E-flite Power 46 Brushless Outrunner Motor, 670Kv - Manual

Power 46 Brushless Outrunner Instructions
Thank you for purchasing the E-flite Power 46 Brushless Outrunner motor. The Power 46 is designed to deliver clean and quiet power
for .40 to 46-size sport and scale airplanes, 25- to 40-size 3D airplanes, or models requiring up to 800 watts of power. It’s an especially
good match for Hangar 9® .40-size trainers like the Alpha .40 (HAN2450), Arrow .40 (HAN2625) and warbirds like the T-34 Mentor 40
(HAN2425). Also a great match for sport planes like the Ultra Stick 40 (HAN1675 or HAN1690), Seagull Spacewalker 40 (SEA2050),
and smaller sport 3D planes like the Twist 40 (HAN2650).
Power 46 Brushless Outrunner Features:
• Equivalent to a 40- to 46-size glow engine for 4- to 7-pound (1.8 - 3.2-Kg) airplanes
• Ideal for 25- to 40-size 3D airplanes up to 5-pounds (2.2 Kg)
• Ideal for models requiring up to 800 watts of power
• High torque, direct drive alternative to inrunner brushless motors
• Includes mount, prop adapters, and mounting hardware
• Quiet, lightweight operation
• External rotor design, 6mm shaft can easily be reversed for alternative motor installations
• High quality construction with ball bearings and hardened steel shaft
• Slotted 12-pole outrunner design

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.
