Operation:
1. Himax Brushless motors require brushless sensorless speed controls. Failure to use a brushless sensorless elec-
tronic speed control (ESC) can result in damage to the motor and/or ESC. A Castle Creations Phoenix or Thunderbird
series ESC is recommended for best performance. The standard setting for timing advance is recommended for best
operation.
2. The three wires of the motor can be connected to the three output leads of the ESC in any order. Check the direction of
rotation of the motor. If the motor spins in the wrong direction switching any two of the motor wires will reverse rotation. Be
sure to insulate the wires to prevent shorting which may damage the ESC.
3. If the supplied connectors are not to be used, remove them by desoldering. DO NOT CUT THE CONNECTORS OFF!
4. Allow for proper cooling of the motor during operation. With extremely high capacity batteries, care must be taken to
prevent excessive motor temperature. Overheating of the motor is not covered under warranty. Insufficient cooling can
result in overheated motors, even when operated at moderate power levels.
5. Do not disassemble the motor. Disassembling the motor voids the warranty. If service is required please return the unit
to Maxx Products for service.
6. Install the propeller after proper rotation has been determined. Consult the ESC operation manual for proper arming and
use procedures. Be sure the prop is clear before starting the motor. Once the battery is plugged in stay clear of the prop,
electric motors are capable of extremely high torque and can be very dangerous.

Choosing a power system:
Power system can be chosen based on the type of flying expected of the model and all up weight of the aircraft. Sedate flying
from a hand launch requires 35 watts per pound(W/Lb). Taking off the ground needs approximately 50W/Lb. Aerobatics and
good climb performance, 75W/Lb. Anything more than 75W/Lb will result in excellent performance. Based on the weight of
the model and the flying desired, the power require can be calculated. Select the voltage of the battery being used. It is best
to use a loaded voltage of about 90% of nominal. Now, calculate the current required. From the chart, pick a motor at the
voltage you intend to use and find the prop that will pull the required current.
Typical applications for HC2805-1430:
Current at 9A when used with 2S LiPo and APC 9" x 4.7" SF prop
Current at 6.5A when used with 3S LiPo and APC 6" x 4" E prop
Max. weight of indoor model aircraft: 220 g for 3-D, 420 g for mild aerobatic, 630 g for slow flyer.
Battery: 6 – 11 VDC Lipo or NiCd/NiMH pack
Maintenance:
Brushless motors are almost maintenance free, so minimal care is required for long life. Keep the motor clean free of dust
and dirt, especially the bearings. Dirty bearings wear quickly. Lubricate the bearings regularly with light oil. Do not immerse
the motor in water, or solvents. Do not bend the wires excessively and secure wires to prevent breakage due to fatigue from
vibration. Always used balanced propellers to reduce loads on bearings, to reduce noise, and reduce stress on the airframe.
Be careful to install pinion gears properly. Improperly installed press fit pinion gears can result in damaged bearings, bent
or broken shafts, or broken rotor assemblies. If in doubt, use set screw secured or glue-on type gears to prevent damage.
Warranty:
Himax motors have a two year limited warranty to the original owner, excluding gearboxes. All motors are guaranteed to be
free from manufacturing defects within two years of date of purchase. Not covered under warranty is crash damage,
customer abuse, improper use, or overheating. Warranty claims should be handled directly with Maxx Products, 815
Oakwood Rd, Unit D, Lake Zurich, IL 60047. Please go to our website at www.maxxprod.com and down load the motor
service form. Be sure to include contact information and a description of the problem including which ESC, battery, and prop
was being used.
