RE: Saito 62a vs OS FL 70
True to a point. However, one could have taken the money that the OS .70FL would cost and buy either a Magnum .70 or .91 four-stroke, which had two needle carbs and a rebuildable piston/cylinder setup because they utilized a piston ring.
My airplanes could care less what name is on the side of the engine. They seem to be quite happy with a variety of engines as long as they produce enough power and keep running throughout the flight.
I love OS engines, but those folks at OS live in their own little world. The rest of the engine manufacturers of the world are catching up with them where it counts in initial price, parts cost and durability/longevity.
