Flight Controls - Merlin pilot 500 Instruction Manual

Flight Controls

Using the Motor
The motor is used to control the flying speed and rate of climb of the aeroplane
• Initial take off and climb to minimum altitude is carried out at full power.
• To achieve and maintain a level "cruising" altitude, reduce the power by moving the throttle stick down to approximately 70% of full on.
The throttle stick is proportional, so you can add or reduce throttle in small increments as needed to maintain the altitude that you desire.
•
To reduce altitude you need to reduce the throttle, and to increase altitude you need to increase the throttle
Using the Elevator
The elevator is used to control the pitch (level) of the aeroplane. In normal flight small adjustments of the elevator are used to maintain even level
flight.
•
Pushing forwards on the elevator stick makes the nose lower and the speed to increase entering a dive.
•
Pulling back on the stick provides up elevator making the nose rise and flight speed slow. Pulling too far back on the elevator and climbing
too quickly will cause the aeroplane stall. To avoid crashing from a stall, always maintain enough altitude to recover. Just after a stall has
occurred, the nose of the aeroplane will fall and the aeroplane will look like it is diving. To pull out of a stall, simply pull back slowly on the
elevator stick until level flight is resumed. Pulling back too quickly or for too long will once again cause the aeroplane to enter a stall.
Using the Rudder
The rudder is used to control the turning of your aircraft in the air or when taxiing on the ground. The Transmitter control inputs for the rudder are
correct when looking at the aircraft from the tail end with the nose pointing away from you. Left control input will make the aircraft go left and right
control input will go right, when looking from this view. If the model is flying towards you these inputs are reversed. Always use small control inputs
and do not hold rudder for to long. Combining rudder and elevator control inputs will allow for tighter turns
Pre-Flight Checklist and Control Test
Each time before you start flying your Merlin Flight Product please carry out the following check checks and test.
Checklist
• Control surfaces have free movement
•
All screws, bolts, etc. are tight
•
Radio equipment is securely fastened inside fuselage
•
Batteries are fully charged
•
No wires interfere with servo motors
• Wings are securely fastened
• Looking from the rear of the aeroplane to the front make sure that the wings and tail are not damaged and are correctly aligned to the
fuselage.
Control Test
•
Be certain that the throttle stick is in the "off" position. - 000
•
Switch on the transmitter, make sure the aerial is upright and check to make sure the Power indicator is full. If the indicator is empty and
flashing then the transmitter batteries are low on power and must be replaced before flying.
• Plug in the aircraft battery and wait for the receiver power light to stop flashing to confirm the unit has calibrated.
•
Place your model on the ground and walk away whilst operating the control stick.
•
Check that the servos operate without interference up to a distance of 30 metres.
•
Gently move the throttle stick forwards to check the propeller rotates.
• If the control functions do not work to your commands at 30 meters, do not attempt to fly your aeroplane and refer instead to the
troubleshooting section of this manual.
