Posted: Thu Jan 22, 2009 8:11 pm Post subject: Wing Auto Pilot Servos

I'm going to be ready to close up my wings in another month or so, and I 

recognize that I should have everything I ever want in there before I put 

the bottom skins on.  I've not really given any thought to an autopilot, but 

in order to be smart for an option down the road, would it be prudent to 

mount a servo in the wing to set me up for a possible future autopilot 

install?  If so, what kind of servo is recommended?



Another option is to go ahead and close the wing, and hope there's an 

autopilot system that doesn't require mounting servos in the wing.



Thoughts.

maybe go to the Tru Trak web site and look at what they have. The servo is mounted easily after closing up the wing C but it is the five or seven strand wire that controls the servo that you should get in the wing before you close it up C even though I was able to do mine after the fact.

Just leave enough conduit to run the five wire...Its easy to do especially if you ran the wire. Honestly just order the Trutrak servo ind install it now..you need to replace a bellcrank bracket...its. 800 dollar investment you will do anyhow

The ones that I know off and like (Trio, Dynon, and TruTrak) all mount at

the wing bellcrank with a modified bellcrank mount and, while I mounted mine

as I was constructing the wing, I understand it's not a serious problem to

mount them after the wing is finished. Put the wires in there though.

I can't imagine that 99% of the builders won't put in an autopilot,

so I'd just agree with Rick and say "go for it".



One other thing that makes that statement something to consider....



Today I filled in my info for insurance renewal quote.  I'm going to

be getting the AIG discount this year for TAA's.  I think that's

10% off.  But, to get it, you have to have a few items in your plane,

and things like RNP Nav equip, WX Equipment, TAWS and Terrain Equip,

and "2 axis autopilot" are all things that they look at for getting

the discount.  So in the long run, it may actually pay for itself

over many years to have an Autopilot...and they wouldn't put it on

the form if they didn't feel there was safety value there.

And mount the servo bracket before the leading edge is attached to the spar.

It will make your life easier.



While I had the servo in hand, I didn't think of reading the installation

directions since I had the bottom skins left to install.   While it's not

impossible to get the two mounting bolts and nuts in place with the leading

edge riveted to the spar, those with short arms will have difficulties.

Am I missing something?  All of the bolts that hold the aileron  

bellcrank brackets to the spar are held by nutplates which are  

installed along with the tiedown bracket on page 13-5.  This way you  

can pull the lower bellcrank bracket supplied by Van's with the one  

that holds the A/P servo after the wing is closed up.  I'm sure I am  

missing something obvious about what bolts and nuts you are referring  

to.

Andy,

Picking an autopilot is sort of like politics, or primer wars. Everybody has a strong opinion. There are three good brands for us out there, that I know of - Dynon, Trio, and Tru Trak. They all use a bracket mount at the aileron bell crank so you know you are going to have to put something there. Pick a brand and do it now. Here are three web pages to start on:

http://www.trioavionics.com/ProPilot.htm

http://www.trutrakflightsystems.com/instruments.htm

http://www.dynonavionics.com/docs/Autopilot_intro.html



PS: be prepared for a little sticker shock....

You can buy the servo and wait on the remainder.

I would suggest that you make sure you can work on it after it is all closed in.......

I made sure that mne would go in and out the access panels before I riveted the skin on....

Just to throw another one into the mix if you are going with AFS EFIS's they

are OEM'ing a TruTrak VSVG variant soon.  AFS will sell you the servos today

if you call.  Their price is better than TruTrak retail but a bit more than

buying from Van's.



I don't know any specifics on the autopilot but a forum thread on AFS's site

talks about custom programming to communicate with the AFS EFIS displays.
