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 12 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.

1. The first EDF with Motor Shaft Cooling / Turbo Inner-cooling System in the world.
2. The Turbo Inner-cooling System allows motor to cool down to room temperature within 15~20 seconds at half throttle.
3. 60,000 RPM High Speed Dynamic Motor and Fan balance adjustment.
4. High Precision CNC Cutting for the Rotor and Fan.
5. The 12 fan blade is the first in the world to use high tensile aluminum alloy.
6. Fully supported motor shaft with 3 end to end bearings.
7. Replaceable motor core without disrupting the precision balanced motor can and fan assembly.
8. All Alloy Design
9. Optimized Air Flow.

Flight Tip: Set the ESC timing to LOW or 2 degree setting. As with any type of electric motor, apply the 80% rule for best experience.
