YS .60 FR

My Dad differs...our Blue Angel world champion replica had dozens of first flight witnesses. We ran the brand new motor for 4 - 5 minutes on the ground with an APC 12 x 8 and the old school Hatori muffler only needing high speed needle adjustment with 15% Cool Power fuel.. Second run, first flight...8 minutes of cool.

-does not need 30%
-does not need a pipe
-generally runs out of the box
-Is the most powerful classic pattern engine!
