Good morning everyone. Planning on going flying this morning. It's 50, no wind, and clear. The sun will be up in 10 minutes. Now the question is, which plane to take ???

HI Scottie,

A sub-fin on a V tail plane, has to look like the letter Y. Were gonna have to have a board meeting on this one.

Yep, looks like a good day to fly here also Bob. 86F and no wind. It's 7:30am. Going to be some real boomers out there in a few hours.

A couple 'pro' for the V tail that have won me over.

Less chance of landing damage,
Tend to lift tail on ground loop landings
I can stack three fuses on a wall hanger
If one servo takes a dump you still have some up/down-right/left control
Less chance of newbie handlaunching and breaking the elevator off with the back of his/her head.
They tend to have better control on a winch/highstart.
Easier to build. JMHO after doing it for decades.
Easier to trim for flat turns, JMHO after doing that also for decades.
And, number one reason IMO,,,, They look cool

So, can I join the club?

HI Tbird,

You seem to be in love with V tails. Try and rememebr that this is the NO V Tail club. I suggest that you start a V tail club on your own, for people who love V tails. You'll have many more members than we have here.

Bob, I believe you said you did have a V-tail once. Technically, for you to be a member, shouldn't this be the "No More V-Tails Club"?

Your right Dave, my Omega HAD a V tail when I got it. I later sawed it off. It's hanging on the wall now as a reminder to me about V tails. It's to late to change the name, all the stationary is printed up. Smile.

Yes, printing costs can get expensive. I would join up, but it would be a short membership. I haven't glued the V-tail on my Chrysalis yet.

Actually the plaid pattern on the logo was from a tartan website that will make kilts for you based on your family sir name.

I definitely don't qualify as a member of this group, but I figured I should stop by from time to time just to keep the discussion honest.

Sounds like you tried to use some that were designed by the "projected area" method, which results in a seriously undersized V-tail, with poor spin recovery characteristics, among other things. When designed properly, with the same TOTAL area as the equivalent T-tail or conventional tail, their spin recovery characteristics are, if anything, better than the other types. In the rotation of a spin, there can be partial blanking of the "lee" half of the tail by the "windward" half, and that results in a natural nose-down characteristic that breaks the stall and stops the spin. I've demonstrated this consistently with spin tests of indoor free-flight models (see attached photo for a mobile I made from the first thirteen, the first of which dates back to 1967).

but mainly because they're a pain to store and transport. It's pretty easy to make a conventional stab bolt on, but Vs are a pain in the proverbial.
Again not really so. I's no big deal to make a bolt-on V-shaped platform for a V-tail (see the Chrysalis build thread for some sketches). Also, there is less need for a bolt-on V-tail, because a V-tail will nestle nicely into a corner, and you can also stack them together, nesting with each other, something you can't do with an assembled conventional or T-tail. In actual practice I've found storage and transport of a bunch of V-tail models to be significantly easier than the other types. And yes, I do have quite a bit of actual experience with that.

Do you have the URL for that? I'd like to see what they list for my family's pattern. I've seen a couple different ones from different sources, and they don't all agree.

I can get it for you on Monday. I have the link to it on my laptop and I left it at my office over the weekend. I try hard not to bring work home with me on the weekends.
