Himax motors are manufactured to high standards for
quality-conscious modellers. Carefully optimised for low
weight, high efficiency, high torque and durability, Himax
out-runners are the perfect choice as power plants for RC
models. Please read right through these instructions before
you use the motor for the first time; this will ensure that you
are able to exploit your motor’s performance to the full.

Himax HC 3528 series motors are substitutes for 600- and 700-
size standard electric motors. They are an excellent choice for
medium-sized model aircraft with an all-up weight of up to 1.6 kg
for 3-D flying, up to 2 kg for aerobatics, and up to 2.5 kg for
normal flying. They are supplied complete with propeller
adaptors, 3.5 mm gold-contact connectors, mounting materials
and matching allen keys.
The graphs printed opposite show the currents for both motor
types at different voltages and with different propellers. For
NiMH and NC batteries use 1.1 Volts per cell and for LiPo packs
3.3 Volts per cell as reference figures. However, the actual
currents in the model will vary considerably according to battery
make and propeller type (rigid or folding). Before flying the
model for the first time it is advisable to measure the motor
current at full-throttle with fully charged batteries, to eliminate the
possibility of overloading the motor or controller.
1. OPERATING NOTES
Himax brushless motors require a sensorless speed controller
for brushless motors. The Phoenix controllers from Castle
Creations are an excellent match, and they are also available
through Multiplex. Their default timing settings are ideal for
Himax motors in model aircraft. Choosing the incorrect controller
can result in the destruction of the motor and speed controller.
You can reverse the direction of rotation of the motor by
swapping over any two of the three motor wires; there is no
need to re-program the speed controller. If the motor spins in the
wrong direction, first disconnect the flight battery - to avoid short-
circuits - and then swap over any two wires between motor and
controller.
Do NOT shorten the wires attached to the motor. Shortening or
cutting off the motor wires may result in motor failure, and also
invalidates the guarantee. If you wish to use connectors other
than the standard ones, unsolder the connectors.
On no account cut off the original 3.5 mm plugs and wires !!
Provide the best possible cooling for the motor and controller
when the model is flying. Without effective cooling, today’s high-
performance batteries may cause motors to overheat, even
when they are not under constant extreme load. Damage
caused by overheating is not covered by the guarantee.
Please do not dismantle the motor, as this also invalidates the
guarantee. Use our Service Department for repairs.
Don’t fit the propeller until you have checked the direction of
motor rotation; ensure that nothing can obstruct the propeller
before you connect the battery. Careless handling of high-
performance power systems can result in serious personal
injury.
