Walter, you mention a lot of flex in the Rebel flap mechanism? Any idea
how
different this is from the SR/Moose? We have no flex or slop in the
flaps.

The ailerons are a different story, on a stock SR/M (at least three
that I
have tested) you can hold the aileron and have someone move the stick
nearly
full throw without the aileron moving at all and it doesn't take a whole
lot
of force to hold it. A lot of it comes from the aileron floor pulleys
just
out from the torque tube flexing and twisting slightly on the brackets.
I
have also noticed that the upper side fuselage pulleys will pull in the
side
of the fuselage slightly even with the 5 inch angle installed. I am
going
to add a channel douubler on the outside to stiffen up that area. After
that I am not sure what is "flexing" in the aileron system as it is all
pushrods and torque tubes from there on out. The end play in the
bearings
would add up to a little but nothing like I have seen so far. FWIW.

Peter, I used to run a Warp on my 0320 Rebel, and on wheels, had
it pitched to spin 2350 on take-off. Can't remember the exact
degrees, but definitely less that 13, and somewhere around 11 if
I remember correctly.

There is a lot of flex in the Rebel flap cable mechanism, so you
will always get much less in the air.

Thanks for the replies guys.

There was ice frozen on the bottom of the skis before
I left the
airport. I tried to remove this ice with a scraper.
The lake I was landing on had some spots of overflow,
but not much.

The wheels are about 1" below the skis.

I have a warp drive prop set at 13

Can't speak about the Elite, SR or Moose, as they are totally diffe
rent than the Rebel in that regard. The main problem with the stock Reb
el set-up is the cable. It's something that you just get used to, a
nd the Rebel really doesn't need a lot of flap. There are some things
that can be done to tighten it a little, and I believe some have chang
ed that mechanism altogether on the Rebel. It's most important for fl
oat take-off, but I have mine adjusted to maximize for that and it seem
s to do the job. Also, you want at least 6 degrees reflex which gives
the Rebel an extra 5 mph cruise.
