1. GENERAL DESCRIPTION
The Quik is an advanced weight-shift controlled aircraft. It may be flown solo or dual without ballast. The
aircraft has been developed for advanced cross-country touring performance; a stable hands-off cruise of 75
to 80 mph makes long cross-country trips very practicable. Using appropriate airfields and the instructor
control bars, it can also be used as a safe and reliable training machine.
The Quik GT450 was introduced in 2005 with Rotax 912 and 912-S engine options and 1.72m 3 bladed
Warp Drive Propeller. It features a 65L tank, disk or drum brakes and electric trim.
The GT450 is designed for up to 450kg AUW, giving approximately 232kg of payload (fuel, occupants,
baggage). The total maximum seat loading is 220kg, 110kg per seat. The aircraft has been designed with a
wide speed range enabling slow speed flight at very low fuel consumption, short takeoff and landing as well
as cruising speeds up to 95mph. The electric trim system gives precise fingertip control of hands-off trim
speeds from approximately 50 to 80 mph.
A roll augmentation system has been developed for the GT450 wing, which actuates the wing trailing edge
and keel pocket when a roll input is made. The system noticeably lightens roll control. The wing planform and
twist are designed to improve L/D performance. The wing is also equipped with tip fins to improve directional
stability at high speed as well as low speed sink rate and glide. They are vented to control internal wing
pressure.
Both the Quik and Quik GT450 have been designed for easy single-person rigging. The pylon hinges for
folding independently of the engine and undercarriage mountings, which allows for better undercarriage
geometry and structural rigidity.
These features make the aircraft capable in a multitude of roles including long distance touring, competitions
and training.
Optional equipment includes low-drag panniers, a pod bag and instructor control bars.
Do not attempt to act as pilot in command from
the rear seat unless training bars and rear
steering is fitted, and special training has been
undertaken to fly from the rear seat. So
lo flight
from front seat only.

3.0. EMERGENCY PROCEDURES
Engine Failure in Flight
You should always be flying within easy glide distance of a suitable forced landing area, and keep track of
the wind direction. At any stage of your flight you should have your forced landing area selected. If your
engine should stop, the first priority in any engine failure situation is to FLY THE AIRCRAFT. Set up a
steady glide, fly at 45 mph for minimum sink rate and 47mph for best glide. Increase speed to 55 mph for the
final approach.
The second priority is to CONFIRM YOUR SELECTED FORCED LANDING AREA. Be particularly vigilant
for power lines, electric fences, slopes and lee turbulence from obstacles. Determine wind direction from
smoke, water ripples, cloud shadows (remember to mentally calculate for Coriolis effect) or otherwise if there
is time, make a steady 360°turn to determine drift. Refer to your map for altitude above the forced landing
zone. Plan a proper approach into the area, and set up a glide towards it.
With these things in mind, if there is time to attempt a restart, check:
1) Both ignition switches on.
2) Hand throttle closed.
3) Fuel contents ok.
4) Fuel turned on.
5) Choke off unless cold or if suspected fuel starvation.
6) Mixture fully rich
7) Foot throttle no more than 1/4 open.
With the aircraft in a stable hands-off glide, operate the electric starter.
FORCED LANDING DRILL: Throttles SHUT.
Both ignition switches OFF.
Fuel OFF.
Brakes OFF.
Harness secure (do not over tighten pilots shoulder strap).
Plan approach.
Engine-off Landings
The Approach - Quik
The most important part of the approach is the base leg. Aim to start the base leg at approximately 800 feet
agl and set up an approach speed glide of 60-65 mph. It is inadvisable to make the final approach slower
than about 60 mph unless the field is very small, as wind gradient may reduce the airspeed too much and
make the final flare unsuccessful. Gauge the right moment to turn onto finals at 4-500 feet as the base leg
progresses. On finals, quite a lot of glide angle control can be made by varying the airspeed.
The best technique is to maintain 60 mph airspeed through the wind gradient to a low level, say 10 ft, and
then progressively ease the bar out as the speed decays until a smooth touchdown is made.
The Approach - QUIK GT450
The most important part of the approach is the base leg. Aim to start the base leg at approximately 800 feet
agl and set up an approach speed glide of 55-60 mph. Gauge the right moment to turn onto finals at 4-500
feet as the base leg progresses. On finals, quite a lot of glide angle control can be made by varying the
airspeed.
Always be prepared for the engine to fail when it is least convenient and
therefore always ensure that you are within gliding distance of a suitable
emergency landing field. Regular pra
ctice of glide approaches on engine
idle will pay dividends. Warm the engine periodically when doing this.
WARNING
!

