A good turbine day starts before fuel goes into the airplane. The model, support equipment, fire equipment, batteries, radio, and operating area all need to be ready before the start sequence begins.
The exact button pushes, limits, and start sequence still come from the turbine manual. What I am laying out here is the field routine around that sequence—the equipment, clear area, fire preparation, checks, cooldown, and first-flight planning that are easy to miss when everyone is focused on the turbine.
Field equipment
- Correct turbine fuel and approved fueling container
- Fuel pump, filtered fill system, and plugs or valves
- Charged ECU, receiver, transmitter, and accessory batteries
- Suitable fire extinguisher required by the site or program
- Restraint appropriate for the model and available helpers
- Tools for cowl, hatch, wheel, brake, and turbine access
- Spare fuel-system plugs, tubing, fittings, and cleaning supplies
- Turbine manual, ECU display or programming device, and aircraft checklist
Choose the operating area
Point the exhaust toward a clear area that cannot be damaged by heat or blast. Keep people, dry grass, loose objects, clothing, tools, and fuel containers away from the intake and exhaust. Use a helper or spotter and follow the field’s turbine procedures.
Before startup
- Inspect the turbine mount, thrust tube, intake, exhaust, fuel lines, filters, wiring, batteries, and hatches.
- Check the airplane’s CG, control surfaces, gear, brakes, steering, and failsafe.
- Confirm the fuel system is filled and vented according to the manual without leaks or trapped air.
- Verify the ECU recognizes the correct throttle positions and reports normal status.
- Place the extinguisher where the helper can reach it immediately.
- Clear the area and announce the start.
During the automatic start
Watch the airplane, not only the ECU display. Listen for an abnormal start and watch the exhaust area. Be prepared to command a shutdown if fuel appears where it should not, the exhaust shows an abnormal flame, the starter behaves incorrectly, temperatures rise improperly, or the turbine does not follow its normal sequence.
Do not stand directly in line with the intake or exhaust. Keep hands, tools, cords, and loose clothing clear.
At idle and during the ground run
- Confirm stable idle, normal temperature, and expected ECU indications.
- Check for fuel leaks, bubbles, unusual vibration, rubbing, or loose equipment.
- Verify steering and brakes before increasing thrust.
- Advance and reduce throttle deliberately while accounting for turbine lag.
- Do not perform long high-power runs unless the procedure requires them.
- Reinspect the model after the first heat cycle.
Shutdown and cooldown
Use the turbine manufacturer’s shutdown command. Allow the ECU to complete its fuel cutoff and cooldown sequence. Do not disconnect turbine power early unless the manual or an emergency procedure specifically calls for it.
After shutdown, treat the exhaust, thrust tube, and surrounding structure as hot. Keep the model in a clear area and wait before refueling or opening enclosed equipment bays.
First-flight preparation
- Installation inspected by an experienced turbine pilot
- Ground runs completed without unexplained warnings or leaks
- Failsafe and range test passed
- Gear, doors, brakes, steering, and retract pressure checked
- Fuel quantity and expected flight time established conservatively
- Takeoff, gear operation, pattern, landing, go-around, and emergency plan discussed
- Runway length, wind, spectators, and fire readiness acceptable
For an unfamiliar turbine model, using an experienced pilot for the maiden and setup flights is a smart decision. I had Ali Machinchy handle the maiden and Synapse setup flights on my MB-339, which gave me a known-good starting point for the airplane.
After each early flight
Review ECU information and telemetry, inspect the fuel system and filters, check the turbine and thrust tube mounts, look for heat damage, and verify nothing has shifted. Record fuel use and flight time instead of guessing how much reserve remains.
Waiver and training
In the United States, pilots flying under the AMA program should follow the current turbine program and waiver requirements. The current AMA Fixed-Wing Turbine Waiver Qualification Guide and application is the authority. Requirements can change, so verify the current documents and work directly with experienced turbine pilots.
For installation planning, use the RC turbine installation guide. Return to the RC Turbine Engines beginner’s overview for the full introduction and waiver overview.
