but if it is the elevator throw there was a discussion awhile back about
the throw on the SR/Moose. Brian at MAM said they used 20 degrees up and 15
degrees down elevator. 20 up seems like not enough. I can't find the post
from Steve on Ron's Moose up throw but it was 30 or more. They are not
running out of elevator and they have not had any problem with the elevator
stalling with the increased throw. This is all on floats.
The original Moose demonstrator didn't have much (any?) real stall break in
the only power off stalls I did. It just went into a steady decent. Some
will say, cool, gentle stall, but I thought more along the lines of not
enough elevator authority to reach critical angle of attack. More throw
would help arrest the high sink I have heard some getting on landings in
their Moose/SR's,(along with all the other possible ideas out there like
VG's on the wing and tail, cuffs, longer tips, etc.)
Finally to the point - to get considerably more throw on the Moose/SR we had
to elongate the tops of the holes in the bulkheads that the elevator pushrod
goes through or the tube hits/rubs on them. We added an oval inspection
hole in the bottom of the airplane aft of the elevator push rod below the
main cargo floor. We were able to remove the fast builds already installed
pushrod to work on the bulkhead holes by pulling it out the back (also added
a forward hole to be able to remove and install the front bolt.) I believe
that the bellcrank wanted to hit the bulkhead as it was pulled forward for
up elevator also so we made the bottom hole in that bulkhead slightly
larger.
I think with more throw guys will discover, like Murray did in his Rebel,
that the flare is less exciting.

Unfortunate! What airframe, Rebel or SR/Moose. My reason for asking is to
understand if all of us building a SR/Moose will see this.

Hello:
During rebuild after my accident I adjusted the elevator to give about 28*
up elevator which when the slack is taken out in flight is probably closer
landingsto 25*. This makes a real difference when in the flair to land. My
so far have been not bad but it is nice to have this extra up elevator.
Never knew what I didn't have until I re-rigged.BOB said he likes at least
26* up if I remember correctly. Just FWIW. And yes I am back in the air as
homeof today.
THE ACCIDENT
Landed at Int. peace Gardens border crossing to pass customs on the way
offrom OSH.(what a great place)My tail wheel stuck turning left. No amount
andright rudder and brake would convince it to turn right. Left the runway
Thestopped after turning 190* and buckling the fus in front of the tail. All
the damage was contained to between the solid bulkhead and bulkhead "E".
asrelease pin which allows the tail to free wheel had become burred as well
wheelthe round piece which it comes out of was also burred on the sides.This
jammed the wheel in a left turn position. I believe I"m not the first one
that this has happened too. Before you go flying again you might want to
take the tail wheel apart and have a good look. I filed my wheel into "G"
and have installed a Scott 3200.This is like day and night with an 8"
back there. It really feels good. I also added a dorsal fin which will
strengthen the tail section up a little also.
Good luck to all
Murray
