The O.S. GT60 gives fliers of 50 cc models everything they want in a gasoline engine — durability, efficiency, easy operation and super-strong performance. The GT60's liner-less cylinder construction lowers weight, improves cooling and increases exhaust scavenging efficiency. Intake and exhaust timing are perfected as well. Instant throttle response makes this an outstanding choice for 3D flying. When you need more power ASAP, the GT60 delivers!

• IG-02 electronic ignition system offers quick starts and accepts 4-6 cell NiCd/NiMH or 2-cell LiFe/LiPo batteries.

• Rear-mounted Walbro carburetor is custom-designed for the GT60 — choke rod guide integrated into the crankcase allows effortless set-up.

• Pitts-style E-6020 muffler (optional) features anti-crush tubes for the mounting bolts and webbing reinforcements at high-stress points.

• Includes electronic ignition module and CM-6 spark plug. GT60 with muffler also comes with gasket and bolts.
