H series Brushlss

A light weight motor that is Strong, Powerful, Versatile & Economy
Ultrafly’s new H/18/xx series brushless sensorless motor is a light weight motor with over whelming power range from 500-1500 watt power. It was designed based on our famous C/xx series. The versatile application covers 3D flying, Park Flyers & helicopters as well as E-conversion a 40-120 class gas power model. The precision CNC tooling with hi-quality material allows this motor to operate at higher RPM without vibrations. The Fan unit at the back of the motor ensure the motor remain at lower temperature in hi-power through put. Quality, Strong and Efficiency are the goal we are shooting for! Versatile is the word best describe its capability!

Cautions

Speed Controller:
	You must use a brushless, sensorless speed controller.

Cooling::

You must provide proper cooling to avoid exceeding the 100-degree-celcius limit. Overheating will damage the magnets and windings, and is not covered under warranty. Proper cooling is necessary when you are trying to use it in larger power (>200 watt) application. In poor air flow applications like Helicopter or boat, you may have to use proper airflow redirection device or power fan to cool the motor or you may result in over heat situation to the motor.

Over current:
	Please use a current meter to control the battery cell count and the propeller size. When changing propeller size, or battery type you must measure the current. You must limit current to the specifications above, or less, to avoid damage to the motor. Reduce prop size or battery cell count to reduce current.

Max input watt:
	For each motor, its structural design will limit its heat dissipation. Watt input is proportional to heat generated. The maximum watt input for F/18 series is 350 watts. Do not exceed this limit or you may easily burn out the motor.

Rotation:
	Switch any two of the three wires between speed controller and motor to reverse motor direction. NEVER reverse polarity from battery to speed controller.

Limited Warranty:

Ultrafly brushless motors have a one-year, limited warranty from date of purchase. All motors are guaranteed to be free from manufacturing defects for one year. The warranty does not cover over-current, over-temperature, or crash damage. The customer must properly cool the motor and keep the current and input wattage within specifications. Improper use of the motor can be determined in service and will not be covered in the warranty.
All warranty issues shall be handled by your dealer first. If necessary, you may also contact us for warranty issues. Send mail to service@ultraflymodel.com or contact the distributor in your country.
