Hi all,

Are the Empennages for the -6, -7 & -8 totally identical and are
therefore interchangeable from one model to the other??? Just
wondering..., so anyone know for sure?

Thank you, Konrad

The -7 and -8 have the same Empennage, but the -6 has a different one. The -4 and -6 Empennages are much smaller than on the -7 and -8. To my eye, the 4/6 fin-rudder is a little too small, and the 7/8 fin-rudder is a little too big. That being said, with the IO-390 on the -8, I'm often wishing I had more rudder authority during landing. So, it may be visually too big on the 7/8 already, but it could be bigger! Smile

Hi all,
Aren't the various fuselage width's at the horizontal stabilizer area-, as well as the attach points themselves for the horizontal stab different between the -6, -7, -8?

There is someone marketing a finished empennage on Barnstormers, saying "...it can be used on either the 6, 7, 8... and it made no sense to me / I was not sure on that!
Here is what he said to me in an email: "The empennage can be used on any of Van's aircraft models of 6, 7, or 8 : or 6a,7a or 8a. Charlie" Is he correct in that statement?


On the other hand, I do have a "spare" built / late version -6 Empennage (with tall, counterbalanced rudder), so I wondered if it would work for the -7 or -8 guys as well???
Anyone need one, either with or without a nearly virgin Wing kit of the pre-drilled kind, maybe even match drilled? The spars are assembled already!
Cheers, Konrad

match the hole in fuselage bulkhead. Also had to redo the tail fairing to make it fit.

I started my build in 1999 when the 6 was beginning to be phased out. I ordered the QB kit and the empanage was not the original 6's configuration, both the rudder and the elevators are counter balanced and the VS and rudder are much larger. I am thankful for the larger set.
