I broke my Saito 100 in on my stik for the Stuka. I used the Saito aluminum motor mount which required only re-drilling 2 holes in the firewall and brought the motor closer to the firewall and the specs for the distance of the thrust washer from the firewall. I mounted it with the valve covers protruding at about 7-8 o'clock. The exhaust exits neatly out of the back of the cowl without any cutting to the lower cowl. I have a Hobbico silicone exhaust deflector installed to keep the exhaust from accumulating inside the cowl.

I will probably maiden the Stuka this weekend if the weather permits.
