I usta race K&B 7.5 class F-1 boat in the S.F. Bary Area in the mid 80's, great engines.
My favorite airplane "ringed" 2-stroke was the K&B Scream'n .48, fantastic glow engine.
The Scream'n .48 pushed (pulled) my World Models P-51 to over 100mph.
My friend Gere put 2 Scream'n .48's on the World P-82 Mustang, WHAT A SOUND!
