EDF 73mm EMV - COMPLETE MODULAR SYSTEM - (5-7-9-11 Blades | Multi-Motor Fit)
EMV Edf 73 mm complete for all rc models.
🛠️ Professional EDF System: High-Thrust Modular Design Designed by an RC Pilot for true RC enthusiasts. This isn't just a 3D model—it's a flight-tested propulsion system engineered for maximum efficiency, clean aerodynamics, and ease of assembly.
🌟 PROPRIETARY FEATURES: "Shell-Lock" Stator (Exclusive Design): My innovative split-stator housing snaps perfectly around the motor.
Zero-Drag Cable Management: One of the stator vanes acts as a structural conduit for Outrunners Motors!! Your motor wires are "hidden" inside the airfoil, protecting them from the spinning rotor and eliminating aerodynamic turbulence for a cleaner intake.
Precision-Engineered Rotors: Unique blade pitch, curvature, and twist designed for high static thrust and that authentic, high-pitched "jet" sound.
Specific for all 4mm shafts motors.
⚠️ WARNING: FOR EXPERT BUILDERS ONLY – READ BEFORE PRINTING To operate these fans safely at high RPM, two mandatory mechanical procedures are required:
Shaft Modification (Mechanical Lock): You MUST cross-drill the motor shaft (1.2mm) to install a steel locking pin. This is the only way to safely anchor the rotor against high torque.
Mandatory Dynamic Balancing: 3D-printed rotors are DIY components and MUST be dynamically balanced before use. High-RPM rotation without proper balancing WILL lead to catastrophic structural failure (explosion). Use at your own risk.
Material Recommendation: Rotors should be printed in high-tenacity materials like Carbon Fiber Nylon (PA-CF) for structural integrity.
📦 WHAT’S IN THE BOX: Main Fan Shroud (Optimized versions for both Inrunner & Outrunner motors).
Complete set of Rotors (5, 7, 9, and 11-blade options).
Tested with 28 size motor 3850 kv in 3s with 5 blades HDT rotor produce 1,0 kg of thrust and 47 amps.
You can brush rotors with ca glue to increase strenght.
SAFETY INFORMATIONS:
WARNING!!
This object may cause seriously eyes injury without experience and balancing knowdlege! It's strickly avoid for beginners. Rotors run at high rpm and only experienced modellist must use it.
3D printing settings 0.4 nozzle. 6 perimeters for rotors. 40% infill gyroid. Zigzag supports for Arms and internal bodies. (7% density). No cooling. Raccomended brim. not over 38 mm/sec speed. -___________________________________________________________________-
Note: Photos shown are for the 73mm version (except for the 150mm render). All fans share the same proven engineering and "Shell-Lock" design.
