Vtail’s hold a special place with me, more yaw authority than a normal multirotor, and the graceful turns like a tricopter without that pesky yaw mechanism.
The first one was a quad, it was an experiment after converting a standard frame to a Y4, the Y4 performed well indoors, but lacked YAW authority when handling a breeze outside
so, not to be beaten, i remember reading a post on RCgroups about a vtail built by revritchie, so decided to give it a go. a piece of 20mm by 2mm aluminum bar, bent into a 120 deg Vee shape, and the Vtail was born 🙂
and some fun flying at the Hawera MAC field
