Default Setup

That is pretty much what I am doing. They were pretty certain about using the 22 over the 11 in my case. Wonder what is different...

Here's one pre-trim. I ended up smoothing out the edges and making the front even.



Here it is just sitting in place. It's a snug fit.
I think that its going to bounce up and down a bit without a front support. I would add an additional aluminum angle up there. If you don't want to drill more holes in the longerons, just bed the angle supports down on some tank sealant and let it cure. I just did that on my -9A.. You will probably want to swap out the standard AN hardware mounting the seat belt cable attachments with non magnetic SS hardware.

You may want to double check the manual or consult with Garmin. It advises against installation near any servo so if you are planning on having an A/P servo, this location may not be a suitable one.

I believe it suggests 10 feet from any type of servos. Unless you're going to mount these on a stick hanging off the plane you're going to be hard pressed to get this type of clearance.

Left wingtip seem to be a long enough stick, isn't it?

Ran into a CAN bus length issue with putting it in the wing. I'll be able to see if I have any calibration issues before I adhesive this mount down.

Check the material strength before you swap any critical hardware. The seatbelt and harness attach points standard AN bolts for a reason. Stainless hardware tends to be weaker than normal AN cad plated hardware.

Please let us know what you find. I am also exceeding it by two feet, partly due to poor planning but I am told that two feet is not all that much since the pervious max length was around 100' and it had worked. This is at least what I have been told.

Yeah,,,,,that would be great if practical but not doable in my -9. I have it mounted on the F-709 bulkhead which puts it "about" the same isolation distance from the pitch servo that I had on the RV-10, about 4 feet. I had it mounted on the bulkhead aft of the aft baggage bulkhead and had no problems with it there so I expect the same here.

Do you know of a reference chart to find this info? I plan on using the SS AN bolts from AS&S but can not find a reference for tensile strength on the web.
