Fuse beefup for floats?

AGT · Post by **AGT** » Fri Feb 17, 2012 8:48 pm

I'm starting to put the fuselage together on my Super Rebel and wondered if
there are any lessons learned about float operations that would lead me to
want to beef up any problem areas that may have been discovered. I know
that most of the history of problem areas come from Rebels rather than SRs.
Any SRs in operation on floats out there that are telling themselves, "Gee,
I sure wish I had added a doubler here, and a channel there when I was
putting the fuselage together."

I recently had a scare when pulling the leading edge down for final riveting
on my left wing. I had the wing sitting on two by fours and the pushing and
shoving trying to get the leading edge in place caused the two by fours to
roll over sending the wing down with a bang. The entire weight of the
inboard wing area came down on my recently installed heated pitot tube. It
survived unscathed! Guess I don't have to worry about someone damaging it
by walking into it. I mounted it just inboard of the strut attach to
prevent that. Apparently wasn't necessary.

<!doctype html public "-//w3c//dtd html 4.0 transitional//en"> Hi Mike,
We are building SR003 and decided to duplicate the "landing gear fix" (received from MAM for Station 3 carrythrough) at the float attach on the sills at the back. Considering that the tabs on the carrythroughs at the float attach are thinner than at Station 2 & 3 by the landing gear, we thought it prudent to put the fix on the sill at the float attach location.

Mike,
I added two 3/4"x3/4"x.060 angles on the inside of the firewall behind the fus300 channel that runs between the two top motor mounts. The angles turn the channel into an I-beam. The structure is strong enough on paper without the angles but one extra hard landing could do damage.

Hi Al,

Hope you ment the FUS386 channel that runs between the two top motor
mounts, not FUS300.

Thanks to everyone for the beefup recommendations! I'm no Bob Hoover,
especially in taildraggers, so a hard landing here and there is inevitable.
I've already had one ground loop (in a C-150 taildragger) so hopefully
that's out of my system. If the Super Rebel is no more difficult to handle
on the ground than the Renegade Spirit I owned for a while, I shouldn't have
too much trouble after the initial teething period. I can only dream about
the SR being as easy to handle as the Stinson Voyager I also owned for a
while.

Don't worry, Mike ! It's a lot easier than the Renegade, and
at least as easy as a Stinson - and you won't have the crosswind
taxiing problems of the Stinson !! (Our brakes REALLY work ! )
(and the tail's smaller ...) :-)

Then me again...

I have mixed feelings about hearing that the Super Rebel doesn't have the
crosswind taxi problems that the Stinson does. When I am on floats, I'm
probably going to wish I had that big tail. But I do remember taxiing one
day in my Stinson when the wind was howling. I had to do three 360 degree
turns to get to the runway. I would taxi forward, tapping the downwind
brake to keep from turning into the wind until I couldn't keep the plane
going forward (from continuously hitting the brake) then I would allow the
plane to turn into the wind to gain momentum and continued the turn until I
was pointed the way I wanted to go again. Probably a better way to taxi in
those conditions, but that's all I could come up with.

and Bob again ...

I know what you mean !! I've had to do the same thing in our
old Aeronca Sedan - which also had a big tail and not-so-good brakes !
One day when it was icy, I even had Anna out hanging on the wing strut
to try to keep it straight on the taxiway (there was a 6 foot drop off
each side, so a slip would have been messy !). ;-)

I think the Super has lots of tail for float flying - the
Stinsons, for some reason, just never had enough. Even though it
was huge, I guess the fuselage blanked it somehow, as some even
added extra fins to the tail for floats !

On wheels, the Super is much less skittish than the Renegade,
and has a very solid, "big airplane" feel, but it's much lighter
and more pleasant on the controls than ANY recent Cessna !!

You'll LOVE the Super on wheels, and, of course, if it's
anything like the Rebel on AMPHIBS, it'll be <ridiculously easy> to
fly & steer on the ground, and a sheer delight !
