JetCat SPT10-RX-H Dual-Exhaust

JetCat SPT10-RX-H two-shaft helicopter turbine

The JetCat SPT10-RX-H converts turbine power into controlled shaft output for demanding model-helicopter installations. The free power turbine is mechanically independent of the core engine and transfers energy through a high-speed reduction gearbox, following the same basic principle used in full-size turboprop and turboshaft systems.

Electronic rotor-speed control

JetCat ECU software for the SPT-H range allows up to three main-rotor speeds to be programmed and selected from the transmitter with a three-position switch. The ECU monitors both shafts and maintains rotor speed during load changes, allowing the pilot to focus on flying rather than engine management.
