Question Mounting the NAZA H GPS Module at an angle

Does anyone know if the GPS module can be mounted at slight angles to the heli mechanics, or must it be on a parallel line?

Have you tested like this?

Thanks,

Steve

If it were just the GPS you might get by with a slight angle, but the GPS puck also contains the compass and I don't think that I would like that at an angle.

I had also posted this question on another forum and a well known pilot replied saying that he has two mounted at small angles and they work. I am going to try it myself and see how it responds. I do agree that too steep an angle will mess up the compass.

I will try to remember to post my findings here so future pilots with this question may stumble on this and have an answer.

Thanks for your feedback Tahoe Ed.

Because the NAza has a compass in it an magnetic north is different than true north, I use the NOAA.org web site to find the magnetic deviance and then set the gps puck off to that degree. Here in Seattle we are 17* off true north buy in Oklahoma city they only 5* off so set the gps puck off according to you magnetic deviation in you area.

Hey 300c, thanks for that info. I have read that somewhere else and actually found a US map that shown how the magnetic deviance looked. Might even be the one listed.

What I was looking for was level does the GPS/Mag module need to be relative to the heli. I found out it could be at an angle of 10 degrees and it would still calibrate fine. I did NOT fly the heli to see how well it worked. Mostly because I ended up mounting the GPS module in a different spot than originally planned. So now it is level in reference to the mechanics. But I think it would still work if off a few degrees +/- from level.

I also found another thing anyone who will be flying with a fuselage, as I am, to watch out for the magnets that hold the top and bottom fuse halves together. This one got me for a couple nights.

Steve
