Trim System


I decided to use and electrically actuated Davenport system for the pitch trim. The actuator I used came from at about $100. It has a 4 inch stroke at approximately 1/2" per second. The pivot point at which the actuator attaches to from the center of the canard the unofficial cozy torque tube. The Davenport plans are available on The Unofficial Cozy Builders WebSite. As to whether I'll need a pulse width modulator until after I get this plane flying.
