E-flite Power 32 Brushless Outrunner Motor, 770Kv - Manual

Power 32 Brushless Outrunner Instructions
The Power 32 is designed to deliver clean and quiet power for 30- to 36-size sport and scale airplanes weighing 3.5- to 6-pounds (1.6- to 2.7-kilograms) 25-to
36-size 3D airplanes up to 4.5-pounds (2-kilograms), or models requiring up to 800 watts of power. It is especially a good match for 25-size 3D airplanes such
as the E-flite Eratix 25e. It is also a great high power motor for the E-flite DHC-2 Beaver 25e, Deuces Wild 25e2, Pulse 25e, and Hangar 9 Sundowner 36.

* Maximum Operating Temperature: 220 degrees Fahrenheit
* Adequate cooling is required for all motor operation at maximum current levels.
* Maximum Burst Current duration is 30 seconds. Adequate time between maximum burst intervals is required for proper cooling and to avoid overheating the
motor.
* Maximum Burst Current rating is for 3D and limited motor run flights. Lack of proper throttle management may result in damage to the motor since
excessive use of burst current may overheat the motor.
Note: The 3.5mm Gold Bullet Connectors included on this motor are rated for current up to 60A. Please see our accessory parts listed below for 4mm
connector option if you are running more current than we recommend.
Determine a Model’s Power Requirements:
1. Power can be measured in watts. For example: 1 horsepower = 746 watts
2. You determine watts by multiplying ‘volts’ times ‘amps’. Example: 10 volts x 10 amps = 100 watts
Volts x Amps = Watts
3. You can determine the power requirements of a model based on the ‘Input Watts Per Pound’ guidelines found below, using the flying weight of the model
(with battery):
• 50-70 watts per pound; Minimum level of power for decent performance, good for lightly loaded slow flyer and park flyer models
• 70-90 watts per pound; Trainer and slow flying scale models
•
90-110 watts per pound; Sport aerobatic and fast flying scale models
•
110-130 watts per pound; Advanced aerobatic and high-speed models
• 130-150 watts per pound; Lightly loaded 3D models and ducted fans
• 150-200+ watts per pound; Unlimited performance 3D models
NOTE: These guidelines were developed based upon the typical parameters of our E-flite motors. These guidelines may vary depending on other motors and
factors such as efficiency and prop size.
4. Determine the Input Watts per Pound required to achieve the desired level of performance:
Model: 25-size aerobatic/3D airplane
Estimated Flying Weight w/Battery: 4.1 lbs
Desired Level of Performance: 130-150 watts per pound; Lightly loaded 3D models
4.1 lbs x 130 watts per pound = 533 Input Watts of total power (minimum)
required to achieve the desired performance
5. Determine a suitable motor based on the model’s power requirements. The tips below can help you determine the power capabilities of a particular motor
and if it can provide the power your model requires for the desired level of performance:
• Most manufacturers will rate their motors for a range of cell counts, continuous current and maximum burst current.
•
In most cases, the input power a motor is capable of handling can be determined by:
