[rebel-builders] Rudder Spar Question

[Drew Dalgleish]

Hi Craig The spacing of your ribs needs to match the pre-punched holes in
your rudder skin.

You know, Drew, I thought of that but was still unsure about any extra
length remaining on either the top or bottom. The rudder skin isn't as long
as the spar.

My 1998 electronic manual still gives the same measurements that you
quote. Unless someone remembers better than me I think the manual is
correct in this particular case. Suspect you need new spars or must
shorten the stab/fin/elevator/rudder a bit which would be a lot of
opportunity to make even bigger errors. Many of us found that a second
hand kit was not quite the bargain it appeared to be but it did get us
started and new spars would be a minor thing in the big scheme.

This is a handwritten change??
I'm not MAM but page 7/27/94 was part of my original manual and it does
not mention spar length. I can't find any evidence that MAM ever issued
a bulletin to change anything there. Certainly nothing with that date.
That said I wish I'd made my rudder spar perhaps 1/16" shorter to better
fit a nylon washer in between the hinges. Note that all the Rebel
bulletins did end in RB or REB to specify that they were not for the
biplane.

Hi Ken,

Thanks for the reply. The manual update is from MAM...it's a single page
which outlines steps 6,7, and 8 or something like that. (I'm at work right
now). Also, how can the measurements be correct if they tell you to cut
the spar to 46 1/4" and then have you place one of the rib location holes
at 46 7/8? Seems like it'd be a little tough! How did you handle that? I
checked Wray's rebel site and his re-written manual; he doesn't mention the
"cut to length" step but shows the same 46 7/8" rib measurement.

As far as the kit goes, I'm reasonably certain that it hasn't been messed
with based on not only the appearance of the components and my impression
of the seller.

It's a mystery so far.

Ummm both my manuals say to cut the spars at 47 1/8"
I don't understand why yours are shorter. Guess you need to confirm that
with someone. My plane is not close by to measure.

They are shorter...because someone finally woke up maybe!? Ever since MAM
changed the rudder horn to the thicker one, with the milled out ends for the
cable attach, the rudder won't fit the fin attach bracket spread anymore!
Bob has it right...build your Fin first!

I'm building the rudder now and have hit a little stumbling block. My
kit
is a '92. (207) I'm at the part where you cut the rudder/elevator spars

to

length. In the manual, there's a one page update put in by the previous
owner dated 7/27/94 which says to cut the spars to 46
