Details

A compact 3-inch freestyle frame aimed at lightweight builds that are easy to carry and fly in more places.

T300 carbon fiber and a one-piece molded layout help keep the build light while improving everyday crash durability.


The integrated battery roll cage helps reduce battery movement and protects the balance lead during crashes.

Choose the video system that fits your setup—room for analog, Walksnail Avatar, DJI O4, or a no-VTX build.

Dual motor mounting patterns make it easier to reuse motors or upgrade without changing the frame.


Everything needed for the frame build is included, with hardware and parts varying by analog, Walksnail, or O4 version.
