RC ERA C170 Optical Flow Sensor Laser Module for 1:48 Scale Apache Helicopter

Fix Automatic Hover Drift, Eliminate Unstable Altitude Drops, and Restore Precise Indoor/Outdoor Laser Positioning Control

The optical flow camera and laser module sensor group is the core component responsible for maintaining the helicopter's rock-solid position hold and precise altitude metering. For a premium 1:48 scale flybarless model like the RC ERA C170 Longbow Apache, this under-belly sensor module continuously reads ground textures and calculates laser bounce-back latency to stop drifting. Hard landings, exposure to ground dust, or impact vibrations can scratch the micro lenses, damage the optical matrix, or loose cable continuity. When this sensor module fails, the helicopter will experience sudden altitude dropouts, drift blindly in low winds, or fail to activate its beginner-friendly auto-hover modes. Replacing your faulty positioning module with this factory-original unit instantly restores hands-free hover stability and flawless terrain-following performance.  Ships worldwide.

Product Highlights

• Integrated Dual-Engine Positioning System: Combines a high-frequency optical flow ground-tracking camera lens with a dual-lens laser rangefinder sensor to maintain precise location lock.

• Pre-Balanced Onboard Electronic Core: Factory calibrated to match the stock C170 flybarless master program, preventing sensor reading mismatches or sudden drift errors.

• Pre-Assembled 4-Wire Connection Harness: Includes a flexible, insulated color-coded wire loom with a matching terminal head to plug directly into the receiver matrix without soldering.

• Ultra-Lightweight Micro Chassis Footprint: Engineered to snap securely inside the lower belly cavity of the scale Apache fuselage hull without changing the center of gravity.

Compatibility

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

What’s in the Box

• 1 x RC ERA C170 Optical Flow Sensor

Install Tips

• Removing the Damaged Sensor Module: Disassemble the lower belly shell of your Apache; disconnect the 4-pin electronic terminal from the flight controller board and lift the old module out of its plastic seat.

• Seating the New Positioning Board: Position the fresh module circuit board into the lower chassis slot, ensuring the camera lens and twin laser pods point straight down through the openings in the fuselage skin.

• Connecting the Terminal Data Bus Line: Route the color-coded 4-wire connector loop cleanly through the frame tracks; plug the terminal head straight into the designated matching socket on your master flight controller board, checking that all pins click together tightly.

• Pre-Flight Lens Cleaning and Initialization: Wipe the micro camera and laser lens surfaces gently with a soft microfiber cloth; power on your RC ERA C170 on a clean, flat surface to let the optical sensor calibrate properly before initiating an auto-takeoff.
