough right rudder to make
my leg go numb! Don't know how Bob P. flew her this way (mind you there was
a bungee on the control stick that I had removed!) but after15 minutes on
the ground readjusting the water rudders (as they were offset right, in
comparison to the aircraft's rudder making it get pulled to the left) and
installing a trim tab on the right flaperon I took her back into the air for
another hour of flying. She now goes straight and level completely HANDS OFF
! In cruise she needs absolutely no elevator trim (up or down) and with the
power back coming down final, to fly hands off, she only needs a very little
"up" elevator trim. (Firewall in original position, with large battery in
back about 30 inches behind the rear float attach points).
AND if anyone has any reservations of their abilities to fly on amphib
floats. It's like landing a king size Radio Flyer wagon! Just fly her on and
let her roll! Like a tricycle gear aircraft with another training wheel to
help it along straight! No flare, not bounce, no full stall 3 points
landings or ballooning back up into the sky!! I know the no flare bit, as I
was on the ground both times before I realized I was that low and it still
held the nose wheels slightly off the ground, until slowing down on the roll
out!!!

you guys allowed to use a prop like this? J

I think the Yacht is the way to go, if they supply the bait. :)
Thanks again for the help.
