I have mine at 94-95mm back AUW=83oz. Just measured CG this last sunday after Bob - Bobalew flew it. V-tail has just a small bit of up trim, but I am told this is sometimes normal for V-tails. The original one (larrycrash test dummy now has it) has a bit of up V-tail also and flies good. I will get a picture of mine tonight for you.

Bob seemed to like it as is. He commented it may be just a bit nose heavy.
He took the Vulture up and up in light air and when I got the plane back, I fell out of the thermal he had. He did the plane justice, difference between compitition and casual flyer. He can comment further if he see's the post.

I would move your CG forward and go with a bit of up V-tail for flight.
I have to say that after flying the Vulture, I was pleasantly surprized. It is very easy to circle in thermal flight, moves when you want it to, and lands well. But what really surprized me was how well it floats. I believe the model I flew was something like 82 oz. It just goes to show that maybe we shouldn't judge a plane on weight alone, but on overall handling.
A very forgiving sailplane.

This is the trim setting Bob used while thermalling last sunday. I have not move the trims since Bob flew it. Powered the TX-RX up for pic, trims saved in 14mz memory. I had a bit more, but Bob did a little tweaking for me.
Thanks Bob.

Is it the same or even with the root?

So I have finally gotten my Vulture finished and flew its first flight last Thursday.

I used many of the "settings" discussed here as a start and I spent the morning tuning it.

I'm not done yet so I'll say the following is very subject to change....

Total AUW came in at 76.7oz.... CG at 95mm

Pro's: It slows down really nicely with its big flaps for landing.
My current settings have is thermal turning really smooth.

Con's: The decalage is definitely off. Too much up trim for level flight. I'll be adjusting the v-tail alignment pin holes over the next couple weeks to get this corrected.

I want to thank Kilwein for his build information as he inspired me to build a similar nose cap for my plane. I'll be looking to add a ballast system like his soon too.

Most of the build was "standard" so I won't bore you with that.... I did use 761 servos for the flaps and 809's for the ailerons. Also used a 5 cell 1700mah battery pack.

One place I did significant changes that might be of interest to many builders is the servo tray.

I did a lot of work to redesign the servo tray to get my servo's way up in the nose to lower total overall weight. It's a two piece tray system.

Below are some pictures of the final servo tray area and also some details of the build in progress.

I like to call this servo tray design the "where's the servo's" modification.....

Hi Radian,

Thanks for the comments. Glad the thread helped.
Like your servo tray mod, it hides the servos in the nose and looks like it reduces the AUW weight a bit.
That green nose is going to be seen for some distance.

Guys - I've been reading the whole thread with some interest.
Can you please clarify somethings for me?
I think from reading the previous posts that the model is made by MVM Model in Bulgaria which is something to do with both Vasil Milev (Vasil_M) and Nikolay Peichev. I get the Skip Miller / Cody Remington involvement in part at least but I am trying to determine whose design it is, how it is doing in competition and what is the wing section (if that has been made known).

Many thanks in advance.

Hi Slopetrashuk,
The wing section is MVM model (Vasil Milev) design.For now I will not give more information.
For the competition performance-Cody is the best testimonial.

I just won a Skip Miller Vulture sailplane from one of the RC clubs that I am a member of. I look forward to having the time to read this thread completely because I have lots of questions. Thanks to everyone for taking the time to report your progress!

Congrats on the win! Let me know if you need any help with setup or anything with the model.

The Vulture is a great plane. You are going to love it.

Yes, but he's dead now.....

Anyway, I'm sure that a build thread of an E-plane will be received well in the electric sailplanes forum, that is what it's for.... A link to it in this forum would be handy for those inclined.
That's my two cents!

Hi Tony,

Feel free to leave the link to the E-build for who ever is interested in either style.
I feel both have a place.
Will be checking your build out as it progresses along.

I can say this "a certain flyer" likes to fly my AVA-E.
He was on the sticks today as a matter of fact.
