SAB Goblin Black Nitro with OS 105 and power boost pipe
Nitro helicopters enter a new dimension with the Goblin.
High center of gravity with an optimized 650 mm blades rotor give the helicopter extreme agility and amazing performance, which is incredible for a nitro machine!
In addition to the flight characteristics, we have paid special attention to making all maintenance work quick and easy. The SAB modular concept allows you to remove the engine unit and the tank in just a few minutes.

The center of gravity is one of the most essential items to a nitro model. We made it a priority to have a high and neutral center of gravity. The fuel tank is located in the center of the main shaft so that as the fuel level changes, the center of gravity remains the same.
The engine and all of its components are in one modular design. With 4 bolts, you can easily remove and install the entire engine assembly from the model.
Starting assembly, clutch stack, fan and motor pulley are installed on one shaft that is directly mounted onto the engine itself. This assures that everything with the engine is perfectly aligned for smooth transmission.

OS 105 Specifications
This is the engine that precision aerobatic and 3D heli pilots have been waiting for! In order for 90-sized machines to nail huge maneuvers and hardcore, smackdown-style 3D it's all about power, and the 105HZ-R has it in abundance. Displacement has been increased by 15%, while a huge venturi rams air into the carburetor, producing massive power. Plus, they fit in a .90-sized mounting pattern.

●Featuring the displacement of a 1.05 in the mounting space of a .90.
●More displacement means more power, and these engines boost displacement by 15%!
●A huge venturi boosts output even further.
●The machined, blue anodized heatsink head is light in weight, and cools the engine efficiently.
●An extra feature on the 105HZ-R is the pressurized DRS (Demand Regulator System), which ensures consistent fuel flow regardless of the heli's attitude.
