Instruction
Thank you for purchasing the “QUICRUN-2435, QUICRUN-3656, QUICRUN-4074” brushless motor(s) for RC cars! The high power system
can be very dangerous, so please read this manual carefully before using and strictly follow the operating procedures in use. In that we have
no control over the installation, use and maintenance of this product, no liability shall be assumed nor accepted for damages, losses or costs
resulting from the use of this product. Besides, we own the right to change the product design, appearance, functions and operational
requirements without any notifications.
Safety Notes
This product is not a toy and it is for use by adults and teens over 14 only, so please keep it out of children’s reach.
Please keep the following points in mind; otherwise it may damage the product and cause property loss and physical injuries to
users.
1. Never leave this product unsupervised when it is powered on. If any problem occurs, the product may cause a fire and jeopardize
peripheral devices.
2. Please insure all the wires and interconnecting pieces are well insulated before the connection, as short circuits may damage the
product.
3. Please read through manuals of each power equipment (like ESC, motor, battery, etc) and chassis to ensure the power system
configuration is rational before the use, as the incorrect power system configuration may result in overload and eventually damage the
equipments.
4. Prohibit the full throttle operation before installing the pinion. Under non-loaded circumstances, over-high RPM may cause damage to
the motor.
5. Make sure all the parts are well connected, as misconnection or poor connection may lead to abnormal control, damage or other
unpredictable problems.
6. Never let the temperature of the motor can (shell) exceeds 90℃ (194℉), otherwise the motor will be damaged and the rotor will be
demagnetized.
Installation & Connection
1. To Install the Motor
1) Three types of screws used for installation: M2.6 (diameter=2.6) and M3 (diameter=3.0) for Motor 2435 (this motor has 3 pairs of screw
holes on the front end bell, 2 pairs are 2.6mm in diameter, and 1 pair is 3.0mm in diameter); M3 (diameter=3.0mm) for Motor 3656/4074.
2) Depth of screw holes: QUICRUN-2435<=4mm, QUICRUN-3656<=5mm, QUICRUN-4074<=7mm.
3) Before mounting the motor onto the vehicle, please ensure that all the screws are applicable to avoid damaging the motor. In general it’s
ok to use screws, 2.6mm or 3mm in diameter (M2.6/M3) and less than 6mm in length, to install motor QUICRUN-2435; 3mm in diameter
(M3) and shorter than 8mm in length for installing motor QUICRUN-3656; 3mm in diameter (M3) and less than 10mm in length for
mounting motor QUICRUN-4074; and the specific length is up to the respective chassis size.
2. To Connect the Motor
Three power wires need to be connected to the motor, and they often differ in colors: Phase wire A is Blue, Phase wire B is Yellow and
Phase wire C is Orange. Please note the ESC mark while connecting ESC output wires to motor power wires and ensure connections
are: A-A, B-B and C-C.
Note 1: As definitions of triple-phase (#A/#B/#C) are different among manufacturers, connect the motor and the ESC according to the
above method may cause the motor rotates in the opposite direction, at this time you only need to swap any of two wire connections.
3. Checkup
Recheck the installation and all the connections carefully before turning on the power.

Note 2: (Resist. = Resistance, M.O.P = Maximum Output Power)
1) The maximum output power is the test value obtained when the voltage is 7.4V for motor QUICRUN-2435 & motor QUICRUN-3656, and
22.2V for motor QUICRUN-4074, the ESC timing is set to 0°. It is neither the maximum input power nor the rated power. The calculation
formula used here is: RPM x Torque / 9550.
2) The value of the maximum output power is always lower than the value of the input power. Therefore, it’s meaningless to compare the
maximum output power mentioned in the form above with the input power of motors of other brands. Besides, values in the form above
may differ from the test data of other factories because of different test benches.
3) The input current at the point of the maximum output power is useful for the load configuration and the ESC selection; here we strongly
suggest users not make the load quota bigger than the “maximum output power point”, that means please don’t make the input current
larger than the current at the maximum output power point.
Gear Selection (IMPORTANT!)
It is very important to select the reasonable gear ratio, as inappropriate selection may cause great loss to users.
Please select the correct gear ratio according to the following points!
1. Operating Temperature of the Motor
During the operation, the motor temperature should be lower than 90℃ (194℉). Temperatures above 90℃ will demagnetize the
magnet & may melt the coils and eventually damage the ESC (because of strong current). Therefore, the most effective way to prevent
over-heat is to select the right gear ratio.
2. Principle of Gear Selection
To avoid potential risks, caused by overheating, which may lead to ESC/motor damage or malfunction, please start with very small
pinion and check ESC & motor temperatures frequently throughout a run. This is the only way to guarantee that you are not causing
excessive heating. If Motor and the ESC temperatures remain stable and low in the running, then you can slowly increase the pinion
(with more teeth) while again monitoring the temperatures to determine the safe gearing for your vehicle and motor. Because the climate
and track conditions always change, please keep monitoring ESC & motor temperatures to protect your electronics from damage.
Maintenance
For prolonging the motor life and raising its efficiency, we recommend users to check the bearing, and clean the motor regularly; and the
specific interval depends on the usage frequency and terrains. Please follow the assembly diagram (of motor QUICRUN-4074) below to
assemble the motor, and disassemble in reserve order.
Note 3: Because of different craftsmanship, neither QUICRUN-2435 nor QUICRUN-3656 is rebuildable or tunable. Please do not try to
dismantle these 2 motors.