Issue 1 Page 18 of 68
The best glide of the GT450 is approximately 8:1 at 50 mph, but this can be reduced to 4:1 at 80 mph. It is
inadvisable to make the final approach slower than about 55 mph unless the field is very small, as wind
gradient may reduce the airspeed too much and make the final flare unsuccessful.
The best technique is to maintain 55-60 mph airspeed through the wind gradient to a low level, say 10 ft, and
then progressively ease the bar out as the speed decays until a smooth touchdown is made.
Engine Failure on Take-Off (see WARNING in Section 7.4)
In order to minimise the potential safety hazard in the event of an engine failure on take-off, never climb-out
at a steep angle when close to the ground (an airspeed of not less than 60 mph is recommended for the first
200ft) and always use an airfield long enough to allow a safe engine off landing straight ahead when the
aircraft is too low to turn into a shortened circuit. Resist the temptation to pull the control bar violently in after
such a power failure as this will produce a steep nose down attitude. Instead, let the bar assume the neutral
trim position until the aircraft regains airspeed and levels out. For minimum height loss, the nose-down
rotation of the aircraft can be checked by pushing out once the nose has dropped below the horizon. The
bar can then be eased in again to take up a glide. From that point, treat the situation as an engine off
landing. Using the trimmer to trim hands-off at the climb speed gives increased pitch damping compared to
using the fast trim setting. Always set trimmer prior to takeoff.
Instrument / electrical Failure
The essential instruments required by the conditions of the Permit to Fly are an altimeter and an airspeed
indicator. Basic engine instruments such as the oil pressure gauge are also essential for flight safety. If these
basic instruments fail, a landing should be made as soon as it is safe to do so. In the case of an over voltage
fault, it may be prudent to turn off the master switch to prevent avionics damage.
Engine Overheating
With a well maintained engine, overheating should not occur. The two basic reasons are weakening of the
fuel/air mixture, and cooling system failure. Condition of the fuel filter, float bowls and the fuel itself are very
important. Check also the radiator, coolant level, condition of hoses.
Fuel starvation may be detected by a sluggishness of the engine to respond to the throttle, a reduction in
RPM, and a change in the exhaust note. If fuel starvation is suspected, then it may be possible to keep the
engine running by pulling out the choke. Reducing the throttle setting may also keep the engine running.
These measures should only be used to fly the aircraft to the nearest safe landing area, where a forced
landing should be planned. If temperatures continue to rise, execute a forced landing as described above.
Fire
If a fire occurs on the ground, then immediately close both throttles, switch OFF the engine and exit the
aircraft, turning OFF the fuel as you go.
A fire in the air is a considerably greater hazard. Two possible causes are electrical or fuel. Smoke or fire at
the front of the aircraft is almost certain to be electrical in origin while occurrence at the rear could be from
either cause.
In the case of an electrical fire, turn OFF all electrical equipment and land as soon as is safely possible.
In the case of a fuel fire, select a landing area, turn OFF the fuel and allow the engine to run until it stops.
Turn OFF the ignition and perform an engine-off landing as described above.
Do not attempt to take off again
without
positively identifying the problem, solving it and
running the engine at take off power for at least
seven minutes.
Only use genuine streamline panniers part YQC-
212. Other panniers can cause overheating.

4. PREPARATION FOR SAFE LSA OPERATION.
4.1. TRAINING
Safety is no accident. The safe operation of an aircraft stems from many factors, but one of the most
important is pilot training. Please ensure that the following conditions always apply:
Qualifications
Before taking command of your Quik or Quik GT450, you must hold a pilot’s licence valid for microlight
aircraft issued by the national or state aviation authority, or be under instruction towards your licence. You
must have gained your licence on flexwing aircraft, or have passed a flexwing alternative controls test to the
satisfaction of a qualified flexwing microlight instructor. The training standards must be at least equivalent to
the BMAA microlight pilot’s syllabus for flexwings.
Type Conversion
Conversion to the Quik or Quik GT450 by a qualified instructor or experienced Quik or Quik GT450 owner is
essential unless you are very experienced on flexwings ( 200+ hours as a guide) and current. First flights
must be in smooth conditions with less than 5kt cross wind and at least 400m clear unobstructed runway.
The Quik and Quik GT450 are easy to fly, but have a very wide trimmable speed range. It is essential that
proper control of speed is exercised for different phases of flight, especially landing approaches.
Currency
If you have not flown within the previous 3 months, take a refresher lesson with a Qualified Instructor before
flying as Pilot in Command, and do not operate the aircraft until the Instructor is satisfied with your ability.
4.2. PRE-FLIGHT PLANNING
Planning is pivotal to the legal safe operation of all aircraft. Please ensure that the following conditions
always apply:
Air Law
Before flight, check that your aircraft documents and pilot qualifications qualify in the states or countries in
which you intend to operate. Air Law can vary from country to country and from state to state; be sure to
always fly within the letter of the Air Law that operates in your state or country. Make sure you have
permission to fly from both your take-off site and your intended landing site.
