Powerfun EDF 64mm Ducted Fan 4S 3500KV Brushless Motor 11 Blades Propeller for RC Airplane Plane Jet
A part of the review has been auto-translated.
The fan was sent the next day and in 11 days I received it in Spain. Pretty fast. In a simple bag but well protected with airbags. Perfect condition. Working properly. Good impression. Tests with 4S Nanotech 45C battery, 2,650 mah with 6~ 7 usage charges and newly output charger (4.2 volt per element) and Esc Skywalker 80 amp. I got 47.5 Amp. The next day, after the tests did not pass 45 amp.All this out of pipes and the plane. These are optimal conditions that I consider difficult to overcome. Then tested the 35C nanotech 2.650 4S battery, the result was equal, 45 amp.When charging this amperage both batteries lower a little voltage (2 volt), so powering with a much better battery or a feeder able to keep the 16.8 volts constant could reach the amps. (52). Then the voltage is lowered in normal mode. Battery tested at storage level (3.8 volts/element) offers even amps. The important thing is traction and I'll do tests later. Connectors 3.5. Cone tip spot is sealant.
Everything as described and super quality
