Actually lots of folks don't realize how much *rigging* affects performance.
The idea is to be in trim with all three trim tabs neutral (no control
deflection) at your desired cruise. Any deflection of a trim tab results in a
deflection of the corresponding control surface which results in more drag.

Brian,
It would be great to have 3-axis trim on the CJ, NOT because of high control pressures
but rather because of LIGHT control pressures which
we adjust for out-of-trim conditions without thinking about it because
it's not a real problem. The result in cruise cost fuel and speed.
In formation I LIKE to hold back pressure on the stick to dampen any
over responses and turbulence.
Wasn't 3-axis trim something you were doing with the Project?
Homebuilders use MAC servos to good effect, coupled to a "coolie hat"
switch on the stick.

I remember bringing up this subject when I first bought the plane last year.
I have trim tabs on both ailerons, both bent upwards. I never figured out
the logic in that. I didnt want to bend them both straight, since I was
nervous about screwing something up, but now I'm more inclined to bend them
both flat, and then start from there.

Humans are fine for dynamic corrections but not good with static correction.
Trim tabs are much better for that.

That is one of the options. I believe Barry went with the all-eletric trim
option. I opted to stick with stock manual pitch trim and not add aileron trim.
I hadn't decided on whether or not to add rudder trim.
OTOH, if somone wanting the airplane wants three-axis eletric trim I will
certainly put it in.

With a pushrod type control system like the CJ6A has, it doesn't make any sense.
If you had control cables you might do that if they are not adjusted quite right.

That is precisely what you should do. Fly it to see whether there is any
deflection of either aileron from trail (look to see of the trailing edge of the
aileron matches up with the wingtip). Adjust the tabs to get both ailerons in
trail and then go from there.

How do you go about adding aileron and rudder trim on a CJ, sounds like a
major undertaking.

There are three approaches common in experimental/amateur-built circles:
1. bias springs
2. push/pull cable trim tabs
3. small eletric servos
Vans Aircraft offer a simple lever and bias-spring trim system for the aileron
of the RV-series aircraft. The lever just moves spring to supply a continuous
force in the desired direction on the aileron actuator push-rod. This type of
trim should work very well on a CJ6A since the actuator mechanism and the
control pressures are comparable. See
http://www.vansaircraft.com/public/parts.txt to get an idea of how much it costs.
Piper uses this same type of system to provide rudder trim in a number of their
aircraft. It is also quite effective.
Vans also uses a vernier control to move the elevator trim tab in their
aircraft. This would probably work for rudder trim as well but probably would
provide too much static drag for the aileron.
The most popular approach is the small electric servo trim system from Mac. I
don't have a pointer to them but here is a link to an identical system from
another manufacturer
(http://www.menzimeraircraft.com/products/trimsystems.html). These use very
small trim motors and actuators that mount inside the control surfaces. These
may be adapted to the CJ6A without too much trouble especially if you are
planning to recover the control surfaces.

You go to your nearest CJ6 aileron and rudder trim store and buy these two
little people (about 4.5" tall) and place them in the wing and tail cone
with an ample supply of food. You'll also need micro-headsets for
communication to them. Then when you need to add aileron or rudder trim you
press the intercom PTT mic button and tell the appropriate micro-person to
add or take away defection of the applicable surface. If you decide you
want to use the optional "poor man's" autopilot, you communicate with both
simultaneously requesting them to hold position. :-)

Subject: | New books for homebuilders |
--> Yak-List message posted by: sonja.englert@juno.com
Hi everyone,
I would like to introduce myself to this group. I am an aeronautical engineer,
pilot, airplane homebuilder and writer. I have written 3 new books for airplane
homebuilders, which you can check out on my web page www.caroengineering.com.
They are mainly for airplane homebuilders, but should be of interest to anyone
who wants to install engines, work with composites or flight test an airplane.
Cheers,

Prior to 9/11, I wondered what it would cost to get some CJ mechanics
from China here on work visas to set up a couple of CJ's over here.
Just like the World Wide Warbirds in Deer Valley did with Romanians
and the L-39's.
I would pay a *modest* salary and provide all amenities:
Cots in the hanger, porta-potty nearby, shower curtain around the hose
spigot, weber grill, camp stove, a wok, plenty of rice....fast food. Oh yes, a
TV and VCR for Sunday afternoons when they could have off to rest.
Line up them CJ's for annual condition inspection. America, land of
the Entrepreneur.

