Rev750

From rev0wiki
Jump to: navigation, search

The rev750 is a custom designed + built ~850mm motor to motor distance octocopter with simplicity and durability in mind. It uses 8 unique FR-4 plates, 10mm carbon-hybrid booms (as described here: https://www.fortisairframes.com/how-to-carbon-hybrid-booms/) and 10mm basswood, held together with M3 screws. It uses a clean/dirty plate system, with the motors/ESCs on the vibration isolated carbon fiber frame, and the cameras, flight controller, and battery (for weight) below. It is designed primarily to use a G1W dash cam as the main flight recording camera, but has the mounting option for a brushless gimbal + GoPro.
