Tall tail

Tall tail

On the subject of tail effectiveness with regard to torque-cancelling and spiralling slipstream, remember that the LW tail on John's machine has a full-span horizontal section centered in the propwash. This acts as a flow-straightener in the same way as a full-span vertical surface would.

Ron H. I have flown several gyros with short tails. None could hold a candle to how nice Johns Herron T tail flew. If I didn't want a tall tail, I would have yours in a heartbeat!

Ron,
Mr. DeGraw is the one who builds the tails for now. I doubt Dad had anyone else do the work.

Well unless I am missing a step in the process or something, then Dick messed up drilling my holes!!!! I know I spoke with your dad about it when I was building the machine, and I am pretty sure he told me these holes were drilled at the factory. It isn't a big deal..... Ask your dad about it. Maybe I am wrong here.

Say Ron:

Does your post about your tall tail mean that it wasn't built with a twist to counter-act torque on purpose? I was curious to hear more about it and see pictures if so and kept forgetting to ask you about this...

Yes as far as I know the tail was supposed to have been built straight. It is off by a quarter of a inch. It isn't a big deal.

See what you started Ron!

Now everyone is going to want a tail with a twist in it!

I guess Scott. John Stevens brought it up.....

just my two cents, but twist in the horizontal is not needed to counter P factor when your using a tall tail with stab in middle of propwash like on a Dominator tail.