Camarillo is where I bought my CJ back in '99. Your description matches
my experience exactly. And since it's at sea-level near the coast
airplane performance is awesome (if you're from the hot high desert like
me).

Has anyone any suggestions where to place ballast in CJ6a, C of G man tells me
I need 25Kg (55lb) in tail, I think thats to much that far back so I will put
10Kg (22lb) in tail cone 15Kg (33lb) on loop antenna mount.
Are there any drawings on fitting toe operated hydraulic brakes on cj?

I put 19 lbs in the tail skid and 34 lbs of bird shot in a bag in the tail
cone. Simple, easy, and been there almost 750 hours.

This is not as easy as it looks. If you want to replace the entire gear leg
maybe but than you have the problem of wear difference of the main gear pin.
If the strut is going soft due to a slight leak, you maybe able to correct or
cure this by adding a sealant to the hydraulic fluid in the strut. I can't
remember its name but its in the Aircraft Spruce & Specialty catalog. I had
the same problem, very common on such system, and this cured it right up.

Work the W&B. If the calculation says you need 25Kg in the tail you can't put
10Kg in the tail and 15Kg on the antenna and achieve the same CG. Perhaps 10 Kg
in the tail and maybe 25Kg at the ADF antenna might work tho'. (No, I didn't
work it out so please don't tell me I am wrong. Go work the W&B yourself to see
what produces the same CG.)
Toe brakes on a CJ6A? What's wrong with the pneumatic brakes?

Well, there are several, theres the L-39C which is your run of the mill
L-39, then the L-39ZA and L-39 ZAO whhich have strenghtening in the wings
for armament hardpoints, I beleive there are other modifications for combat
use, then theres the L-159 which is a serious L-39 on steroids.

I just reread your email. You cant just arbitrarily pick where you put the
weight. 55 lbs in the tail will create one moment 22 in the tail and 33
somewhere else will create a completely different moment. Some planes out
there have no weight in the tail, but have a scuba tank behind the ADF door.
Again, the proper amount of weight and where you put it depends solely on
you weighing the airplane and deriving a proper W&B.
If you look at the archives you will find a nauseating amount of info on W&B
about 6 months ago, when I brought up the same topic. In the end I got it
sorted out. Brian LLoyd published all the stations based on a datum 24"
ahead of the props axial plane. Here is enough info to get you going.
CG Range 17% - 24.1% of MAC
MAC = 68.78"
LEMAC = 116.23"
Nose Wheel 57"
Main gear 146.5"
Tail Skid 338"

If you have removed the radios and installed an M-14 then around 50 lbs is
in the ball park, if you have the Housai engine 25-30 lbs is in the
ballpark, but you wont know untill you weight the airplane. I have 30 lbs in
my tailcone with the stock housai engine, and I'm 3% forward of forward CG
with no GIB, and empty fuel.

The aircraft has been weighed and c of g calcuated but my lame was a bit concerned
about putting all the weight in the tail as he was unsure about spinning we
know we have to re-calculate but I didn't want to much weight on loop attenna
mount, we had already mounted battery back on the adf tray and moved both dc
to ac inverters on a tray above main air tank this makes front cockpit much quieter
and I have a very nice baggage compartment.
Nothing wrong with pnuematic brakes I was asked about hydraulic brakes after I
was seen doing my first taxi attempt.

Actually Lou, I have done a set on my project CJ, as has Les Crowder of
McKinney Texas. If your really serious contact me off line. My feeling is
that it works well but after a couple hundred hours in the stock Yak 18
(same brakes as a CJ), I do not think it's necessary. The pneumatic brakes
are every bit as effective.......just a bit different.
Always Yakin,
Doug
