Background

Desert Aircraft - a revered name in RC gas engines. This one came installed in a Slipstream SBach 342 that I purchased secondhand late in 2012. It's an extremely reliable performer - it doesn't four-stroke, it doesn't deposit oil on the airplane and I have never touches the carb needles. Mated to a canister, it's very quiet. The specified ratio for Redline Racing oil in this engine is 40:1, but my other engines prefer a slightly slicker brew so I switched to 32:1 for everything. Nary a problem.

It was still in the SBach when I sold that plane in 2015.
