Great answer, very professional, thanks!

"The plane symbol on the map reflects compass heading. In North Up, the plane symbol will rotate with the compass heading. In Track Up, the compass rose and plane will rotate with the compass heading." This statement is true when ADAHRS is normal, what if the ADAHRS is off 60 degree, which...

I'm having a lot of problems to get both ADAHRS to agree with each other!!! When I had ADAHRS-200 out for repair and ran only single ADAHRS-201 in the system, I was able to calibrate the heading within +/- 1 degree. But when I have dual ADAHRS in the system, I could never get both ADAHRS to...

You are not alone, I have had two EGT failed like that, both were the bad connectors. The end of the wire bent like a U-shape, the insolator on half of "U" was stripped, the other half was not, so, when factory installer crimps the spade terminal to the wire, only half of the U was contacted...

RV-7 panel, first flight Sept. 2011

I calibrated my ADAHARS this weekend, after the first attemp, East direction was off for 10 degree (read 100), West was off for 15 degree (read 285), both North and South were right on. Then I recalibrated again, I did East first, then West, then North, then South. All four directions came out...

I have Ray Allen trim installed in my RV-7 and successfully calibrated with SkyView, it worked flawlessly.

Dear Dynon, Thank you for the reply. I have very good sense of how to check the magnetic heading. Like I said, I used both airport compass rose and garmin 496 for reference, and I did roll considerably straight line to stablize the GPS ground track. Both compass rose and GPS ground track...

My SV-ADAHRS-200 is on it's way to Dynon for repair (the magnetic heading was off > 60 degrees). Today I recalibrated the SV-ADAHRS-201 in my RV-7, using the Airport compass rose and the Garmin-496 magnetic heading as reference. I start the calibration from North--> East--> South--> West...

To Dynon, Mine doesn't have the backup battery connected to 7" display because the wire was broken on the backup. Since I've only seen this problem happened once, I'll check the battery volt if it happens again. I hope it's aircraft problem not the Dynon, will keep you guys posted. Jay

Weasel: Is yours a 7" or 10" screen? Jay

I got the RMA # from Mike to return the unit for warrenty repair, but before I got a chance to remove it from the airplane, ADAHRS-200 came back to normal by itself. So far, it has failed twice, what kind of diagnoses you guys do on the test bench? are you able to duplicate the problem on the...

I have two questions for Dynon: 1. How does the Adahrs detects a failure and knows to switch to back up Adahrs? (my Adahrs 200 heading was off for 60 degree, the Skyview doesn't know it's a failure and switch to 201. I have been running the system for 52 hours, this was the 2nd time it happened...

I have exactly same problem with 7" screen, hope we can get the right answer from Dynon.
