Place the fuel tank in order to minimize vibrate while elastically stored and unable to relax or
chafe the fasteners. Note that a fully fueled tank is probably (after the engine), the second
heaviest part of the onboard equipment model. How to assemble concrete tank, etc. is
described in the manual tank, we would just like to point ventilation of tank - be careful way it
is conducted and where it opens out! It can also occur in-flight fuel leak eg. to exhaust and
then it can be a problem. Fuel system generally pay maximum attention both in terms of
reliability and safety terms. Use a hose directly related to petrol! Others quickly be harden
during operation and the risk of fuel leakage. Proven yellow tubes are called Tygon.
Furthermore, they are transparent, which is useful for monitoring whether possibly not in the
fuel system bubbles.
Ignition system
When placing the ignition, keep in mind mainly two things: ignition is fully electronic and
vibration did not need to do well and can be a source of interference for on-board system
management model.
Therefore, the ignition is placed at a suitable position (with regard to the length of high-
voltage cables to candles), but away from the receiver and wiring related to the management
model. Applying a similar saving is recommended to receiver - ie. Use for unit ignition
flexible rubber. Great attention should be paid to the management of the ignition voltage
cables to candles. Voltage in the cable may be closer to 20,000 volts. We never kink the
cable into sharp bends, will enable him, if possible, a gradual bend, in many places it we
attach to the solid parts to avoid abrasion by vibration. In exposed areas or in areas where
cable is more thermally stressed it can give more protection to the coil or coated with silicone
tubing.
Change the spark plugs by the engine type rrecomendation. Use prescribed candles and
candle while checking the focus on color and distance spark plug electrodes. At the same
time check whether there is a partial burning of some of the electrodes. Proper candle in a
properly tuned engine should not be black, better brown and no visible carbon. Condition
candles assessed after longer flights in the normal speed range, not e.g. after prolonged idle
- then each candle be black. In case of any doubt, replace the spark plug. In multi-cylinder
engines always change all the candles at once !!!
