Description

This Mercury 74mm Metal EDF unit is a cutting edge of EDF design. All Mercury 74mm 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 10 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 74A 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.

Flight Tip Caution: Motor will overheat and may burnt out at high timing. Make sure to set the ESC timing to LOW or 2 degree setting.

WARNING: Operating the motor outside of the specifications listed above can either damage the motor, battery or esc. It is important that these components are set up properly. Failure to do so can void the warranty. It is strongly encouraged to use a Watt Meter to test the watt and amp performance when setting up a new system. If the output is above the factory recommended specs, then it needs to be adjusted by the esc. The timing and throttle settings on the esc can help to set the appropriate levels.
