Quick question for anyone with Rotax 912 experience out there. I'm doing a clean sheet design and need to get the firewall details nailed down.

I'd like to know what people recommend or have in their airplane for the minimum spacing behind the engine mount and the closest part of the firewall.

There is a bunch of stuff to go back there and I'm not sure how much space to leave. Bonus question if anyone can tell me if the spacing should be different between the ULS and iS.

Thanks all!
