OS GT15HZ Petrol Helicopter Engine

The GH15HZ is perfect for sport, 3D and scale pilots alike. But that’s only a part of what makes the GT15 super. It also offers superb fuel economy, a pumped carb to deliver fuel dependably, the ease of the IG-05 Ignition module and smooth running without constant adjustments. And since it’s about the same size as most .90 glow engines, it’s an easy retrofit, too.
