Standards & references

• India Drone Rules, 2021 (G.S.R. 589(E)) — Rule 5 classifies drones by maximum all-up weight including payload; at the stated 26.5 kg maximum takeoff weight the MX15-6 falls in the medium class (over 25 kg up to 150 kg), and Rule 14 requires Digital Sky registration before operation.
• DoT Wireless Planning & Coordination (WPC) spectrum management, India — The 915 MHz receiver and 2.5 W 5.8 GHz video transmitter must be used only on permitted frequencies and power levels.
• ExpressLRS project documentation — Reference for the ELRS915M control-link protocol used by the receiver.

Intelligence Brief

Mission overview

FlySpark 15-Inch MX15-6 Heavy-Lift FPV Drone is a compact high-payload FPV UAV platform designed for professional payload testing, industrial FPV work, field training, inspection support, UAV R&D, utility payload trials and custom drone integration. Built on a 15-inch MX15-6 frame with 790mm wheelbase, the platform combines a smaller airframe size with a strong payload rating, making it suitable for users who need heavy-lift capability without moving to a very large 24-inch class drone.

The drone uses an F722 flight controller, 80A 8S ESC system, 5322-440KV motors, 1507 propellers, ELRS915M receiver, 5.8GHz 2.5W video transmitter, 5.8GHz long-range antenna and 1500TVL FPV camera. The drone body weight is approximately 4300g. It is rated for a 15kg payload, supports up to 18kg maximum load, and has a maximum takeoff weight of 26.5kg.

The recommended battery configuration is 8S 16000mAh × 2. With rated load and the recommended dual battery setup, the listed flight time is approximately 15 minutes. The maximum flight speed is listed at 120km/h, making this a powerful high-speed FPV platform for trained operators working in approved and controlled environments.

FlySpark MX15-6 is best suited for professional FPV teams, UAV integrators, payload developers, inspection teams, R&D labs, training centers and advanced operators who need a compact heavy-lift FPV platform with strong propulsion, high-power analog video, long-range receiver support and practical payload capacity.
