The O.S. GT15HZ 2-Stroke petrol helicopter engine is also the first petrol engine designed especially for 90 class engine/ 700 class electric helicopters. With an approximate runtime ratio of 1 minute per 10cc of petrol, it offers astoundingly long flight times and low cost alternative to glow fuel.
Gasoline engine generates larger amount of heat. To prevent overheating, large deep-?nned head is employed which ensures steady power supply by cooling entire engine efficiently.
The Ignition unit has been designed with ignition timing specifically for helicopter engines and features a straight plug cap for easier installation in the limited space. Suitable for use with a 4.8-7.5V battery.
OS test data shows with a 300cc fuel tank you can achieve an approximately 25 minute long flight!
The included compact standard type silencer is suited to compact/sport installations especially in scale helicopters.
