Hi Jesse,
Well, every tip I've dealt with has been an easy install. If you made the
top of the wing and the top of the tip parallel, in other words allowing for
the thickness of the glass, the flaps/ailerons were a dead straight line. In
fact I found it was easier to set the neutral point of the rigging off the
tips rather than trying to set up the way the manual describes.
I guess I'd make sure that the tip is parallel to the top of the wing in
several spots and that is where I'd set them. That would be the most correct
for air flow so you wouldn't get a "heavy" wing.
I guess I cannot see how the tips are twisted, but anything is possible.
IMHO

[rebel-builders] RE: Installing Fife hoerner tips
Thanks Curt and Rick,
Well, I drilled and clecoed the left tip yesterday With the trailing edge
lined up with the flaperon the tip sticks above the wing about 1/4" at the
main spar, so indeed there is some twist i.e. compound curve in the top
surface. I just hope the right side is the same. I plan to line up the
trailing edge there too. I also plan to use the tips as the main reference
for setting the flaperon neutral position, so I really hope the tips are
symmetrical. In fact that is the main reason I am installing the tips at
this point: I am getting ready to temporarily mate the wings to the
fuselage, and one of the tasks will be to build the fairing boxes at the
flaperon/fuselage intersection. I purposely postponed building the fairing
boxes so I could hopefully end up with both sets of flaperons, tips, and
fairing boxes all lined up straight. The one thing I can't control is where
the tips trailing edge will end up, so that's why I did that first. Again, I
can just hope that they will be the same on both sides, otherwise my plan is
toast, and I'll have to use an ugly trim tab or something.
Does anyone have a good way of measuring the flaperon neutral position? The
best I can think of is to put a straight edge on the bottom of the wing and
measure the distance from the straight edge to the bottom of the flaperon
trailing edge.
Thanks
Jesse

There was no twist in my tips.
Symetric is more important than aileron to tip and wing box alignment
though. Thing is that the flaperons sag on the teleflex. Adjusted for
neutral in flight, mine sag at least an inch on the ground. With a notch
of reflex for inflight, they sit up a bit on the ground.
Nother comment about the angle drill discussion awhile ago. All the
attachments that require two hands to use are not near as easy to use as
a true angle drill which only requires one hand...

[rebel-builders] RE: Installing Fife hoerner tips
Thanks Ken,
Yeah I am probably wasting time worrying about it. When I built a lot of RC
models a non-straight trailing edge always bugged me. Maybe I can have a
notch on my flap handle "ground viewing" and have everything lined up to
make me happy.
