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.
good quality product, shipment within normal and without problems, arrived well. thank you
