To set rates on the elevator and aileron, check to see that the
control rates are set to maximum for high rates. This can be
verified by checking that the ball link attached to the seesaw is
close to touching the main rotor grips at full input. Check the
elevator rate with the flybar perpendicular to the tailboom, and
check the aileron rate with the flybar parallel to the tailboom.
These maximum deflections work well for high rates, and we
recommend 60% of these values for low rates.
Rudder control throw will be affected by your gyro settings,
and will need to be tuned to suit your flying style.

1. Apply the two different colored stripe decals to the tips
of your main rotor blades.
❏
2. At zero pitch, bring the main rotor up to speed and
observe whether the rotational planes of the blades are the
same. If they are not, adjust one of the linkages to bring the
blades into the same plane.
Ground check the operational range of your radio before the
first flight of the day. With the transmitter antenna collapsed and
the receiver and transmitter on, you should be able to walk at
least 50 feet away from the model and still have control. Have
an assistant stand by your model and, while you work the
controls, tell you what the servos are doing. Repeat this test
with the motor running at various speeds. If the control
surfaces do not respond correctly, do not fly! Find and correct
the problem first. Look for loose servo connections or broken
wires, corroded wires on old servo connectors, poor solder
joints in your battery pack or a defective cell, or a damaged
receiver crystal from a previous crash.
Failure to follow these safety precautions may result in
severe injury to yourself and others.
Keep your face and body as well as all spectators away from
the plane of rotation of the rotors whenever the battery
is connected.
Keep these items away from the rotors: loose clothing, shirt
sleeves, ties, scarfs, long hair or loose objects such as
pencils or screwdrivers that may fall out of shirt or jacket
pockets into the rotors.
The spinning blades of a model helicopter can cause
serious injury. When choosing a flying site for your MX450,
stay clear of buildings, trees and power lines. AVOID flying
in or near crowded areas. DO NOT fly close to people,
children or pets. Maintain a safe pilot-to-helicopter distance
while flying.
