Not sure about the 10 but I installed one in a Glasair III and the owner raves about how great it is, I'd like to figure out how to install one in my 7

The -10 can have a bit of a tail wag in some conditions, but I never felt the need for yaw dampening(and I am a bells and whistles kind of guy).

i think it would be pretty cool, but not $1,500 cool.

That was my opinion too.

I think we'd all agree it's not a "must" have, but the -10's I've ridden in so far do seem to have just a smidge of tail wag, particularly in slow[er] flight and mild or greater turbulence. For example, flying the 90kt VFR arrival at OSH made it definitely noticeable, but I can't say I noticed it as much at normal cruise speeds. It is much more noticeable in the back seat than the front seat as well. Keep in mind too though, I'm speaking from only a small amount of flight experience as opposed to the many others on this forum who are already flying theirs.

I had to laugh at the "$1500 cool" comment. We are going with the YD on our build, and I hate to throw Sarah under the bus here but it was one of the few "better-half better-haves" listed for this build. It was already suggested to us by a local friend who has been flying his -10 for many years now and designed his own YD mount for his sorcerer a/p system... but once we got a ride in one with Sarah in the backseat, it went from "cool" to written in stone.

Anyway... since you're only asking about the 307 panel itself, I thought that they were the same price with or without the YD button? If that's the case, I'd almost definitely recommend getting the one with the button, in case you ever do want to install it later. Downside is of course, you'll have a useless "what's that do?" button if you don't actually install a Y/D servo.

Best of luck!

The cost for the 305/307 is the same with or without the Yaw button, price of the servo is $750.
If you're planning a system get the unit with the yaw button then if you decide to add yaw damp all you need in one more servo.

the servo is 750 but then Garmin wants 750 for the mounting bracket. The mounting bracket seems somewhat overpriced for what it is.
