McCauley Prop / W.D. spacer / Amphibs

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!!!

Blue skies,

Hi Wayne,
Thanks for the reply. I got through to Warp Drive and they highly
recomended the pinning too. Good thought on the bushings, I think thats the
way I'll go even though the ones in it are steel. I'm doing the dampner too.
Just seems safer to me. It's great to
have an Experi "mental"
So, I have a McCauley prop 76" 54 pitch, bulkhead and RED spinner. It
is unfortunatly labled expermintal, but the prop shop that looked at it for
me 150 hrs ago said they would fly behind it. It has one station that is
.001 to narrow, even after the paint.
It just dosen't give me the the static runup I feel necessary for float
ops. The shop said that they could try to change the pitch, but were
reluctant. It gives me 2300 rpm. Probably would work better on 160hp. Are
you guys allowed to use a prop like this? J
ust curious.
I think the Yacht is the way to go, if they supply the bait. :)
Thanks again for the help.

Hi Wayne,
Yeh, that sounds like the same prop. I do know mine came from a 1969 c172,with a 160hp 0320 e2d. The prop shop that o'hauled this one is very reputable, and they are on my field, so when they acted reluctant to try to take it to 50 pitch I didn't push the
Idea.
Thanks for the numbers on the rebuilt amphib. Did you happen to do the weight and balance? I'll let all know what the change to the warp drive does to mine on wheels and then again on the floats. Curt N97MR

McCauley Prop / W.D. spacer / Amphibs

Posted: Fri Feb 17, 2012 8:56 pm
by Wayne G. O'Shea
Guys/gals, there is going to be a builders TEST on all of this at the end of
June!!!!!

IF you had of read the whole thread on "McCauley Prop/ W.D. Spacer /
Amphibs" you will see that the previous message, to the one you are asking
about below, states that the firewall is in the original position (ie: is
not cut back) and the battery is mounted about 30" aft of the float attach
points!

With Howard's Amphib, we mounted the battery back between bulkheads "D" &
"E". This really helps with the C of G and also leaves the entire floor
available to sleep on, after mooring up on a Northern Lake! Note that the
MAM manual does not show a floor here, but I always install the extra 20"+/-
section of corner wraps and floor back here, and put the pulleys on the back
side of "E".

Take care,
Wayne G. O'Shea
