1. I
NTRODUCTION
PERMAX motors are manufactured to high standards for quality-
conscious modellers. Carefully optimised for low weight, high
efficiency, high torque and durability, PERMAX brushless motors
are the perfect choice as power plants for RC models.

PERMAX BL-2316-1400 brushless motor is designed for use in
3D models with an all-up weight of up to about 300 g, for
aerobatic models weighing up to about 480 g and trainers up to
around 800 g. They also are suitable for powered gliders
weighing up to around 1200 g.

AFETY OTES
• Read the instructions before using the motor for the first time
• Check that the motor and propeller are firmly attached before
every flight
• Do not connect the battery to the speed controller until you
have switched the RC system on, and checked that the throttle
stick is at the "OFF" position
• Never run the motor whilst holding it in your hand
• Do not exceed the stated maximum screw depth when
installing the motor
• Remove all loose, lightweight objects from the area in front of
the propeller before running the motor, as they may be sucked
into the propeller
• Protect the motor from dirt and damp
• Ensure that no foreign bodies get inside the motor
• When the motor is running, do not stand in front of the
propeller plane or in line with it
• Do not exceed the maximum permitted rotational speed of the
motor and propeller

• Stop the motor immediately if you notice vibration, and
eliminate the cause before running it again. You may need to
balance the propeller
• PERMAX brushless motors must never be connected directly
to a power source, as this will wreck the motor
4. O N
PERATING OTES
PERMAX brushless motors must only be run in conjunction with
a sensorless controller for brushless motors. If the motor shaft
spins in the wrong direction, disconnect the battery (to avoid
short-circuits) and swap over any two of the leads between the
motor and the speed controller.
Do not bend the motor leads sharply. Deploy them in such a way
that they are not subjected from vibration and oscillation.
Do not shorten the wires attached to the motor. If you wish to
use different connectors, unsolder the existing ones.
Ensure that the motor and speed controller are adequately
cooled when running. The maximum motor load may only be
used briefly, i.e. no more than fifteen seconds. At the same time
the maximum case temperature of 65° C must not be ex ceeded.
Use properly balanced propellers only, as this avoids vibration
and premature bearing damage.
5. M N
AINTENANCE OTES
Brushless motors are largely maintenance-free, but a little care
will ensure that they last a very long time:
Protect the motor from dust and dirt - especially the ball races.
Soiled bearings may jam, and they will then need to be replaced.
For this reason lubricate the bearings with thin oil at regular
intervals. Do not immerse the motor in water or solvent.
6. T P S
IPS FOR OWER
The selection of the motor and the design of the power system
must reflect the model type, the kind of flying envisaged, the
model aircraft's all-up weight, and its flying speed.
We suggest these basic rules for power system design:
• approx. 100 Watt / kg input power for electric gliders
• approx. 150 Watt / kg for trainer models
• approx. 250 Watt / kg for aerobatic models
• approx. 400 Watt / kg for 3-D aerobatic models
You can calculate the power required if you know the model's
all-up weight and general type. The current drain required is
found by dividing the required input power by the input voltage
available. I [A] = P [W] / U [V]
When calculating the input voltage take 90% of the nominal
battery voltage as the basis: 1.1 Volts for one NiXX cell, and 3.3
Volts for one LiPo cell.
The following diagrams are designed to help you select the
appropriate propeller. The propeller size varies according to the
operating voltage and the calculated current drain.
Please note that an aerobatic model, a 3-D aerobatic type or a
trainer (relatively slow flying, more thrust required) calls for an
entirely different propeller to a model which is to fly very fast.
