RC ERA C170 ESC Speed Controller Board for 1:48 Scale Apache Helicopter

Eliminate Motor Cogging, Prevent Thermal Shutdowns, and Restore Instantaneous Throttle Response During Inverted 3D Stunts

The electronic speed controller (ESC) is the powerhouse of your flybarless drivetrain, responsible for regulating high-current battery power into smooth, continuous RPM changes for the brushless motors. For an advanced scale model like the RC ERA C170 Longbow Apache, performing hard pitch pumps or tight collective maneuvers in 3D stunt mode places a heavy thermal load on the internal power circuits. Continuous aggressive flying, motor binding from grass tangles, or poor airflow can overheat the miniature MOSFET switches, leading to motor stuttering, sudden mid-air shutdowns, or total loss of tail rotor synchronization. Replacing your burnt out or glitching power drive with this factory-original C170 ESC module ensures stable voltage conversion, cooler operating temperatures, and lightning-fast throttle response under heavy flight loads.  Ships worldwide.

Product Highlights

• High-Efficiency Surface Mount MOSFET Array: Engineered to handle high peak currents without sagging, providing linear power delivery to maintain constant head speed.

• External Ripple-Filtering Capacitor: Features a pre-soldered green cylindrical filter capacitor to stabilize voltage intake and protect the sensitive mainboard electronics from voltage spikes.

• Factory-Soldered Multi-Color Data Leads: Includes flexible, pre-tinned signal input lines (red, yellow, black) for low-resistance data transfer directly from the flight receiver.

• Ultra-Compact Dual-Drive Architecture: Manufactured on an ultra-lightweight, spacesaving PCB layout that integrates perfectly within the tight constraints of the Apache internal scale frame.

Compatibility

For the RC ERA C170 1:48 Scale Longbow Apache RC Helicopter only.

What’s in the Box

• 1 x RC ERA C170 ESC

Install Tips

• Removing the Damaged ESC Module: Unfasten the main fuselage shells; carefully desolder the main motor power output leads from the old board, unplug the signal connector from the flight controller, and remove the damaged board from its mounting tray.

• Seating and Isolating the New ESC Circuitry: Slide the fresh ESC module into its designated frame bracket, ensuring the green filtering capacitor sits flat and is completely isolated from rubbing against any rotating drive gears or links.

• Soldering and Routing Power Connections: Solder your main brushless motor power supply leads securely to the output pads on the board edge; route the multi-color input signal harness cleanly along the frame chassis without crimping the insulation lines.

• Initializing and Pre-Flight Throttle Checks: Plug the control connector back into the flight controller channel; securely close your fuselage, power on your transmitter, connect a fresh battery pack on a level surface, and complete a low-RPM ground test to check for correct motor spin directions before clearing your model for takeoff.
