Tail Rotor Proportional Mix Trimmer Pot Adjustment - Blade SR Bedienungsanleitung

If the helicopter is drifting forward or backward, you will need to adjust the elevator trim.
If the helicopter is drifting to the left or right, you will need to adjust the aileron trim.
Continue to make trim adjustments until the helicopter can hover at a low altitude with very little drifting and directional
control input. If the Blade SR is your first single-rotor and/or collective pitch helicopter model, it may be best to have an
experienced helicopter pilot trim the model for you before making your first flight.
Note: You can use the throttle trim to adjust the throttle and collective pitch values for a given throttle stick position. For
example, raising the throttle trim will allow the model to hover at a lower throttle stick position.
• Once you have the Blade SR properly trimmed and maintaining a stable low-level hover, practice using the rudder,
elevator and aileron controls to get a feel for how the helicopter responds to control inputs. Remember to keep the
control inputs as minimal as possible to prevent over-controlling the helicopter, especially when in hover.
• When comfortable with hovering the Blade SR at low-levels of altitude just a few inches off the ground, you can
transition to hovering and flying the helicopter at higher altitudes of approximately three to four feet. At these higher
altitudes you will be able to get a feel for the flight characteristics of the helicopter when it is flying out of
"ground effect."
• Don't be afraid to set the helicopter down on the ground quickly by lowering the throttle when approaching obstacles
to help prevent main rotor blade strikes. Also, the optional training gear set will help to further prevent damage to the
helicopter in the event that you must make an abrupt landing to avoid walls or other obstacles when it is installed.
• If at any time during flight you feel like the helicopter is drifting out of control, it is best to return all controls to neutral
and to lower the throttle stick and trim completely or to activate throttle hold. This will help to reduce the amount of
damage that may be caused in the event of a crash.
• IN THE UNFORTUNATE EVENT OF A CRASH OR ROTOR BLADE STRIKE, NO MATTER HOW MINOR OR MAJOR, YOU MUST
LOWER BOTH THE THROTTLE (LEFT-HAND) STICK AND THROTTLE TRIM TO THEIR LOWEST POSSIBLE POSITION (WHEN
IN THE NORMAL FLIGHT MODE) AS QUICKLY AS POSSIBLE TO PREVENT DAMAGE TO THE ESCs OF THE 2-IN-1 UNIT.
YOU CAN ALSO ACTIVATE THROTTLE HOLD IN ANY FLIGHT MODE, REGARDLESS OF THROTTLE STICK POSITION.
Failure to lower both the throttle stick and throttle trim to their lowest possible positions (in the normal flight mode only)
or to activate throttle hold (in any flight mode) in the event of a crash could result in damage to the ESCs in the 2-in-1
unit, which may require replacement of the 2-in-1 unit.
While the 2-in-1 control unit main motor and tail motor ESCs are readily capable of handling all in-flight power loads, and
even brief momentary bursts beyond these typical loads, they can be damaged if excessive amounts of current are
pulled through them for an extended period of time. This period of time may vary depending on many conditions, so it is
best to keep any momentary overloads as short as possible in order to prevent damage to the 2-in-1 ESCs.
Note: Crash damage is not covered under warranty.
• It is extremely important when hovering and flying the Blade SR to be aware of the power level of the Li-Po battery pack.
If at any time the helicopter begins to require more throttle than typical to maintain hover or flight, or has lost the ability
to maintain hover or flight due to significant loss of power, land the helicopter and power the motors down
IMMEDIATELY to prevent over-discharge of the Li-Po battery pack.
If you continue to run the motors after noticing a loss in power it is possible to discharge the Li-Po battery pack too far,
causing permanent damage to the pack. Over-discharge of the Li-Po battery pack can result in shortened flight times,
loss of power output or failure of the pack entirely.

Tail Rotor Proportional Mix Trimmer Pot Adjustment

After trimming the primary flight controls and becoming familiar with the handling of the model, you may also need
to adjust the tail rotor proportional mixing. The proportional trimmer pot adjusts the amount of tail motor to main
motor mixing.
After establishing a stable hover, quickly advance the throttle/collective stick upward to "pop" the helicopter up a few feet in
altitude while adding no rudder input. During the abrupt increase in altitude, note which direction the nose of the helicopter
may yaw/turn. If the nose of the helicopter does not yaw in either direction by a significant amount, no adjustment is
necessary. However, if the nose of the helicopter yaws to the left, you will want to increase the amount of tail motor to main
motor mixing. By turning the proportional trimmer pot clockwise (+), you increase the tail motor/rotor rpm for a given main
motor/rotor rpm. This increase in tail motor/rotor rpm will help to push the nose of the helicopter to the right when there is
an abrupt change in torque.
If the nose of the helicopter tries to yaw to the right, decrease the tail rotor proportional mix by turning the proportional
trimmer pot counterclockwise (-).
Note: You must always power down the 2-in-1 control unit before making adjustments to the proportional mix trimmer
pot. Any changes made to the trimmer pot will not take effect until the 2-in-1 unit is rearmed.
