Required to complete:
180 to 250 Newton Turbine: A Jetcat P180 turbine was used in the prototype model and this
provided the minimum power recommended for the Hunter, with a 200 to 220 Newton turbine
giving a perfect balance between power and weight, without requiring too much fuel to be carried, If
a larger and more powerful turbine is to be used it is recommended that full power is not used when
the model is diving, as this may overstress the airframe.
Radio: A 12 to 18 channel radio will be required to allow all the functions of the Hunter to be fully
utilised. Due to the size and weight of the model it is highly recommended that twin receivers and
battery packs are fitted to allow a degree of redundancy in the event of the receiver or battery
failure. Futaba radio equipment and PowerBox Battery/Receiver systems were used in this prototype
with great success.
Servos: The Hunter requires a total of 7 high quality servos for the flying surfaces and a further metal
geared high power servo for nose wheel steering. The prototype model used metal geared Futaba
servos all round – BLS451 servos of 10.6Kg.cm torque for the ailerons, BLS452 servos of 14.0Kg.cm
torque for the elevators and flaps, a BLS155 servo of 18.0Kg.cm for the rudder and a S9450 of
8.0Kg.cm torque for the nosewheel steering
.
Assembly Instructions:
Tail Surfaces:
Remove the elevator servo covers from the tailplane then use a countersink bit in an electric drill to
form neat countersinks in the outer side of the cover, these should be just deep enough to allow the
securing screws to sit flush with the outer surface of the hatch.
Fit the “L” brackets to one of the elevator servos – note that due to the lack of vibration that is a
characteristic of turbine powered models it is normal to mount the servos without the rubber
grommets and ferrules that are required for use in models powered by 2 or 4 stroke I/C engines. This
has the added benefit of making the entire control system more rigid and less prone to damaging
flutter.
