Canard and actuation mechanism shown

- actuation gear attaches to assembly here

CANARD

Machined from a single piece of material for simplicity and added strength

ACTUATION MECHANISM COMPONENTS

Springs for deployment and locking mechanism to prevent canard from closing once deployed

Yellow piece here is attachment point to frame

CANARD IN CLOSED POSITION

Internal Frame

-Machined from solid piece of aluminum

-Allows for placement of IMU, GPS, and CPU

Internal Frame

CANARD MOUNTING LOCATION

Mounting bar offset 45 deg from frame to accommodate canard assembly and servomotors

Placement of Canard Assembly

Placement of Servomotors

-Mounts for servomotors currently being designed

-Servos mounted at angle to line up proper angle with actuation gear
