    Subject: Trim & Rigging
    --> Yak-List message posted by: cpayne@mc.net 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.

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. -- Brian Lloyd 6501 Red Hook Plaza, Suite 201 brian@lloyd.com St. Thomas, VI 00802 +1.340.998.9447 - voice +1.360.838.9669 - fax

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. -- Brian Lloyd 6501 Red Hook Plaza, Suite 201 brian@lloyd.com St. Thomas, VI 00802 +1.340.998.9447 - voice +1.360.838.9669 - fax

    Subject: Adding rudder and aileron trim (Was: Trim & Rigging)

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. -- Brian Lloyd 6501 Red Hook Plaza, Suite 201 brian@lloyd.com St. Thomas, VI 00802 +1.340.998.9447 - voice +1.360.838.9669 - fax

    Subject: Re: Trim & Rigging
    --> Yak-List message posted by: "A. Dennis Savarese" <adsavar@gte.net> 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. :-) Dennis Savarese ----- Original Message ----- From: "Ernie" <ernest.martinez@oracle.com> Subject: Re: Yak-List: Trim & Rigging > --> Yak-List message posted by: "Ernie" <ernest.martinez@oracle.com> > > How do you go about adding aileron and rudder trim on a CJ, sounds like a > major undertaking. > > Ernie > ----- Original Message ----- > From: "Brian Lloyd" <brian@lloyd.com> > To: <yak-list@matronics.com> > Subject: Re: Yak-List: Trim & Rigging > > > > --> Yak-List message posted by: Brian Lloyd <brian@lloyd.com> > > > > cpayne@mc.net wrote: > > > > > 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.

    Subject: New books for homebuilders
    From: sonja.englert@juno.com
    --> 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, Sonja Englert www.caroengineering.com

    Subject: Trim & Trash Talk
    --> Yak-List message posted by: cpayne@mc.net Dennis 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.

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.

Are there any > drawings on fitting toe operated hydraulic brakes on cj? 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.)

    --> Yak-List message posted by: "Ernie" <ernest.martinez@oracle.com> 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" Ernie ----- Original Message ----- From: "Lou Dakos" <lou_dakos@bordermail.com.au> Subject: Yak-List: Ballast > --> Yak-List message posted by: "Lou Dakos" <lou_dakos@bordermail.com.au> > > 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? > > > Lou > >

    --> Yak-List message posted by: "Lou Dakos" <lou_dakos@bordermail.com.au> 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. Lou

Last year I trash talked in order to heat up the blood of all the young Serria Hotel sticks but all I got was a lady who couldn't get insurance for the event. Go figger.

    --> Yak-List message posted by: "Doug" <rvfltd@televar.com> 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.
