🛠️ Professional EDF System: High-Thrust Modular Design Seventh Type EMV EDFs.

🚀 THE HEAVYWEIGHT TRIO: 120mm - 123mm - 128mm Professional EDF Seventh, Eighth, and Ninth types of my professional EDF fleet. These sizes are the "Sweet Spot" for large-scale RC Jets and high-performance projects. At this scale, the airflow volume is massive, and the structural integrity of my Shell-Lock design really shines.

🛠️ ENGINEERING FOR BIG BIRDS: Designed by an RC Pilot for those who need serious static thrust. These fans are engineered to handle the brutal torque of large brushless motors while maintaining a clean, aerodynamic profile.

🌟 PROPRIETARY FEATURES:

"Shell-Lock" Stator (Heavy Duty): My innovative split-stator housing is reinforced for these diameters to ensure the motor stays perfectly centered under extreme load.

Pro-Level Cable Stealth: One of the stator vanes is a structural conduit for outrunner wires. Zero turbulence, 100% protection.

Precision Monster Rotors: Curvature and twist optimized for large-scale displacement and that "Real Turbine" roar. 🔊

⚠️ STRICKLY FOR EXPERT BUILDERS - HIGH ENERGY SYSTEM Operating a big fan requires respect for physics:

Mechanical Lock (Mandatory): You MUST cross-drill the motor shaft for a steel locking pin. 🔩

Professional Balancing: At these diameters, an unbalanced rotor is a grenade. MUST be balanced. ⚖️

Materials: Use ONLY high-quality Carbon Fiber Nylon (PA-CF) or similar high-tenacity filaments.

Note: Drawed photo are similar for all edfs! So, except for 73 mm, here you can find the sames for all (from 83 to 138. Only 150 mm has originals rendering photos). I had made photos only for edf 73 printed, right now.

📦 TECHNICAL PACKAGE:

Main Fan Shroud: Optimized for large Inrunners and Outrunners. Full Rotor Suite: 5, 7, 9, and 11-blade options included.

Shaft Compatibility: Hubs designed for heavy-duty motor shafts.

Pro Tip: Brush rotors with Cyanoacrylate (CA) glue after printing and before balancing for extra surface rigidity. 🛡️

_____________________________________________________- 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 (OPTIMIZED FOR SIZE):

Nozzle: 0.4 mm. Perimeters: 8 perimeters for Rotors and Bodies (Strength is life!). Infill: 45% - 50% Gyroid. Speed: Max 35-40 mm/sec (Slow and steady for perfect layer adhesion). Cooling: NO cooling for maximum structural bond.
