Schubeler DS-98-DIA HST 128mm Axial EDF Jet Propulsion System

The Schubeler DS-98-DIA HST is a high-performance 128mm axial electric ducted fan (EDF) system engineered for large-scale RC jet aircraft. Featuring a precision 12-blade axial compressor and an advanced Schubeler electronically commutated (EC) brushless motor, this system delivers exceptional thrust, efficiency, and scale-realistic jet sound.

Designed for jet models up to 11 kg (24 lb), the 128mm compressor produces a superior compression ratio with a maximum rotational speed of 26,500 RPM, exhaust velocity of 95 m/s, and up to 10 kg (22 lb) of thrust. The compact 105mm exhaust diameter allows efficient installation in large EDF jets while maintaining outstanding airflow performance.

The aerodynamically optimized 12-blade axial fan is modeled after full-scale turbofan speed ratios, delivering high internal efficiency, smooth throttle response, realistic jet acoustics, and whisper-quiet idle operation.

Advanced DSM6043 Integrated Brushless Motor

At the heart of the DS-98-DIA HST is the Schubeler DSM6043 high-torque brushless motor, engineered specifically for axial EDF applications. Producing 2.2 Nm of torque at 26,000 RPM, this four-pole, 12-slot motor features:

• Large 67mm motor diameter with 40mm magnet length

• Integrated airflow design for direct cooling (no internal fan required)

• Carbon-reinforced rotor with IMS carbon fiber banding for high-RPM durability

• High-temperature winding and adhesive system for extreme operating conditions

• Precision dual-bearing shaft system for low noise and long service life

All rotating components are dynamically fine-balanced for smooth, vibration-free operation.

Carbon Fiber Construction & Precision Engineering

The propulsion system features:

• 12 hand-crafted carbon fiber rotor blades mounted in precision aluminum blade holders

• 4 carbon fiber stator vanes integrated into a UHM carbon sandwich shroud

• Hard-anodized aluminum housings and reinforced magnet carriers

• Patented cooling design for consistently cool motor operation

This construction ensures maximum strength, crash resistance, and long-term reliability.
