Complete FPV Drone Kits or Tethered ISR Drone Starter Kits (motors + ESC + FC + ELRS + camera/gimbal + fiber tether option)

Description

Tactical Long-Range Intelligence & Stand-Off Reconnaissance System

This kit is configured for long-endurance, high-altitude scouting missions where high-fidelity target acquisition must be paired with redundant avionic sensors. It provides a heavy-lift 10-inch or large-scale fixed-wing framework capable of operating miles from the ground station with exceptional positional hold.

Avionics Safeguard: The Matek 12S Pro BEC isolates the flight controller and telemetry links from the extreme voltage ripples generated by the main multirotor electronic speed controllers (ESCs), ensuring that high-load throttle punches never cause brownouts or sensor clipping.

Kit 2: The ‘FOG-D / Invisible Tether’ Flight Pack

Radio-Silent, Unjammable Fiber-Optic Guided Drone (FOG-D) Kit

Engineered specifically for electronic warfare environments where radio frequency (RF) bands are saturated or intentionally jammed. This kit relies on a physically deployed glass thread to transmit telemetry and uncompressed video back to the pilot, maintaining a 100% radio-silent signature that cannot be detected by RF sniffers or countered by localized jammers.

Core Architecture & Structural Framework

• Aviation-Grade Carbon Fiber Frame: High-rigidity 10-inch or large tactical multi-rotor frame with beefed-up 8mm carbon arms. Its spacious layout is optimized to host an underslung canister without introducing center-of-gravity imbalance.

• Airborne Micro-Spool Canister: An ultra-lightweight ABS canister packing 3KM to 10KM of G.657.A2 bend-insensitive single-mode optical fiber ($200\mu\text{m}$ thread profile). The spool dispenses effortlessly from the airframe under zero tension, laying completely stationary on the terrain below to eliminate snagging.

• Optical-to-Digital Media Converters: Onboard mini transceiver modules that instantly translate standard serial UART (MAVLink) and IP Ethernet video signals into high-speed laser pulses, routing them across a single strand of glass.

Propulsion, Payload, and Backup Electronics

1. High-Torque Powertrain Integration: Driven by heavy-duty outrunners (such as the T-Motor AT7215 series) paired with ultra-rigid matched carbon fiber propellers, providing massive torque handling and vertical lift stability to cleanly carry the fiber payload.

2. Ultra-Lightweight Multi-Spectral Payloads: Outfitted with the featherweight Viewpro Q818X Micro Dual-EO Gimbal (215g). By substituting heavy mechanical zoom barrels for a dual fixed-lens setup, it provides a stable 40x hybrid zoom and 640×512 thermal imaging without introducing a parasitic weight penalty.

3. ExpressLRS Emergency Command Link: Features an onboard ELRS receiver acting as a fail-safe hardware backup. In the rare event of a physical fiber break, the autopilot instantly opens the encrypted ELRS RF channel, enabling immediate manual override routing or triggering an automated Return-to-Home (RTH) protocol.

Kit 3: The ‘Persistent Surveillance’ Ground-Fed Kit

Infinite-Endurance Tethered Station (Continuous Power & Data Umbilical)

Designed for fixed, long-duration installations such as border checkpoints, event security, emergency communication relays, and industrial asset monitoring. This kit trades mobility for unlimited time-on-station, drawing continuous power directly from a ground station.

• Motorized Active-Tension Payout Reel: A heavy-duty ground winch system driven by synchronous smart motors. Integrated altitude-tracking sensors continuously adjust tension, actively spooling the cable in or out to keep the line perfectly taut and clear of the drone’s propellers.

• Integrated Optical Slip-Ring (FORJ): The ground drum features a precision dust-proof Fiber Optic Rotary Joint, allowing the main reel to spin continuously without tangling or degrading the internal laser data pipeline.

• Ruggedized Hybrid Power-Data Cable: A specialized, Kevlar-reinforced umbilical combining high-voltage copper conductors ($250\text{V}$ to $600\text{V}$ AC/DC capacity to eliminate voltage drops over long distances) alongside a dual-strand single-mode bend-insensitive fiber core, all wrapped in a low-friction, IP67-rated polyurethane jacket.

• High-Voltage Airborne Down-Converter: Mounted to the drone chassis, this compact module steps down the incoming high-voltage ground feed to standard 12V/24V DC lines, supplying raw power to the motors and clean, isolated currents to high-end payloads like the SIYI ZT30 Four-Sensor 30x Zoom Gimbal.
