I have a Brillelli 36GT and it's a great motor.
I also have a CRRC Pro GF26I.
It turns a Xoar 18 X 6 @ 7650 rpm and idles @1850 rpm. Never quits. Runs great, strong, and smooth.
Only complaint is the 1st start of the day is on the hard side, after that a 15-30 minute break, 2 flips with choke ( pop ) and two flips no choke and it's running.
I have just been using a starter for the 1st of the day starts and everything else by hand.