Weather Conditions
Flexwing Microlights should only be flown in calm conditions. The prudent pilot takes care to avoid flying in
strong winds (more than 15mph), gusty, thermic conditions, crosswinds, rain and any kind of storm. (See
Section 8 for more detailed weather limitations.) Remember also that the weather at your destination may be
different from your starting point, so check before you set off. Detailed aviation weather reports are usually
available from your local airfield, and on the internet. If the weather unexpectedly changes for the worse
during a flight, then the safest option is to land at a suitable landing site at the earliest opportunity.
Route Planning
Plan your route using an appropriate pilot’s map, properly folded and stowed in an appropriate map-holder
which is securely fastened to the pilot/passenger or airframe. Ensure that your planned route remains within
the operational Air Laws of your state/country. Always plan your route so that you fly within safe gliding
distance of a suitable landing area in the event of power loss or complete engine failure. Avoid flying over
mountains or large hills, seas or lakes, built-up areas, woods or forests, deserts with soft sand or anywhere
else that renders a safe landing impossible in the event of an emergency. Remember that there is a greater
risk of turbulence when flying near mountains. Never fly in the lee of hills or mountains if the surface wind is
Do not attempt to operate the aircraft without having carried
out the full training syllabus and having satisfied a qua
lified
instructor/examiner of your competence to do so and having
been issued with a certificate of competency. Without proper
instruction the GT450 aircraft is not safe to operate and
almost certainly will cause injury or death.

anything other than calm, since lee rotor can be extremely dangerous. Always plan for the possibility of
having to divert to an alternate airfield because of bad weather, and make sure you carry enough fuel to
reach your alternate destination with a further 60 minutes of flying time in reserve. Use the advice in this
paragraph in conjunction with that obtained in your formal training. This advice must not be taken as a
substitute for proper training.
Clothing
Both extreme heat and extreme cold can be dangerous to pilot and passenger, since they can affect the
human brain’s decision making process. Please ensure that you wear clothing appropriate to the conditions
in which you fly. Crash helmets, ear defenders, gloves and a purpose-built flight suit should always be worn,
irrespective of the conditions! In bright conditions, high quality unbreakable sunglasses are also a sensible
precaution. Remember that the temperature drops 2-4 degrees F per 1000 feet of altitude, so clearly if your
route demands high altitude flying you should dress appropriately. Remember also that the pilot and
passenger in open cockpit aircraft will suffer from wind chill, which has the effect of making the ambient
temperature seem much lower than it actually is. Finally, check that neither pilot nor passenger has any
objects which can fall out of their pockets since any loose objects are likely to pass through the propeller arc,
destroy the propeller in doing so and seriously threaten the safety of the aircraft and its occupants.
The Payload
The aircraft available payload is the difference between its dry empty weight (see Section 10.2) and its
maximum authorised take off weight (MAUW - see Section 10.3). Before each flight you should calculate the
combined weight of the aircraft, fuel, pilot and passenger and ensure that it never exceeds 990lb (450
kilograms).
Fuel
Before each flight, you should calculate your fuel requirement. (For an approximate fuel consumption guide,
see Section 10; remember that fuel consumption can be affected by many factors including engine condition,
take off weight, density altitude, speed). You should ensure that you have enough fuel and reserve for your
planned flight (See paragraph on Route Planning above) by carrying out a visual check of the fuel level
before you set off and calculating the endurance limit of the aircraft leaving at least a 30% reserve factor.
Never rely only on fuel gauges, use them only in conjunction with your calculated fuel endurance notes.
Check the fuel is of the appropriate quality (see Section 2.2), properly filtered against impurities. Drain a
small quantity of fuel via the drain valve before each flight to check for water.
Human Factors
Before flying, check the Human Factors learnt as part of your flying license. Never fly with a cold, under the
influence of drink or drugs, after an illness/accident without clearance from your Doctor, or when feeling
depressed.
It is extremly dangerous to exceed the 450kg
(990 lb) take off weight limit, it could cause
structural failure or loss of control leading to
injury or death.
Articles of
clothing, such as gloves and scarves that may be taken off in flight, or
glasses/sun-
glasses must be secured by a tie short enough to ensure that they
cannot fall out of the aircraft or be blown into the propeller.
Other objects that are carried in the co
ckpit such as maps, knee boards and other
navigation equipment must be similarly secured.
Occupants with long hair, particularly in the rear seat, must have it tied to ensure
that it cannot reach moving or hot parts of the engine.
Failure to take these precautions could result in injury or death.
