The MARK4 V2 8-Inch is made from high-grade carbon fiber for lightweight strength and impact resistance. The page describes a 367 mm wheelbase with a compact design and multiple mounting options.
It supports 19x19 mm cameras and 20x20 mm and 30.5x30.5 mm flight controllers, is reinforced with stiffening plates and arm bracers, has an X-type structure, 6 mm thick arms and a frame size of 234 x 282 mm. It is built from premium 3K carbon fiber for FPV racing, freestyle and long-range flights. The page showed only 4 left at Rs 3,362 (SKU TIFQC0146).
367 mm wheelbase: with a compact design.
3K carbon fiber: lightweight strength and impact resistance.
6 mm thick arms: as listed.
Stiffening plates and arm bracers: for durability.
19x19 camera and 20x20 / 30.5x30.5 FC mounting: as listed.
X-type structure: 234 x 282 mm frame size.
A drone frame is the skeleton that holds everything together: the arms carry the motors, the plates carry the flight controller, ESCs, battery and camera, and the whole structure must be stiff enough that vibration does not reach the gyro. Carbon fibre is the standard material because it is light and very rigid. The wheelbase, measured motor to motor across the diagonal, sets the size of propeller the frame can carry, and the arm thickness sets how well it survives crashes.
Match the frame to your parts. Check the motor mounting pattern, the flight controller and ESC stack hole spacing, the camera width, the video system you want to fly and the largest propeller the arms allow. TPU parts such as arm guards, antenna mounts and camera mounts are printed in a flexible plastic so they absorb impact. The battery strap and anti-slip pad keep the pack from moving under G-force.
Build carefully. Use thread-locking compound on the metal screws that are not in a plastic nut, keep the screw lengths from the hardware bag matched to the holes they belong in, and do not over-tighten screws into carbon fibre. Route motor wires away from sharp plate edges, mount the flight controller on soft grommets when the frame supports it, and check that nothing rubs a propeller before the first flight. After a crash, inspect the arms for cracks and replace any that are damaged.
Plan the balance of the build. A heavier battery moves the centre of gravity, so place it where the frame is designed to carry it, and keep the antenna, GPS and camera clear of the carbon plates where possible because carbon blocks radio signals.
