Mark4 10-Inch Arm Frame Part

A direct replacement carbon fibre arm for the 10-inch variant of the Mark4 long-range frame. Designed to get macro-quads and heavy-lift builds back in the air after a hard impact, this single replacement part allows for isolated field repairs without tearing down the entire centre chassis.

Key features

• Direct drop-in fit for 10-inch Mark4 frames (typically featuring a 427mm wheelbase).
• Precision-machined carbon fibre construction to support the high torque and payload weight of macro-quads.
• Pre-drilled mounting slots accommodate the larger 16x16mm and 19x19mm motor bolt patterns standard on 28xx to 31xx stators.
• Isolated arm geometry permits single-arm swap-outs by loosening just the inner chassis bolts.

When replacing broken parts on a 10-inch Mark4, ensure you are matching the correct wheelbase arm, as 10-inch kits typically utilise thicker carbon (often 5.5mm) compared to the standard 7-inch and 8-inch versions.
