Hi everybody,
It's time now for me to install my engine in my plane (an OS 160 FT twin cylinder).
But, if I fix my engine directly on the firewall, it's too deep in the engine cowling.
My idea to bring forward (about 10 centimeters) the engine fastening is to fix this one on :
- 4 threaded screws, screwed in the original firewall
- 1 aluminium plate where the engine will be fixed.

My questions are :
What do you think about this technique ?
Which threaded screws diameter do I have to use ?
Which aluminium plate thickness do I have to use ?

Thank you by advance for your help

Thierry
