Fuel supply
Pay the utmost attention to your tank system! A wrong design causes turbine shutters or flame outs.
Keep suction lines as short and as thick as possible and do not install quick connectors there.
Pressure lines can be equipped with quick connectors, and these cables should also be kept as short
as possible. Pay attention to short and thick vent lines in glasfiber tanks. Always use a felt pendulum
in the main tank. Attention, the felt can be laid by fungi and the pump can reach its performance
limits. Each component of the fuel supply has a flow direction. his is marked with an arrow on the
component. he filter in the fuel system must be installed after the pump and before the turbine to
protect it from contamination. here is no additional filter necessary if hopper tank already has a
filter . For filter in hopper tanks use metal sintering filters with a small resistance . Due the many
years of experience of our test pilots, we recommend only one main tank with an oval shape similar
to an egg and a special soft pendulum tube from the company "Jautsch" with felt pendulum. his
tank system is a good solution for most common jets if no extreme aerobatic flight is performed. If
you use bag tanks, use only fixed glued connections, no quick connectors, they may suck air. Make
sure that your bag tank cannot lie around the felt pendulum and shut off the fuel supply. Festo quick
connectors are not permitted for the suction line. Dirt in the pump supply causes immediate blocking
the fuel pump, especially at brushless pumps. Only use 100% clean fuel . We assume no liability for
faulty turbines, models etc. which are caused by blocked pumps due to polluted fuel. Another good
solution of the tank system is offered by the company "Intairco" with their hopper tanks. It is
mandatory to use 6mm tube lines for the pump suck lines. Do not exceed a maximum length up to
the pendulum of 20 inch. (complete suction line max 20 inch) ry do install the fuel pump in area of
enough cooling air. ake care of right position for the venting. It must be placed in area with enough
excess pressure. Some aircrafts produce a hypotension near the wings or the fuselage.

Power supply
Only use a 3S LiPo battery with a minimum capacity of 3000 mAh for the power supply of the drive
system. he battery must be connected directly to the ECU (do not install a switch in the circuit!).
Connect the landing gear, thrust tube and the engine to ground. Static charges can occur without
grounding, which can cause an ECU reset and stops the engine.

fuels
he following fuels with their respective oil content are intended for the engine:
•Kerosin (Jet- A1) (4%-5% Öl) prefer if possible.
•Petroleum (4%-5% Öl)
•Ultimate oder V-Power Diesel (2-3% Öl)
Winter diesel is not suitable for our turbines as fuel. Use Ultimate or V Power Diesel, only use diesel
from branded petrol stations such as Shell or Aral. Other diesel suppliers often have inferior diesel
with a reduced flash point. his leads to bad running behavior of the turbines or to complete failure.
Use only the special Frank urbine Oil. he use of other types of oil can causes bearing damages. A
warranty on the ball bearings is provided under the prescribed maintenance time of 25 hours.
