Quad 66 is a project to explore the maximum performance that can achieved on 1S brushless quadcopters. It is an area that seems to have been sort of forgotten or skipped over with the surge in ducted "whoop" and 2S+ open propped designs. Given that 1S performance and durability is so dependent on weight, dedicated 1S designs are needed to unlock the performance potential.

The One Twenty is my first attempt at designing a frame and build from the ground up. The goal is maximum performance from 1S in a reasonably durable and affordable build.

The key design feature on of this frame is that the frame and the FC serve as the camera support with some light foam tape to pad and a light rubber band to secure it in place. It is simple, light, and works. Other features include keeping the prop disc area as unobstructed as possible and . Durability comes from keeping the weight down and mounting electronics so that mounts (nylon screws for the FC and rubber band for the camera) that will breakaway or give in a very hard crash.

Dry weight: 28.5 gm
AUW (with 300 mah 1s): 36.2

Frame weight: 3.4 gm

Safe acro flight time about 4 minutes on 300 mah.

Note on the motors I think the Betafpv and Fullspeed 1103 11000KV are the same motor. The Fullspeed however have longer motor wires and will reach on this frame without having to solder any annoying extensions.
