Gotcha, Harry. I had CG concerns in my Tailwind because the wings are wet (just under 50 gal.)which places the balance point a bit father aft. So it sounds like an O-360 wouldn’t be a problem..... Thanks. I’ll contact Van’s tomorrow and see what they have to say about the issue.

FWIW, I have the old small tail on my RV-6 tail dragger with O-360 and fixed pitch (Catto) and it slips just fine. Sure, you can't add full power until you get a little speed for full rudder authority on takeoff, my feeling is so what, makes me think I'm flying a Mustang (in my dreams!). As for tail wag, I have flown an RV-7 tail dragger with the large tail and it wagged just as much as mine does in turbulence.
Now, having said all that, if you are given to doing intentional spins, go with the large tail for faster spin recovery. I have never spun mine, and have no intention of ever doing so.
BTW, R.C., if you are building a tail dragger and plan on a fixed pitch prop, especially if it is a light composite prop, you are probably going to find that you need to be concerned about aft CG issues. The heavier O-360 might actually be a boon in that respect. Just passing on my own experience for whatever it's worth.

I have an O-320-160 in my Tailwind and was considering an O-360-180 for the -6. I’m only 120# after a heavy meal, and soaking wet, so pass payload wouldn’t be an issue. I do occasionally execute aggressive slips on approach when necessary.... was this an “AD” from Van’s? Maybe I should consider another O-320-160......

First they increased the height of the stab and made a larger counterbalanced rudder, then they came out with the 7 with an even taller stab (I think) and quickly went to the riveted trailing edge rudder for better spin recovery.
What I've experienced with my 6A and small rudder is a little hunting in turbulence and not enough authority for serious slips. Less wetted area makes for a faster airplane, if that's what you want. Marty is probably right about not using full power on the takeoff roll, but it'll accelerate and break ground with very little power and then, with more airspeed and control authority, you can bring in the rest of the power. Even an O-320 fixed pitch bird climbs just fine, not 3000fpm mind you but just fine.

What’s this about a larger tail for the -6? I’m currently working on my Fuse for the -6 and it’s a Tail dragger. I have the original Tail Section that I built several years ago. How critical is this new tail mod for the tail wheel version? Is this info on the web sight or can it be found here on the forum?

You might want to advise your buddy that Vans made a larger tail for a reason: especially if its a tail dragger or he puts in an engine larger than the 160 hp.
Even with the Rv-7 larger tail, I can't add full power until the tail is off the ground...

Has anyone out there got or know of and old style Vertical stab and rudder for an RV-6, kit or any stage of completion, that they want to part with. I think a -4 would also work. A friend of mine is building a -6and does not want to use the new larger RV-8 style vertical tail.
Either reply here or call Bob Gorman directly at 408-828-6727
