I think it's cool to open a new post with all videos about Rvosd !!
Well, Imu test on a super dimona :

Video from yesterday evening. Nothing special, I was just testing AHI for the first time on my TwinStar II. It looks to work nicely, even though I have 3 Z-Sensors instead of XY + Z. Just after start it was not yet calibrated and off, but later after I set neutral positions it was working ok I think.
Elpimous, you are getting 1.36 HDOP all the time. On this situations you should just set "Max HDOP" to 1.40 or something like that, and the OSD will set home faster. However seeing you flying at around 10 mts I understand you want to set home with the maximum accuracy, I still think you should go higher before start making turns around. I only go bellow 50 mts when the plane is going to land.

Yes the AHI is working perfect on both videos, I dont think you have to do anything else with it, enjoy!

Vcc mic signal is soldered directly to current sensor input, like Vova said, but i think/hope problem is about volume !!! I'll try it soon.
And thanks for your tips, ..........Your Imu is amaizing, really !!! some of your competitors work hard to find a solution, and they fail !! (D****N osd).
Jumpjet, on that video I saw one of the best GPS signal I ve ever seem in a video. HDOP solid on 0.80 and 11 sats. I think you need a more carefull tweak of "set neutral rudder" and "set neutral pitch". Nice to see still with the AHI not perfectly set the autopilot worked nice, I guess you have the max roll angle big enough to overcome the few degrees off in the AHI.

To be fair the Dragon IMU failed because Daniel tried to work with a much more complex solution, I also failed with this. Then I realized that the thermopiles are good enough to make an acceptable AHI and stabilization system.

I had several good flights that day and was very pleased with the osd. Like you said, I could have tweaked the AHI a little better but it still performed well even in the wind.
Vova told me he was repairing the board so I hope you will have the OSD back soon.
