overheat the motor.
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
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):
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: 27% Extra 260 ARF
Estimated Flying Weight w/Battery: 15.3 lbs
Desired Level of Performance: 150-200+ watts per pound; Unlimited performance 3D and aerobatics
15.3 lbs x 150 watts per pound = 2,295 Input Watts of total power (minimum)
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:
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: 27% Extra 260 ARF (converted to electric)
Estimated Flying Weight w/Battery: 15.3 lbs
Total Input Watts Required for Desired Performance: 2,295 (minimum)
Motor: Power 160
Max Continuous Current: 60A*
Max Burst Current: 78A*
Cells (Li-Po): 10
10 Cells, Max Burst Power Capability: 33 Volts (10 x 3.3) x 78 Amps = 2,574 Watts
Per this example, the Power 160 motor (when using a 10S Li-Po pack) can handle up to 2,574 watts of input power, readily capabl
27% Extra 260 model with the desired level of performance (requiring 2,295 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.
Volts x Amps = Watts
• 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 and aerobatic models
required to achieve the desired 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
10 Cells, Continuous Power Capability: 33 Volts (10 x 3.3) x 60 Amps = 1,980 Watts

Electronic Speed Controls:
There are many brushless electronic speed controls available in the market. We have conducted our testing using Jeti Advance 90 Plus and the Castle Phoenix HV-85 and HV-110 ESCs. The
timing setting of the speed control is important for obtaining proper and maximum performance. In the past, some consumers have reported motor performance issues relating to timing at
higher power levels when using the Castle Phoenix HV-85 and HV-110 speed controls. Castle Creations has updated their software to correct these issues. To ensure you have the most upto-date software, we recommend that you update your ESC by downloading the software from their web site using the Castle Link USB Programmer Adapter (CSEPHXL).
Propellers:
Our testing was conducted using APC electric propellers. At these power levels, you may also experiment with using regular gas/glow props in the equivalent sizes listed in our specifications.
Other options are available as well and will affect motor power output and RPMs.
Installation of Prop Adapters:
This motor includes two 12mm prop adapters tapped to accept 10-32 spinner mounting screws in order to allow quick and easy mounting of most spinners. There are two different prop shaft
adapters. The adapter with four holes is intended for installation on the rotating portion of the case. Use this adapter when you are installing the fixed portion of the motor on the outside of a
firewall or mount.
1. Use the included 4-40 x 3/8” screws to attach the prop adapter to the rotating portion of the case.
2. It is important that you then slide the included securing collar onto the motor shaft exiting the fixed portion of the motor. Slide the collar up to the retaining ring and tighten the
The adapter with two setscrews is intended for installation on the motor shaft exiting the fixed portion of the case. Use this side when you are installing the fixed portion of your motor on the
inside of a firewall or mount.
1. Slide the prop adapter onto the motor shaft exiting the fixed portion of the case.
2. Use two setscrews to secure the prop adapter to the motor shaft, making sure that one of the setscrews lines up with the flat spot of the motor shaft.
Note: Use blue thread lock to secure screws.
Operating Instructions:
1. This brushless motor requires the use of a sensorless brushless speed control. Failure to use the correct speed control may result in damage to the motor and/or speed control.
2. When mounting the motor, be sure the correct length of screws are used so damage to the inside of the motor will not occur. We suggest you use the mounting hardware included
3. You may connect the three motor wires directly to the controller with solder or use connectors such as 4mm gold plated brushless connectors (EFLA249), which will also need to
