I love my 210's. There easy to start, easy to tune, and extremely reliable. I run mine on Omega FAI with added (3 oz per gallon) castor.
The Pitts M12 was scratch built from my own plans about 7 years ago. It weighs in at about 15 lbs and flies like a dream.
The Stinger is a blast with the 210. Hovers at 1/3 throttle.
Curt - that is a Stinger 120, right? I have one started, but it's off to the side right now and I have not yet bought an engine for it. I figured if I could find a Moki 2.10 that would be a killer choice. Do you now what your all up weight is? As I understand it the fuselage/tail seciton builds up fairly heavy.
