RV-8 ADAHRS location

[Larco]

Looking for suggestions on where to mount AFS/Dynon ADAHRS on an RV- 8. It seems that the canopy metal frame maybe problematic when opening and closing if the ADAHRS is mounted behind baggage bulkhead. Anyway any suggestions are appreciated. Thanks,

I have an AFS 4500 in my RV-8. The AHRS (crossbow I believe) is mounted behind the baggage bulkhead on a cross member that bridges the upper longerons. Sorry, no pictures.

One mounted in the tail between the L and R horizontal stabs. The other on the inboard inspection panel under the right wing. Both work well. Dynon.

This is where I put mine. It works well but is difficult to access with one hand now that the turtleneck is on.

I think it would be easier to work on if it were mounted under the longeron and further forward... Maybe next time

Hey Larry, One of the RV-8 guys here at Livermore mounted his GRT ADARS in the left wing tip.

Thanks everyone. appreciate the info. Hi Danny!

AFS recommends mounting the ADAHRS box(es) on a bracket between the upper longerons, just forward of the tailcone bulkhead where the static ports are located next to (that is, the static port location as per Van's plans). If the turtledeck is already on, this can be a tough place to drill accurately because the upper skin curves inward above the longerons and at least for me and my old shoulders and bifocals it was an impossible contortion challenge. I mounted mine in the same location but on the middle longerons and believe it will work out well (as it has for others). But I have not flown yet, so no actual experience to share. If it turns out mine are too low (the steel rudder cables are closer in this configuration, but that's about it), I will extend the bracket to lift the boxes up a bit, simple enough.

I have great success with mounting the Dynon ADAHRS in the LH wing inboard inspection panel on my RV-8. Makes for a short run for the pitot and AOA lines if you use the Dynon pitot tube. The inspection panel sits at zero deg in pitch as related to the wing spar, but you will have to shim the wing's dihedral out, which is easy to do. Very easy to access in that location and relatively free of ferrous metal influence.

Here's mine: http://www.marksrv8.com/category/avi...-panel/page/2/. I have had no problems with the canopy frame.

Here's one option.
