Turbine RC Helicopters for Sale: Engines, Costs and What to Know Before Buying
Turbine RC helicopters use small gas turbines that drive the rotor through a reduction gearbox, burning kerosene or Jet-A. JetCat, for example, makes the PHT3 helicopter turbine (about 5.5 kW, 3.45–3.67 kg with gearbox) and the SPT5-H (6 kW, 2.48 kg). They’re fitted to large scale helicopters, often 1:5 or larger, where the real turbine whine and long flight times matter. They’re the most expensive way to fly RC helicopters, and most are sold used or built to order, not off the shelf.

How a turbine helicopter works
A model shaft turbine has a gas generator (compressor, combustion chamber, turbine) and a free power turbine that turns an output shaft. The output runs through a gearbox to the main rotor and tail drive. An ECU manages start-up, fuel flow and temperatures, and the helicopter’s governor keeps head speed constant. Start-up is automatic: the ECU spins the turbine with a starter, lights it and brings it to idle before the pilot engages the rotor.
Buying new or used
New turbine helicopters are usually assembled from a scale fuselage, mechanics designed for turbines, and the turbine itself, often by specialist dealers. The cost runs to many thousands, which is why many pilots buy used. A used turbine helicopter needs its turbine service history checked: turbines have service intervals measured in running hours, and the maker or an authorised service centre should confirm its condition. Ask for ECU logs, flight records and a demonstration flight before buying.
Checklist for a used turbine heli
- Turbine running hours and last service date.
- ECU data and error logs.
- Gearbox condition and oil.
- Fuselage cracks near mounts and exhaust.
- Heat damage around the exhaust.
- Electronics age: servos, receiver, power supply.
- Spare parts and paperwork included.
Training and rules
Many countries and clubs require a turbine certificate or proof of competence before you can fly turbine models, and insurance may depend on it. Heavy models may need additional approvals. Learn on electric or petrol scale helicopters first, and get help from an experienced turbine pilot for the first runs.
Running costs
Fuel (kerosene or Jet-A with turbine oil) is relatively cheap per flight, but service intervals, starter batteries, and parts make turbine flying expensive overall. A crash can cost as much as a car. Compare with petrol helicopters, which give long flights at lower cost; see gas powered RC helicopters.
Safety
- Carry a CO₂ fire extinguisher at every session.
- Keep spectators well away during start-up and flight.
- Store fuel in approved containers.
- Follow the ECU’s start sequence and never override safety limits.
- Check the exhaust and heat shields before each flight.
Where to see them
Large scale helicopter meetings and model shows often feature turbine helicopters. Talking to owners there is the best way to learn about real costs, reliability and dealers. Some of the largest RC helicopters ever built are turbine powered; see the world’s biggest RC helicopters.
FAQ
How much does a turbine RC helicopter cost?
Many thousands complete; the turbine alone is a major part.

Kerosene or Jet-A mixed with turbine oil.
Do I need a licence?
Often a turbine certificate and insurance, depending on country and club.
Who makes helicopter turbines?
JetCat is one maker, with the PHT3 and SPT5-H.
