High-performance 9" FPV frame with 6mm thick arms and a 387mm wheelbase. Optimized for ultra-long-range missions and heavy cinematic payloads.
Dominate long-distance flight with unrivaled structural authority. The MAK4 V2 9-Inch Frame is the ultimate platform for exploratory FPV and industrial payload delivery. With an expansive 387mm diagonal wheelbase, this frame provides the clean air and disk clearance necessary to run 9-inch propellers with high efficiency and minimal vibration.
Probots ProSpec Grade Durability This frame is Probots ProSpec Grade, utilizing reinforced 6mm thick arms to provide a rock-solid foundation for high-torque 3110 series motors. The V2 structural layout includes a 3mm bottom plate and 2mm top plate, creating a rigid "box" for the flight electronics. The side plates are 2.5mm thick to protect the FPV camera from impacts during technical landings or low-altitude flight. Its elongated body design offers a spacious internal deck, allowing for the installation of large flight stacks, multiple GPS modules, and high-power video transmitters.
Diagonal Wheelbase: 387mm
Front-to-Back Dimension: 249mm
Side-to-Side Dimension: 296mm
Arm Plate Thickness: 6.0mm
Bottom Plate Thickness: 3.0mm
Top Plate Thickness: 2.0mm
Side Plate Thickness: 2.5mm
Material: 3K Twill Carbon Fiber
Ultra-Long Range: Capable of carrying massive 6S2P Li-Ion packs for missions exceeding 30 minutes.
Heavy-Lift FPV: Rigid enough to carry high-end cinematic cameras on a top-mounted gimbal.
Search and Rescue: Stable platform for mounting specialized FLIR or high-zoom optics.
Unlock New Capabilities (Project Evolution)
Feature Upgrade: The independent 6mm arm design allows for individual arm replacement, ensuring that a single incident doesn't ground your entire mission-ready platform.
Effort Level: Intermediate. Assembly of the thick-cut carbon plates and provided aluminum hardware is required.
Package Includes:
4 x 6mm Carbon Fiber Independent Arms
1 x 2mm Carbon Fiber Top Plate
1 x 3mm Carbon Fiber Bottom Plate
1 x Hardware Pack (Aluminum Standoffs & M3 Screws)
