Dick,

Why couldn't you just make your own?  It is a little more work, but
definitely doable.

Here's what I'm gonna do:

1. If you look at the installation instructions for the
servos(http://www.trutrakflightsystems.com/documents/LegacyPitchandRoll.pdf)
, you're asked to assemble everything before bonding in the brackets.  Make
sure all rod ends are installed with everything neutral--you want an equal
amount of adjustment in and out.

2. Cut a piece of 1/4" phenolic large enough to bolt the servo to.  Make a
hole for the actuator.  Make this piece larger than you think it needs to
be--a couple of inches larger than the servo all around should work.

3. With everything assembled (including the phenolic bolted to the servo)
you should have a pretty good idea how to trim the phenolic such that the
servo is properly positioned. Study the installation material available from
TruTrak and positioning becomes fairly clear. You're mainly concerned with
pushrod alignment here. The servo should be positioned to allow full
movement of the pushrod without interference. After you have the up/down
position nailed, trim off the top edge of the phenolic to just above the
servo.  Leave about an inch left and right.   BTW, you might find this
easier using a piece of stiff cardboard.  You can trim/shape the cardboard
until it looks right, then transfer your "pattern" to the phenolic.

4. Flox the bottom edge of the phenolic to the fuselage floor with everthing
assembled.  The servo/pushrod assembly ensures the phenolic is properly
positioned.  You'll probably have to find a way to prop up the servo so that
its weight doesn't tip over the phenolic while the flox cures.
Alternatively, with everthing assembled, make very good positioning marks
(use something to scratch the fiberglass/carbon fiber), then flox in the
phenolic in reference to your marks.

5. Since you have an inch of extra phenolic on the left/right ends, you now
have room to build and flox in support bulkheads (again, look at the
pictures).

6. Finish the whole schmeer with a 3-bid layup over the entire bracket and
at least an inch onto the floor.
