In my dim and distant past I used to fly a turbo beaver, which had a pt6
turbine replacing the round engine, and a fuselage plug and new squarer fin
rudder than the straight beaver. I'm sure there was a wing fence added to
the wing, and I've just looked at some pictures and it's been placed about a
foot or so inboard of the struts - so nowhere near the tips.
Otters have their fences outboard of the struts, where the ailerons and
flaps meet.
I've ordered the new MAM tips for my Elite, so I'll report back when they
arrive. I too have a set of straight Elite tips here surplus to requirement
now if anyone needs them.

I just measured my "first run" Fife tips at about 15.5" so installed
they could add about 14.7" perhaps to the wing. Also found my notes
where Dave advised that MAM recommended shortening them to match the MAM
tips if on floats. I think that comment came from Daryl??
I'm curious as to why Greg's drooped tips slowed his cruise but think
I've heard comments like that previously about the drooped design.
Thanks Greg - real life beats theory every time!
Yeah I understand why a fence between the flaps and ailerons helps with
conventional flaps (or for flaps that go down more than the ailerons)
but I don't know if that is the best place for a fence with flaperons
that droop equally along the whole wing.

fencesHey a little Nitrous for the engine and a little for the pilot to reduce
the pucker factor as those trees draw closer :) Right now I just Make my
wife walk to the next lake and I pick her up there. It's got a lot more
room for taking off and it helps her understand how much we NEED a new
motor. My existing tips don't fit very well and are cracking at the
trailing edge so I had to do something anyways. I've considered wing
theas well but on all the stol kits I look at it seems the fence is placed at
the junction of the ailerons and flaps. I might even do some experimenting
with vortex generators.
I talked to Dean at murphy today and it seems the main reasons for the
new moose tips is the plane was stalling at 58knots on floats plus
insurance companies and transport Canada don't like the high wing loading.
So the wing area increase makes everyone happy. He also said that a small
incease (up to 10") on the rebel wouldn't be a problem. That would make
tip about 22" and I think that's a bit much. I'm planning on something in
the 16-18" range.
