The approximate calibration of the fuel tank is as follows:

Before you place any reliance on your fuel gauge, you will need to calibrate the fuel gauge on your particular
aircraft. As is general practice in aviation, you should visually check the fuel tanks to confirm that the
contents match the fuel gauge reading before flying. When flying, use your watch to time the flight against
known fuel burn at a given rpm, and always leave plenty of fuel in reserve.
Propeller - Warp Drive.
The condition and torque settings of the 8mm propeller bolts should checked with the frequency
recommended in the inspection schedules laid out below. Torque should be applied by progressively
tightening all the 8mm bolts to 20Nm (15 ft lbs) in the following sequence :
1 - 4 - 2 - 5 - 3 – 6
All 12 ¼” unf bolts should be tightened equally to 12Nm ( 10 ft lb)
Other general maintenance should include replacing any leading edge tape as required by inspection and
regular wiping off of the propeller with a damp cloth to remove insect and other foreign body build-up. If left
unchecked, both the condition of the tape and particle build-up can significantly reduce propeller efficiency.
If propeller leading edge tape is replaced (or added), or if any undue vibration has been noticed, or if a blade
has been chipped and in any case at the recommended service intervals not to exceed 25 hours (see engine
handbook) it is essential to remove the propeller and check the balance. A propeller balancing service tool
kit is available from your dealer.
Do not push the aircraft by its propeller blades, or otherwise bend the blades, which could cause serious
structural damage to the propeller.
Propeller Pitch Setting
For the correct pitch setting for each model, refer to Section 3.4. Refer to the propeller manufacturer’s pitch
setting instructions. Uneven pitch settings can cause vibration, loss of thrust and even internal damage to
the engine. Incorrect pitch setting will affect performance and void the noise certification.
After resetting the pitch, check for tracking alignment, balance, and static RPM as indicated in the table
below.

Never rely on the fuel gauge accuracy alone
when calculating flight distances left to run. A
forced landing due to running out of fuel could
result in injury or death.
WARNING
GG
!
Never fly with a damaged propeller. Damage to a composite propeller could be
structural with little external sign. If a propeller blade “lets go” at cruise power
settings, you have less than 2 seconds before the engine tears itself off its
mountings. Shut the engine down immediately if the propeller gets damaged in
flight or on take-off.
