Heres a shot of a TC3 of mine with my modified .12 sirio on it. The sirio had about 4-5 mph top speed over the 18TZ via radar gun on the same gearing.

Yep, that engine can only legally run in the open .12 class.

as per roar rules:

For .12 ROAR/IFMAR class engines the maximum number of ports including the exhaust
port is FOUR.
