There have been numerous installs aft of the belly panel access hole with no claimed issues.  Fabricate a mounting bracket which you can adjust for level and then you can fine tune transverse level with plastic shim washer if necessary. I used aluminum rivnuts with epoxy and brass screws to avoid any ferrous type fastners.  Good luck!

From the Dynon installation guide

Physical Installation
Observe the following guidelines when choosing a location for an SV-EMS-220/221 Engine Monitor module:
• Do not install on the engine side of the firewall.
• Avoid locations that are subject to severe vibration.
• Avoid locations that are subject to extreme humidity.
• Leave ample working room for electrical connections.

This should give you some ideas

Good to hear! Looks nice think I'll follow suit.

Thanks for response and info.

Contact Mark Pensenstadler by PM.   He built a Cruzer and is building a SuperDuty.   Both are full Dynon equipped.

Didn't see his video on it although I've watched several. Enjoy his work and info.

Thanks for taking the time to respond and link!

My discussion on the MGL SP-6 Magnetometer details how I mounted it aft of the belly hatch.  Although the mount is not adjustable, with the use of a digital angle finder I was able to perfectly align it with my SP-7 AHRS mounted alongside the central tunnel under the passenger seat in my STOL 750.  West G-Flex has always been my go-to epoxy - when applied with a "scuff through wet epoxy" method, the underlying aluminum will deform before the epoxy bond lets go!

I've had zero issues with the magnetometer in this location.  However, the SP-6 uses a computer chip and an algorithm "that is able to cancel out the effects of magnetically active parts and materials on board the aircraft without any form of external aiding. Very high levels of heading accuracy can be achieved even in very compromised mounting locations where the combined effects of field distortion levels exceed the strength of the Earth's own magnetic field." (Quote from MGL)

It was truly amazing to watch the magnetometer dial-in the compass heading all by itself on the calibration flight!  It has remained extremely accurate ever since.

Thanks John. 

Sounds like works well back there so I’m going to close out my wing and skip a remote wing mount unit. 

Appreciate the help!
