Greg 's VTOL settings. Tricopter "Home made" - Page 26. New tricopter frame design. Yes - This is an AP tricopter - The yaw mechanism as shown above would be controlled by a servo - I just received word that the 1/8" plywood version has just been laser cut so I should have some actually photos early next week - The plywood version should glue up easily with CA - will know more soon - Mike.
