Does anyone know how I can check to see if my rebel kit #207 has the
upgraded wings? The seller told me he ordered it as a 1650 gross so it's
supposed to be. How do i tell?
Thanks Craig

The most obvious difference that I remamber is an extra nose rib 6" from
the root.

Hi Craig
I'll look up details if you need further but from memory:
Doubled leading edge root rib with a channel like doubler on the top and
bottom of that rib.
Extra leading edge rib 6" outboard from the root.
(root means the most inboard rib)
approx. 1" x 1/4" doublers bolted to the top and bottom of the spar
centered on the strut attach point. The top one is about 3' long, the
bottom just over a foot.
There is also a 32 thou doubler rivetted to the spar under the strut
attach fitting but that might also be on the 1500 lb wing.

Ken,

Is there any way to tell if the spar doublers are installed without
opening the wing? I can see the extra ribs and the strut attach fitting
but cannot see anything that would be a telltale for the spar doubler.

Hi Garry

They are invisible from the outside of a finished wing. You can see them
if you have an inspection hole in the wing skin behind the spar at the
strut connection. That inspection hole was optional when I did my wing
so you might or might not have it. One could also see them or feel them
with a finger if you put about a half inch hole behind the spar. You
could probably make a half inch hole underneath the strut fairing so
that it would not even be visible. Any chance there is a gap there big
enough to see through? Or if you have an inspection hole ahead of the
spar look for AN3 bolts about every 3" along the top and bottom of the
spar in that wing bay. I suppose a long pole and mirror might also let
you see them if you removed the wing tip and got a light down there.

I have no idea of your aircraft's history but if the wing root upgrades
look original rather than retrofitted I think it is highly probable that
the spar doublers are there as well but I guess nothing beats seeing
them to be certain.

You're right. Seeing is believing. You just have to know what you need
to see. After nearly 3 years experience with this machine and not having
built it, I am getting somewhat confident that I could buy/inspect one
without missing much. I will do that inspection in the spring when I
plan an extra heavy duty annual to look at everything I can think of.
Thanks Ken.

Garry...I'll save you taking the wing tip off.

I "up-grossed" those wings from the original 1450/1550lb design, after
aquiring FOKM from Bob P., by opening the root rib...adding the extra
leading edge rib at the 6 inch mark, adding the reinforcing angle W161 and
it's associated hardware to the front attach point and put it all back
together. No there is not the 13" long "spar doubler/backer" at the wing
strut attach point and if you read the manual it was and still is an
optional install for 1650lb gross wings.

Hello All,



I'm working on the torque tube in the wing. I'm at the point where I put a
sleeve, end cap and control horn on the outboard end of the tube. This is
the horn that will attach to the flaperon horns. The instructions say to
bolt a horn to the cap and do all the various drilling of holes in the
sleeve and end cap. When it comes time to assemble, the instructions don't
mention the bolt/nut at the end cap. I'm wondering if it's just an omission
or what. I can't imagine leaving the center hole empty. Also, if there is
a bolt, it would need a nut plate, right? Or is it like the others, and
require a wired bolt as a safety? I'll probably call Jeff on Monday unless
someone has a definitive answer. Wayne, are you out there? Anyone? Thanks
to all. Craig
