<DIV><FONT color=#000000>&nbsp;&nbsp;&nbsp; First of all, there were a few small

I made mine, so I made them from steel, but I'd be VERY surprised if Brock
can't tell the difference :-).

I don't think so.  All the aileron inserts are the CS-1's, and all the
elevator inserts are the CS-1A's.  I see no reference in the plans to any
CS-50's, that's a Brock designation from something else - probably the L.E.

Sounds like Brock's selling CS-50's when they should be making and stocking
CS-1's, as called out in the COZY MKIV plans.  They should definitely NOT
sell CS-50's as though they were CS-1's.  They DO list CS-1A's in their
catalog, though.  Gee, a QC problem with Brock - how surprising.

Nat, you should contact them about this and ensure that they stock the
correct parts.

PS - Bill, please turn off HTML/MIME encoding in MS OE - set it to send in

Now I am getting confused, My #536 plans call for CS-50s in the list on page
16-1. Maybe this
was where the error originated. If the  part is called out wrong, then I
ordered the wrong part, did
I miss a correction to the plans?

Actually, I have to say Brock treated my very well and replaced one of the
inserts I had destroyed
in the process of fitting(smashing together with the assistance of heat and
cold). I dealt with Mike
at the Brock plant who did everything he could do.

Subject: COZY: CS Inserts
Date: Wed, 3 Mar 1999 11:07:22 -0600

People,
There is confusion on the CS inserts which I will try to explain. First of
all, our practice has been that if there is a Long EZ part in stock that
works, we don't design a new part, or give the same part a different name.
Okay?
Well, originally there was only one rod insert, and that was CS(for control
system)-l. It was aluminum, supposed to fit inside an .035 wall tube, and
was tapped 10-32. Then some Long EZ builders were bending the AN-3 rod ends
to the elevators, when installing and removing the canard, so the CS-1A was
born, which was drilled and tapped for 1/4 x 28 for 1/4" rod ends, and
specified to be used on only the elevator push rods. Then a Long EZ had an
engine fire and Burt decided the aileron push rods ought to be thin wall
steel, so the CS-50 was born, but it was made of steel with an OD to fit
inside a .028 wall steel tube. The CS-1A was switched to steel at the same
time, although not necessary, and it was not given a new name because the
dimensions stayed the same. The change from CS-1 to CS-50 was reported as a
design change  in the newsletter to all first edition plans builders. The
nomeclature was changed to CS-50 in the second edition plans. To summarize,
CS-1A is used on the elevator pushrods (for strength) and CS-50 is used in
the engine compartment for fire resistance. There will be another change
coming up, and that is the OD of the CS-50 will be reduced, because .028
wall steel tubing is very difficult to obtain, and most builders will have
to use .035 wall tubing. In reviewing this in the second edition plans, I
see that I didn't increase the OD when the designation changed to CS-50,
but I don't have to make a design change, because the OD is being reduced
for all new production. Clear as mud, huh?
Best regards,
Nat

People,
We have a tolerance on the OD of CS inserts of plus or minus .001, coming
from one source, and the tubing they fit in from another source has a
tolerance on wall thickness of plus or minus 10%, and you may get either
.028 wall or .035 wall tubing, so it is almost guaranteed that you will
encounter some poor fits. It is better to have an interference fit, because
then you can either ream out the tubing, or chuck the insert in your drill
press and sand or file down the OD. If the fit is too loose, riveting in
two places should solve that problem. The only other solution is to make
your own inserts to fit. Sorry, all mass produced parts face the same
problem. Everything has to have a tolerance. It is a fact of life. 
Regards,
Nat

Date: Sat, 6 Mar 1999 16:29:34 -0600 

Have had the control system sort of installed as I made the pieces last
winter.  Now the canopy is installed and the latch mechanism in place.  The
latch pieces are made according to plans.  Finnaly doing the last install of
the control system.  The stick grip interferes severely with the latch or
vice-versa.  I can shorten the stick mounting about 3/8 in before the grip
runs into the arm rest.  This leaves over 1/4 inch yet to go.  Could shorten
the canopy latch arm or reshape it by angling it forward 30 to 45 deg.
Would have to make some sort of new catch.  

Any one else using JD's excellent grips run into this?

    You're the first to ever have this problem in a canard (that I know of ) in over 7 years of
selling my Stick Grips.  Can you e-mail me a pic?  I may have some ideas :-) .

I use a piece of alum. tubing about 4" long with touring bicycle tubular foam handlebar grip material. The push to talk switch 
is at the top of the tube mounted through a handlebar end plug that comes with the grip kit. Its lightweight, doesn't get in 
the way, and is cheap. The feel is nice, and in long haul flying like  is most of ours, your hand isn't on it that much 
anyway.

I am using the MAC sticks and ran into the same problem.  I made a new
front latch piece out of 1/8" 2024 and it worked well.  I used the original
Brock piece to trace the top section and then modified the bottom to be
further forward.  Hope that helps.

See CSA Newsletter of July 1994.  There is a simple, cheap, and light
approach to using small needle bearings in the article.  If you need
details, e-mail me directly, or get the issue from Terry Schubert.

I have:
forward of control stick - ball bearings
aft of front seat - plastic (delrin I think) bushings
firewall and wing root - stainless steel spherical bushing bearings (look like a rod end with a cylindrical O.D.)

Use lighter trim springs, Steve Wright's comment while at the controls. its the lightest control force Ez I have flown.
