Van's Yaw Servo Mount

As someone that didn't like the idea of dropping $750 for the Garmin yaw kit I'm quite interested to hear what others have done with the Vans -14 kit. Anyone have photos of their install? Raabs, what are you thinking of doing, going with the Vans kit or using the more expensive Garmin kit.

After looking at the two kits on the workbench, the only differences are the 1/2" shorter Vans bracket and the Garmin price $490.00 more expensive. I think the -14 kit will be fine.

I would also like to see pics of somebodys intall of the -14 kit in the -10.

Btw, what I did for my 10 in order to delay purchasing/installing this (since it may change until I get to avionics) was simply to not install the top rivets on the bottom part of that bulkhead - lets me install it later somewhat easily (maybe with cherrymax rivets?).

anyone reverse-engineered or home-brewed a tiller arm/bow for the Dynon yaw servo? Seems very pricey for what it is, and easy to fab from a bit of aluminum plate and an old hacksaw blade

All we'd need are a few major dimensions for hole spacing; the rest is eyeball-engineering with an eye towards keeping the cables from possibly fouling with anything.

I am stuck in the middle debating whether I should be putting electric rudder trim in my plane or not. This yaw damper will technically work like a rudder trim once engaged correct??

I asked that question of many folks, including Rob Hickman and dynon engineers. Generally from the engineer types you hear that you also need trim. Those flying will say you don't need it. I've heard the latter from enough people whose opinion I respect, that I'm going without rudder trim.

I started this process of mounting this today and here was my findings.

When I mount everything according to the drawing as shown in this picture, I will need to drill 2 new holes per side into the frames and bellcrank ribs. Rivet spacing should still be ok at .25 in o/c. Additionally, I will convert the middle 470 rivet to a 426 flush rivet to remove the conflict.





When I utililize the existing holes ...you guessed it the mount sits 1/2 inch proud of the bellcrank mount. The spacing for the bottom two holes results in 1/2 inch too low. I think this might explain why the mount from Garmin is 1/2 in taller...to mount in the bottom two holes.

Resurrecting an old thread: Does anyone have part number for just the Garmin "bow" - I'm going to use the Vans bracket for yaw damper on my RV-14, and can't find a part number for just the bow/arm as opposed to the very expensive full Garmin mounting kit.

Thanks

Yeah, what do those engineers know, anyway...🤔

Could it be that the servos are much better at changing a position than continuously holding one? <rhetorical>

Good point, but with the damper centering the ball and the AP maintaining the desired heading where would adjustable rudder trim come into play, unless you were hand flying the plane?
