EPF Hobbies Mercury 90mm 1900KV-CCW 6-7S Li-Po
This Mercury 90A Metal EDF unit is a cutting edge of EDF design. All Mercury 90A Metal EDF parts are manufactured with precision CNC machine tools to maintain strict tolerances while enables a high level of accuracy in the manufacturing process.
This EDF is milled from aircraft grade high tensile Aluminum alloy to improve performance and also to help reduce deformity of the duct during installation. Moreover, the aluminum alloy structure acts as a heat sink for improved heat dissipation. There are 8 fan blades together with the motor are also milled from high tensile aluminum alloy as a single assembly. In addition, the fan-motor assembly has a cooling fan incorporated into it, as well as dynamically balanced at the factory, which means a time saver and less frustration for modeler from not having to spend hours balancing the fan unit and the motor.
This EDF unit has been tested in the wind-tunnel using Computer Aided Evaluation and found to reduce high speed deformation by 90%, as compared to a conventional ABS or plastic fan. The Mercury 90A Metal EDF incorporates an innovative 3-bearing system to reduce resonance vibration by 90%. This vibration is common to all EDF design, which is caused by both the fan and motor vibration, which causes the blade tips to rub against the shroud of the duct.
Fan Jets USA only recommends that this edf unit is run on a 6-7S. Running this edf unit on a 8s is not recommended and is only for reference below.
