2 models mostly used in Turbine world 608 ZC AND 602 ZC Modern RC jets use turbine engines. Inside the engine is a single shaft and two hybrid bearings connected to a compressor rotor on one end and a turbine rotor on the other. These bearings have an RPM rating of roughly 30,000 to 140,000 RPMs. To cool the bearings during operation, they must be sprayed with an oil mist. The bearings should be changed after 6-7 runs to prevent bearing fatigue If you not sure which model you really need, please advise with us |
