Legato

Legato is a 340mm 7" long range frame. It's designed to use the cinelifter batteries you already own, 6s packs in the 4-4500 mah range. Arms are 8mm thick. The nose assembly has 3 Hero mounting options for no props in view even for negative tilt. The linkage mount fits Hero tabs, so any camera or accessory that uses those tabs will fit.

Base Kit includes the frame and nose assembly, with no printed parts. Battery pad and 2 extra long straps included.

Legato can be made waterproof with an optional 3d printed skirt and an aluminum heat sink for your esc.
