Pulled out the TruTrak Pitch Servo yesterday for install in my Ten.  I found 

the

"Installation & Users Manual" with no install instructions for the Servo.

Am I missing something?  Went to the TruTrak website, "Documents &

Drawings" and found two photos.  That's it.  No instructions, no drawings,

and no measurements of any kind.  Anyone else have this problem.  If so,

what did you do?  Install seems easy enough, but I'd feel better with 

instructions

and they're closed over the Thanksgiving Holidays until Monday.  Maybe 

someone

has a copy they can email me?

Chuck,



    We have all had to muddle through this without clear instructions. The 

best way I found was to go to Tim Olson's site and get a feeling about how 

it installs. It is no more complicated than you think it is. You don't use 

the bracket supplied by Van's.

If I remember correctly, TruTrak will give you a more-or-less  

measurement on drilling the hole.  Gauging by the drawings you can get  

a good idea of how to install it and where to drill.  The instructions  

certainly are lacking, though.

Chuck,



I wish I had something I could send you, but after having gone

through 3 total revisions of pitch trim mechanism, I really

don't have much to provide.  The only real concern is where

you drill the hole in the bellcrank.  All the rest is pretty

easy to set up and check out as you go along.  The current

system I'm using is the one that has a wheel and a channel

with a cable.  It's the one that has performed the best

so far.  That one doesn't leave much that needs to be worried

about, as the arm is already delivered to length, so you just

adjust the rod ends.  If you can get someone to mail you the

hole location, you should be good to go by using some

photos.  Sorry 'bout that.  If they ever produce some

documentation in .pdf form that is consistent, I'd love

to have it for my own archives.

I had a bit of a go round a couple of weeks ago with TT on installation of the pitch servo. To help out I printed an instruction manual. The top tech guy said that he would edit my instructions and get back to me, but he is obviously busy and never got back. The biggest problem that I had is with the spacer that is tooooo long. My next post will be my UNEDITED instructions

The Trio servos are the same way. They had a few general suggestions and some photos of RV-6s, but you're on your own. They also gave a pretty good idea on where it fits to the bellcrank.



While we are on the subject, I plan on creating a mounting plate that takes advantage of the two outboard bolts that attach the bellcrank bracket to the spar. The problem is the outboard end of the mounting plate needs support as well. I'm reluctant to drill the spar for a pull rivet - any comments?

Pitch Servo Installation – RV10

As supplied with torque enhancement rail

1. Confirm that a .20” hole has been drilled in the proper position on the bellcrank per the plans for the RV10. Placement and sizing of this hole is of the utmost importance.

2. If it came with your kit, remove (discard or use for another function) the pitch servo bracket supplied by Vans Aircraft. Use only the pitch servo bracket supplied with the autopilot servo by TruTrak.

3. Place the servo unit on a stable surface and remove the stainless steel screw and nylon washer holding the drive wheel and torque rail to the drive shaft. Carefully set the screw and nylon washer aside. Note the small brass screw on the drive wheel so that you can reposition it in the same position as it is when removed. Carefully pry or lift the drive wheel and torque rail off of the drive shaft.

4. Take the drive wheel rail and torque rail. On the forward edge take the eyebolt and screw the Rod end bearing #MM-3-300 into the torque rail approximately half way, using the supplied standard nut as a locking device. Tighten the nut against the aluminum torque rail.

5. Attach the servo bracket to the airframe per the photo supplied by TruTrak. Please note that bracket is attached to the inside right line of bolts adjacent to the bellcrank. Secure the (3) AN3 bolts and the (1) single AN515-8R8 screw and torque to the proper value. Mark the torqued bolts with security paint or colored nail polish.

6. Position the servo motor on the outside of the bracket in such a way as the drive wheel protrudes thru the bracket and the four bolt holes on the bracket line up with the four bolt holes on the servo motor. When you look at the servo unit, the electric motor will be aft and the Connector plug part of the servo will be forward with the connector plug facing outward (away from the bellcrank)

7. Attach the servo motor to the bracket using the four supplied AN3 bolts and the rough washers. Secure the AN3 bolts and torque to the proper value. Mark the torqued bolts with security paint or colored nail polish. Safety wire the four bolts at your option.

8. Reposition the drive wheel in the same position as it is when removed. Reattach the stainless steel screw and nylon washer to the drive shaft (now with the attached eyebolt). 

9. Secure the rod end to the bellcrank as follows: Insert supplied AN3 bolt through the bellcrank from the pilot side – insert aluminum spacer – insert rod end bearing – insert large cadmium plated washer and secure these pieces with 10-32 lock nut. Torque to the proper value and mark the torqued bolts as before.

10. Check that , when moved, the toque rail clears the two retaining bolts on the upper side of the servo motor. 

11. This is a good time to be sure that you have made provision to install/secure the static lines and install any needed security fittings for the wire/s that operate the pitch servo unit.

step 8: Use loctite on the stainless steel screw.

Search the RV10 archives for "TT Pitch Servo Install Directions". I posted the hole location in a follow up email after talking to a TT engineer. The hole location isn't too critical, but don't forget to safety wire the bolts together (thanks Bob). I didn't even see the holes until they were pointed out to me...

Jay

Thanks all who responded.  The bellcrank hole position of 2.25" up and .5" 

aft was all I needed I guess.  I did however, already remove the pulley 

without paying any attention to the location of the brass screw.  Now, any 

ideas on how I'm to get the pulley back into the right/correct position on 

the shaft?

Chuck
