Fabbed up a mount for a Dynon ADAHRS unit. I cut a piece of .025 sheet to dimensions per Dynon’s web site, then laid out the mounting holes. I cut two pieces of angle to fit between the longerons behind the F809 bulkhead. This moves the ADAHRS unit away from the bearing on the bellcrank. I was able to locate one of the angles so as not to interfere with bucking rivets when aft skin is installed, but the other angle may cause a problem. I may have to use one cherry rivet on each side, but that shouldn't be an issue.
