Empty C of G-Rebel on Floats
Posted: Sat Feb 18, 2012 12:01 am
Is your step position now the same as on the MAM 1800's? If your
splice was all ahead of the step, and even with the noses 3"
forward, that would move your step and therefore wheel position
back quite a bit. Then you would have a lot more weight on your
front wheels which might explain why they are harder to hold off
on land. Probably on water it wouldn't matter, and not sure what
effect a more rearward step location has.

FOKM's a >BIT< ahead of that empty C of G Walter.
Pretty close to 10" (on
the 9" side of the line!!) thanks to the float noses
being 3" further
forward to keep the rear attach strut 90* to the
float. The step was 3"
further forward on the 1500's before I diced and
spliced the 21" into the
step area, so this moved the nose bumpers 3" further
forward than a typical
1800 installation. Firewall is not moved back and also
running a metal
propellor. Probably more a pilot (ME) technique
problem... than a real
problem, but the 20 lbs of water worked perfect until
I get better at "water
fun".

problem. I stillWhat was your empty c of g with these floats? Mine is still a
little nose heavy at 10.7, but I never had thaton pavement,have the battery in the front, and now also the heavier metal
prop, but my firewall is back 3 inches. When landingbefore touchingthough, I don't let the nose wheels get too highdownwind anddown the mains, so they never have that far to drop, so don't
ever remember them banging down. Water landings always seem
comfortable, and I've done some pretty aggressivedown too fastglassy water touchdowns. Many years ago, I used to fly an
ultralight on floats that liked to dig in, if I wasn't fast
enough on the stick, but not the Rebel. If I touchbounce up, and Iwith the Rebel, the worst that happens is theyagain. I'vejust need to hold it off a bit longer before landingno adversedone this when flying low due to fog and low clouds, and not
knowing exactly where the water surface was in glassy water
conditions, and it just touched and bounced up witharound 70pull or dig in. Mind you, I kept my speed down in these
conditions, with the flaps lowered, but it was still*------------------------------------------------------mph. Normal touchdown speed is around 50 mph.

Battery is only part way down the tailcone! It's a
bulkhead behind the rear
float point and it needs to be moved right to the
back, the same as Howard's
and that would fix the "teeter totter"!
I was just playing around and found that a gallon of
water in each rear
compartment was perfect for the time being (and much
quicker than actually
working on moving the battery!) and if loaded up just
pump the water out and
the ballast is gone. Also when I stretched the 1500's
into 1800's, due to
differences in the distance from the step to the rear
mounting position, the
nose of my floats are 3 inches further forward than a
factory set of floats,
so this adds to things as well.
Without the ballast, solo and 1/2 fuel it didn't
matter where the flaps
where, I could not hold the nose wheels off when
landing on pavement and
they would immediately bang down. With the gallon of
H2O in each rear
compartment I can hold the nose wheels off the ground
down to 45MPH and then
they just settle lightly with full up elevator input.
