My engine is mounted on a RANS S-12. It sits on top of the wing in pusher config. There is no room inside the cockpit for a module box.
My solution was to find a suitable container I could insulate and then fabricate a “holder” for it that I bolted to my oil cooler/oil tank bracket.
This satisfies IgniTech’s desire to keep the CDIs off the engine (vibration & heat reduction) while still keeping the box close enough for the wire bundle to reach. It was extremely hard to accomplish due to my chosen box position and having to work over a fabric wing and not being able to lay on the canopy but I’m glad I did it.
I’ll see if I can shoot a couple of pix tomorrow and post them.
___________________ 5 weeks later...
OK. I apologize for the 5 week delay but here are a couple of shots to show how I mounted the IgniTech CDIs. The semi-translucent box is made of fairly thick plastic. I found it at Northern Tool. Be assured that the mount I made from steel strap is very secure. I attached it to the oil cooler stand with AN bolts. I put that square tube under the trailing edge of the box to give it a little slant while keeping it in contact with the aircraft surface. I also drilled holes in the rear wall of the plastic box so as to provide some moving air inside it while keeping water out. The two IgniTech CDIs are encased in white foam rubber to isolate them from vibration.
I have flown 30.8 hours since the installation and am completely pleased. The 912UL started immediately the first turn of the key and the engine seems to run better overall. One of my A&P Buddies who had heard it many times before the installation remarked that it definitely sounded stronger when I flew over and taxied up to his hangar after the install.
I would have liked to have a more "aircraft look" to the CDI box but in this case I am happy to have good performance at the slight sacrifice of good looks...
