You beat me to it. But I think for the speed of a gyro, it is fine. Then again, a V-tail usually does not have enough horizontal volumn. To achieve the same effectiveness, you need a much bigger V-tail.Getmobile in some circles the old bonanza v tail was referred to as the widow maker for doctors.
To Okaneco ,thank you again for following up on the "twinstarr" if you find anyone with plans i would be interested, if anyone has any photos of the rudder, tail v section in detail preferably, under construction would be better so i can view the structural design.No plans, that I know. I do know where at least 5 Twinstarrs are located. There are 4 in our club
