When it comes to gasoline aircraft engines, the GT-33 is in a class of its own. It has the muscle to swing larger props, and it stands out for many other reasons, too. The GT-33 runs more quietly than comparable engines while exceeding their output, and it starts easily with electronic ignition that accepts many battery types. Once again O.S. has produced a gas powerhouse for the serious pilot!For the many planes that use 2-stroke .91 or 4-stroke 1.20 glow engines, the GT22 — the third gasoline engine available from O.S. — is the perfect choice. It cranks out nearly 10% more power than other 2-stroke gas engines of similar size!Throughout the GT22, the fit and finish are outstanding — always delivering the same high performance as when you first installed your brand new, hand-crafted, quality inspected O.S. Engine.
