Hi Ross,

Any advantage to top mounting coils as compared to mag cover mounting?

Better access from the sides to things at the back of the engine.

What kind of hardware is needed to mount the coils on top Ross? I?m thinking that there is only enough room for one of the to go up top. In that case I?m thinking likely the right one??

We can mount one coil on top of the case like Les Kearney did and one in a mag hole or on the firewall. Can mount both in the mag holes, both on top of the mount like this setup, both on the firewall. Quite a few combinations for RV-10s.

To mount on top does one just need longer AN4 bolts?

The dual top coil mount is a one piece CNC'd plate designed by Ashley Miller in Australia. It fastens to the engine mount tubes via several Adel clamps and AN3 bolts. You can see several more photos of it about 3/4 of the way down this page: http://www.sdsefi.com/lycoming.htm

Default RV-10 Top Coil Mounts

Hi Randy,

It is hard to see in the photo but the coil mount that is secured to the top cross-bar with 4 x adel clamps and AN 3 bolts is also secured to the angled cross-brace at the rear to stop any for/aft movement.

A 30mm stand off through the rear mounting bolt attached to another adel clamp is needed to keep the coil mount bracket level. I am not sure if this comes with the bracket from Ross.



With the coils on top,access to the rear of the engine,oil filter,heater valves and front strut is greatly improved for servicing.


I hope that helps,

Thanks for sharing Ashley. That is a nice setup.

Mounting on top of the engine, any issues with heat after shutdown? Obviously while running they are being air cooled by fresh air. After shutdown, hot air flows up hill and the coil will get very hot. 300+ degrees F.

The Coil Packs are UF-305 are available everywhere including Australia and Amason Prime for about $40.00usd

The temp range that I could find is up to 180 deg C or 356 F, maybe Ross knows more.
Keep in mind that these coils live buried under the bonnet of many cars that routinely live in very hot climates .

Still it is up to me to test 😀
I?ll report back when I know.
