Van's has a mount for the AHRS that goes right beside the battery. Gary Specketer -----Original Message----- From: owner-rv10-list-server@matronics.com [mailto:owner-rv10-list-server@matronics.com] On Behalf Of Strasnuts Sent: Saturday, March 20, 2010 8:41 PM Subject: RV10-List: AHRS and Magnetometer location on the 10 I don't get it. I read the G3x installation manual and noticed the bracket they use to mount the magnetometer goes on the aft deck in front of the horizontal. Later it suggest to keep it at least 10 feet from any motor or servo. The elevator trim servo is right under the aft deck so I don't get it. Would it be better in the wing opposite the one with the aileron servo? It is a GMU 44. I plan on mounting the AHRS over the battery up high but again the manual suggests to mount it no more than 6.5 feet from the cg. -------- Cust. #40936 RV-10 SB Fuselage N801VR reserved Read this topic online here: http://forums.matronics.com/viewtopic.php?p=291101#291101 ________________________________ Message 2 _____________________________________ Time: 07:13:41 AM PST US Subject: RV10-List: Re: AHRS and Magnetometer location on the 10 From: "Strasnuts" I may do the same with the AHRS.

As someone just about to start on the doors, I am quite interested. Those who follow are greatly blessed by you trailblazers. Just to be devil's advocate for a brief moment, I have a question however. It appears from the video that the cam is held to the axle by set screws. I'm not an engineer by any means, but it seems to my neophyte understanding that the "strength" of the assembly is limited by the gripping power of the set screws. It would be interesting to see calcs on the potential outward pressure on the door from the known low pressure "pull" outside the door in cruise versus the net holding power of those set screws. I assume the set screws are to allow for final adjustment. I am wondering if once the position is set, drilling through the cam/axle assembly and installing a high strength bolt or even a retaining clip might greatly increase both the strength and longevity of the strength of the assembly. One thing I have found in everything from Boeings to Cessnas is that set screws often loosen up over time and vibration. In the spirit of fail safe design, what ever system I end up using (I am leaning toward this one) I would want to be able to sustain closure on its own (without the side pins). As ugly as the VAn's solutions is, I do believe that it has the requisite strength. Of course, my only experience with the whole thing is pictures so I could easily be out to lunch which is why I would love comments by those with actual experience.

"The cabin block is made out of Delrin so it is pretty easy to sand on a disc sander. Much easier than UHMW. When you get the kit you will see the cam is fully adjustable on the shaft. It has an 8-32 set screw to temporarily position the cam in out out and any clocking position. After you are satisfied with the operation you can mark the shaft and cut it and polish it. You then drill through a pilot hole that is on one side of the cam and push a roll pin in that is supplied with the kit. That's how you can change the position of the block on the cabin lip for different builds."

When I got ready to install the backup Dynon, I thought of installing it on the aft deck in front of the horizontal. When I placed a compass to check if this was OK, the compass was 180 degrees off. I guess this was due to all the bolts and screws used in that area. Also that locations could get wet from rain or washing the aircraft. I eventually installed the Dynon's in the other wing tip. The Gadahrs is mounted on the centerline of the aircraft.
