Sub250 Nanofly20 1S HDZero Micro FPV Drone (ELRS)

Overview:
The Sub250 Nanofly20 1S HDZero is a lightweight 2-inch micro FPV drone designed for controlled freestyle flying in and around whoop race courses or pulling off stunt maneouvers. Built around an 88mm wheelbase via a compact carbon fibre frame to deliver precise handling and resilience.

Powered by 1002 21000KV motors on a 1S platform, this version prioritises responsiveness and efficiency within a lightweight design. The highly integrated AIO flight controller combines the FC, ESC and receiver into a single compact board, helping reduce weight and size.

The quad is equipped with the HDZero Whoop Lite VTX and Nano Lite camera, providing low-latency digital FPV performance with a consistent quality image feed. This makes it particularly suited to pilots who prioritise precise control feel and predictable video behaviour over maximum image resolution.

The Nanofly20 1S HDZero is compatible with LAVA 1S batteries, which deliver higher energy density, less internal resistance and significantly improved discharge performance compared to standard 1S LiHV packs, see 'Related Products' below for options. The 1S Lava II series batteries are also available *here*, the entire range will comfortably fit under this whoop. To charge multiple 1S batteries simultaneously, we recommend the Vifly WhoopStor 3, available *here*.

With its sub-250g weight and efficient 1S power system, the Nanofly20 1S HDZero offers a balanced quad for indoor freestyle and technical flying where outstanding control and manouverability win everytime.
