Speed Controller for Hornet CP Brushless Electric Motor
Instruction Manual
Dear Customer,
Thank you for purchasing this genuine MS Composit Speed Controller MS - 016, designed specifically for
the Hornet CP brushless motor MS-001.
Mode of operation
The MS-016 Speed Controller has two modes of operation, which are selected in the Programming Mode:
Linear Mode
Standard linear throttle control over the whole range of the throttle stick.
Constant RPM Mode
The RPM is set by a free linear (or rotary) control on the transmitter and the Speed Controller holds
the RPM at a constant speed - regardless of the actual pitch setting. This means no throttle settings are
needed on the transmitter.
Programming Mode
Allows the Speed Controller to be setup for Linear or Constant RPM Modes.
The Speed Controller does not have a brake function as it is not required helicopters.
All the Speed Controller settings are stored in the Controller‘s memory and don’t need to be re-programmed
each each time the power is turned off.
Installation
The power input lead is fitted with a standard (AMP) connector, as used on Hornet helicopters, and is protected
from reverse polarity connection. There are motor power wires. There is no specific order in which the wires
should be soldered to the motor terminals. However, should you require the motor’s rotation to be reversed
(clockwise to anti-clockwise or vice versa), simply switch any two of the power wires.
For Linear Mode operation, connect the receiver lead to the throttle channel.
For Constant RPM Mode, connect the receiver lead to channel 5 or 7 – depending on Transmitter you are
using, then assign this channel to a free proportional control, such as a rotary knob or slider.
Controller programming
The Programming mode is entered if the throttle stick - or the free proportional channel if using Constant RPM
Mode - is set to its maximum position, then controller is switched on. A short tune plays to confirm that the
Programming Mode has been entered. Move the stick (or free channel) to its minimum position, and one or
two short beeps will follow.
The number of beeps indicates the current operating Mode: – One beep for Linear Mode 1 and two beeps for
Constant RPM Mode.
Note: The Controller Mode changes EACH TIME THE PROGRAMMING MODE IS ENTERED!
If the controller is in Linear Mode and the Programming mode is entered, the Mode is automatically
switched to constant RPM Mode and vice versa.
Controller Usage
The Mode of the Controller is indicated after switching on (with the throttle stick or slider at its minimum
position) by the number of beeps. The beeps also indicate that the Controller is ready for operation.
In Linear Mode, the operation is the same as any conventional or brushless motor.
In constant RPM Mode, you must take into account that the change of the rotor speed during the flight can lead
to situations where the accu is unable to deliver the power requirements (especially as they run down), which
can lead to the motor stopping. Therefore we recommend setting the RPM in Constant RPM Mode only when
the model is on the ground – not in the air.
WARNING!
If you reverse the polarity on the power input wires to the Controller, it will lead to irrepairable damage.
Shortcutting the motor power cables will also damage the Controller!
Prolonged overload of the Controller may cause the Controller to automatically cut-off without warning –
often causing a crash.
