EPF Hobby Mercury II 8 Blades 64mm EDF Ducted Fan + 4700Kv Motor 4s (CW)

EPF Hobby Mercury II 8 Blades 64mm EDF Ducted Fan + 4700Kv Motor 4s (CW)

EPF Hobby Mercury II 8 Blades 64mm EDF Ducted Fan + 4700Kv Motor 4s combo, pre-mounted and dynamically balanced.

Mercury EDF are full alloy high precision CNC made and are offering a very good thermal dissipation. The 8 blades rotor is also made of aluminium and accepts high rotation speeds. The front "spinner" does not rotate (vibration risk elimination) and is protected between 2 sets of 4 stators. Eliminating any risk of rotor ejection. The brushless motor is located at the front of the edf for a better head dissipation.

Description

• Turbo Innercooling System let EDF down to room temperature whithin 15~20 seconds hald throttle.
• 60000 RPM High Speed Dynamical Balance Adjustment Rotator and Fan 
• High Precision CNC Cutting Rotator and Fan
• The 8 fan blade is the first in the world to use high tensile aluminum alloy.
• Full Alloy Design
• Optimized Air Flow.

The controller should be chosen 20% over rated due to the long lasting load.
LV = low voltage controller up to 6s, HV = high voltage controller above 6s.
Battery should be chosen about 15/ - 1/20 of the max current for 4-3 minutes WOT. 30-40 C is appropriate.

* Caution: best working performance for the 4700kv is achieved with a 3s Lipo. When using it with 4s, please make sure your transmitter thrust curve limits the max motor current to 70A. Otherwise some controllers or controllers setups may produce a current over 85A and will damage the motor. This unit works with 4s.

Note: higher capacity and quality Lipo can produce better performances. Please read the below manufacturer table :
