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: E-flite Mini Edge 3D ARF
Estimated Flying Weight w/Battery: 1.6 lbs
Desired Level of Performance: 150-200+ watts per pound; Unlimited performance 3D models
1.6 lbs x 150 watts per pound = 240 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:
Average Voltage (depending on cell count) x Continuous Current = Continuous Input Watts
Average Voltage (depending on cell count) x Max Burst Current = Burst Input Watts
HINT: The typical average voltage under load of a Ni-Cd/Ni-MH cell is 1.0 volt. The typical average voltage under load of a Li-Po cell is 3.3 volts. This means the typical average voltage under load of a 10 cell Ni-MH pack is approximately 10 volts and a 3 cell Li-Po pack is approximately 9.9 volts. Due to variations in the performance of a given battery, the average voltage under load may be higher or lower. These however are good starting points for initial calculations.
Model: E-flite Mini Edge 3D
Estimated Flying Weight w/Battery: 1.6 lbs
Input Watts Per Pound Required for Desired Performance: 150 (minimum)
Motor: Park 480 Brushless Outrunner, 1020Kv
Max Continuous Current: 22A*
Max Burst Current: 28A*
Max Cells (Li-Po): 3
3 Cells, Continuous Power Capability: 9.9 Volts (3 x 3.3) x 22 Amps = 218 Watts
3 Cells, Max Burst Power Capability: 9.9 Volts (3 x 3.3) x 28 Amps = 277 Watts
Per this example, the Park 480 Brushless Outrunner, 1020 Kv motor (when using a 3S Li-Po pack) can handle up to 277 watts of input power, readily capable of powering the Mini Edge 3D with the desired level of performance (requiring 150 watts minimum). You must however be sure that the battery chosen for power can adequately supply the current requirements of the system for the required performance.
Battery Choices:
There are many Li-Po battery brands on the market with several choices for consumers. We recommend either E-flite or Thunder Power batteries and list some possible choices for the Park 480 Brushless Outrunner motor, all depending on the airplane application. NOTE: Battery technology is constantly changing and improvement are made often. Some part numbers below may change as improved versions are introduced.

Note: If using larger propeller sizes with 3S Li-Po, due to high power output and current demands of this motor, we recommend the use of packs capable of delivering a minimum of 30A continuous current. Good examples of these packs would be the Thunder Power PRO LITE 2100 mAh 3S packs (THP21003SPL). We do not recommend the use of packs that cannot deliver at least 30A continuous current like the Thunder Power Generation II 2100 mAh 3S packs (THP21003S) unless using smaller diameter and lower pitch propellers.

Expect extreme awesome power and performance with good speed and strong vertical performance and pull out from hover. Using a 12x6 prop will provide better thrust with slightly less speed than if you used an 11x7 propeller. This motor is more suitable for higher output batteries such as the Thunder Power PRO LITE packs. Average duration is approximately 8-12 minutes depending on throttle management.
Option 2:
Motor: Park 480 Brushless Outrunner, 1020Kv
