True to scale sound impression, in some places too loud | Discreet sound, blade flapping can be heard |
Cost is 4000 - 6000 € approx fort he turbine | Cost is 1500 € approx (motor and controler) |
Additonally required equipment: fuel station (200 €), Kerosene, fuel tanks, valves, tubing | Additonally required equipment: charger, power supply, lipo batteries (another 1000 €) |
Kerosene can be difficult to get in some areas | Lipo batteries have a risk to burn |
Kerosene smell can be a problem in cars | - |
Higher virbation level in the model | - |
Thrust influences the flight characteristics | - |
Model loses weight during flight (burnt kerosene) and changes sometimes center of gravity | - |
More know how required (starting procedure, kerosene supply in the model by fuel tanks,…) | |
