Mark4 V3 Pro 15-Inch Heavy Lift FPV Frame Kit – 680mm Carbon Fiber Long Range X-Class

Go Big. Fly Far.
The Mark4 V3 Pro 15-Inch is a beast of a frame designed for extreme long-range exploration and heavy-lift cinema applications. With a massive 680mm wheelbase and reinforced construction, this platform is engineered to carry larger payloads, big batteries, and professional camera gear with absolute stability.

Unmatched Rigidity with 8mm Arms
Flex is the enemy of large drones. The Mark4 V3 Pro solves this with substantial 8mm thick carbon fiber arms. Combined with a 3mm bottom plate and surrounding reinforcement braces, this frame eliminates resonance and vibration, ensuring your footage remains smooth even when spinning massive 15-inch propellers.

Big Motor Support
Designed for power, the motor mounts feature a 21x21mm bolt pattern with M4 screw holes, specifically tailored for large-stator motors (such as 4312, 4320, or similar X-Class motors).

Key Features:

• X-Class Geometry: Wide 680mm stance for maximum stability in high winds.

• Heavy Duty Carbon: 8mm arms and 3mm fuselage plates provide a rigid, crash-resistant structure.

• Dual Stack Mounting: Compatible with both 20x20mm and 30.5×30.5mm electronics, giving you flexibility in choosing Flight Controllers and VTX units.
