Congratulations Buly! I still remember my first flight, it sure is different
from the first solo in the 152.
On the exhaust, I believe there are two things to be considered. First the
general item is vibration, which is an issue on Pistons and Rotary. The
second is the heat in connection with the shock wave, which is Rotary
specific.
Solutions? I believe the exhaust must be decoupled from the engine either
with sleeves or flex joint. I had the same problem on the SOOB until I put a
flex joint in. On the heat and shock wave? I would think what Ed mentioned
is probably something to start with.
FWIW

Keep working, you will get there.

Thanks Richard, I was thinking along the same lines. Lucky for me I have here all the tools to form ball or slip joint. And the main man in the production deptm races rotary cars on weekends :)

Lucky dog!
