RE: Engine for Midwest Super Stinker
John,
My Super Stinker is still waiting for covering. However, I fly a Cermark Pitts S2B that is very similar in size, weight, and wing area with a Moki 1.35. The 1.35 has plenty of power for all standard aerobatics. I think the 1.50 Irvine should work well in the Stinker.
