Expert Tips:
To make the setup go easier on transmitters with 5 or more programmable points on the pitch curve, assuming that the 5 points
correspond to low stick, point 1, point 2, point 3 and high stick. Set points 1,2,3 to 50% which will create a flat pitch curve in the center
that will allow you to consistently find 50% pitch near mid stick. After servo direction and centering is completed, return points 1 & 3
back to their default values.
For highly aerobatic flying, when the rotor head speed is at 1500rpm or above, bond the flybar paddles in place using cyanoacrylate
glue to the flybar.
Radio Setup Procedure
1. It is best to choose a new model memory (if available) and use the Reset feature to remove any previous settings or mixes.
Remember this usually also returns the radio configuration to single servo.
2. Locate and activate the swashplate mixing for 120
3. Return both the aileron and elevator trims and subtrims to neutral along with any hover pitch knobs to neutral.
CP setup:
4. Power on the transmitter and the helicopter without the main or tail motors connected. Center collective stick to 50% and find the
correct servo arm that is closest to 90
5. Watch as the collective stick is moved that all three servo arms move in the same direction. Any servo that is moving in the wrong
direction should be corrected using the servo reverse function for that channel. Continue until all three servos work together to move the
swashplate in the same direction.
6. Watch as the collective stick is raised that the swashplate moves upwards. If it moves downwards, go to the ccpm swashplate menu
and change the default setting to be opposite, for example, if Pitch is set to +60 then change to -60 and retest.
7. While looking from the back of the helicopter, check that when the elevator stick is moved forward that the swashplate tips forward
and when the aileron stick is moved left the swashplate tips left. If the swashplate moves in the wrong direction, change the direction
from the same ccpm swashplate menu. Change from the default value of +60 to -60 and retest.
8. Now that the servos are moving in the correct directions, the servo horn must be trimmed using the internal subtrim feature to position
the arm be 90
0
degrees to its pushrod (and to the length of the servo), use the subtrim to achieve this angle, be as precise as possible.
9. Carefully remove the three pushrods from the swashplate and verify the length is 25mm from the "z" bend to the center of the ball link.
Remove each servo horn one at a time and drill the last hole (photo) using a #55 drill bit [1.34mm or 0.052"] that located the pushrod at
11-12mm from the center of the servo arm pivot point.
10. Now that the basic radio setup procedure is completed, return to your pitch curve function and restore points 1 & 3 to their default
valves, usually 25% and 75%. Move the collective stick from low to high and watch the swashplate, if the swashplate bends at the low or
high position, reduce the pitch value in the ccpm menu, for example if the value is -60 try -55 and repeat the test. Continue until the
swashplate moves to the limits but does not bend.
11. Move the cyclic (aileron and elevator) sticks to the full horizontal and diagonal positions and see if the swashplate is binding against
the main shaft. If it does, return to the ccpm menu and reduce the value for the servo that is binding. While holding the cyclic stick in the
corner, slowly rotate the rotor head and again watch the swashplate for binding.
