12.3. TRIKE
General
The Quik-GTR trike has been designed to permit easy inspection and operators should have no difficulty in
assessing problems or recognising damage if visual checks are carried out conscientiously. The trike may be
transported and stored fully assembled or folded down. If folded down, for transport -
a) The pylon must be supported to prevent damage to the structure.
b)
A 64mm wide (21/2”) spacer block must be inserted where the pylon fits into the engine mount.
General care should include:
Washing down the tube work and composite parts with warm water and a light detergent followed by
rinsing with fresh water.
Fabric sponged with warm water and a mild detergent and rinsed with fresh water.
The pod and wheel spatfins washed and polished using commercially obtainable shampoos and
polishes.
The cockpit area should have all litter removed.
Winter storage: if the trike is unlikely to used for some time, lightly spray all mild steel parts with
Duck Oil or similar to prevent corrosion. Spray the engine with WD40 or Silicone Spray.

Fo
r engine maintenance details see Engine Manufacturer’s Manual.
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.
Re-tighten the bolts at the root of each blade to 6 ft lbs and re-tighten the main mounting bolts as described
above. After resetting the pitch, check for tracking alignment, balance, and static RPM as indicated in the table
below.

Never fly with a damaged propeller. Damage to a composite propeller could be
structural wi
th 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.
