Gyronut, even though you you addressed your last post to Hal, it seems you were talking to me so Ill reply.
In your first post you stated to build a gyro of standard design, and learn a few things. I already have a standard gyro, the converted ugly stick, which is a tractor, side by side layout.
The design Im working on is a coax pusher.
Dont know where you got the tandem bit from.

Anyway thanx guys, Ill steer clear of the v-tail for now.
