Sub250 Huma20 O3 Bottom Plate — 2mm Carbon Fibre

Drop-in replacement for the Sub250 Huma20: this Huma20 O3 bottom plate is a 2mm carbon fibre bottom plate built for sub-250 builds and DJI O3 compatible frames. Fits Huma20 O3/O4 layouts and keeps your rig tidy (yes, we padded SEO for safety).

Why You Want It

Because a flimsy bottom plate is how you lose a VTX and a weekend. This plate gives a low-profile, rigid base for the O3 Air Unit and battery straps, tidy cable routing and crash-resistance where it counts. We’re selling this — capitalism, the build community, and your need for fewer repairs made us do it.

Specifications

• Material: 2mm carbon fibre (stiff, light, not magic smoke proof).
• Thickness: 2 mm (standard Huma20 spec — thicker where it matters).
• Fits: Sub250 Huma20 O3 / O4 frames (95 mm wheelbase) — mounts to the usual Huma20 stack layout.
• Mounting: Designed for common AIO/FC stacks and tidy O3 air-unit routing (yes, that means less Velcro soup).
• Weight: ~5 g (estimate — we guessed so you don’t have to; actual depends on trim and screw kit).
• Finish: CNC cut with chamfered edges (no sharp bits to snag your lipo strap).

What’s in the Box*

• 1 × Sub250 Huma20 O3 bottom plate (2mm carbon fibre)
