Get in touch with this guy and ask him about his aircraft performance. I think you can get his email from Mark on the Cozy mailing list.

which guy? there is only a picture.

This is the only exceptional 3 view drawing I have found. It's very good though.

It doesn't have dimensions:(

Ask Berkut flyers. Expect to get what - 10-15 kts better than a Long-EZ with the same power, Richard? Maybe 200-220 kts with an O-360 burning 10-11 gph, and the 250 kts at 14-15 gph with an O-540? That sound in the ballpark? These would be TAS's, at altitude. Richard (or others) can fill you in better on the #'s.

 

The rudders are ON the winglets, but there are modifications that may be done to the way that the winglets are mounted to the wings that can substantially decrease drag.

 

Also, join the CSA, get the newsletter and read ez.org.

This was very helpful thanks.

Ok, well thanks to those who have been answering questions and advice.

What you have to understand is that most of us are either very busy building a plane or very busy flying and maintaining one we already built. We try to help each other out when we have problems we encounter. Your being lazy takes up mine and others building time We dont know if you will every even buy a set a plans. I have over 800 hours of build time and maybe that much in reasearch time. I only bother to ask questions when I cant find the answer. Lazy is a really poor excuse if you want exsperienced help off of this forum. My .02 Steve Build on

IOW, "I'd like someone else to do my work for me". Do your homework, then ask questions.

Well, I guess you guys don't understand my sense of humor then.

If nothing else, ask where to find the information you seek. Which info you were given in my first response, down at the bottom of the posting.

I have spent the last few weeks online looking for stuff. Now, I am asking questions I can't find. I have been asking for where to find information.

grab the Berkut 3 view that's floating around on the web

And there's that whole the-engine-is-vaporware thing, too.

 

keeping the prop far enough forward so you don't get a prop strike on landing, and preferably with less than an 18" prop extension. (the gyroscopic forces get huge when you get that long".)

Alright, and is it possible that a 3 blade (with a shorter diameter) could help prevent a prop strike? Would a 3 blade add too much mass to the whole system? Not a chance I could lengthen the landing gear a little more? Would theses gyroscopic forces add more turning tendencies?

I think the restraint shown here by a 50 something professional who built the Berkut, is just absolutely amazing.

My .02

I know he's built one and has experience. Why would he need to restrain himself? I am asking questions because I have no idea. I would like to know everything there is about this plane, and the only way to do that is to start searching and asking. I'm not trying to impose my ideas. I'm trying to see how they would fit.

My bad, Richard....my point was he didn't understand your level of involvement.

I recognized he built the plane, though I did not know what avenues he took to get there. That's what I'm trying to figure out. There's no gain by touting knowledge from others, so please, keep the flaming to yourself. I mean that in the nicest way possible.

If it ever comes to exist (and I would bet a year's paycheck against it) it won't fit well on a Berkut. You'd end up with the cowls going straight back from the firewall, curling around the cylenders and stopping around the prop shaft. The DeltaHawk is closer. But really, Berkut was designed around the Lycoming.

Well, I guess mine would be an "experimental" a/c then, like all the rest;)

I would have to do some research and modification to the cowling, right? And the prop shaft could be extended to lengthen the cowl and streamline it a little more.

I would like to add that I have spent some time looking at websites online. The most helpful one I found was Berkut13.com. If any one has more/better stuff, let me know.

I don't like searching through all the forums because a lot ends up being drivel. Plus, it's time consuming and I would question some of the credability of the posts. That aside, I have learned quite a bit from the forums.

The only point where I disagree with Marc is on the fuel. Later airplanes, with molded wings, put about 15 extra gallons in the wings just outboard of the strakes. Beyond that, you could put about 50 gallons in underwing pods and for record attempts another 50 in the back seat.

 

As to how to get one - they're rare. I'll sell you mine, but it's REALLY, REALLY, REALLY expensive.

So, helpful to know before buying! Thanks!

You won't get 250 kts. on 10 GPH. Those are independent #'s.

Then you should know to ignore it. It's no different than claiming that you want anti-gravity, and you know it's not quite available yet.

Oww.

The Zoche wasn't available when I started building in 1995 (even though it was right around the corner), and it isn't any closer to being available now.

Sure. If it's not the Zoche, then another diesel.

Nope. Not a chance. Brand new plane.

Ok, so I need supplemental oxygen for high cruise?

There are some methods, involving winglets, cooling drag, and some others. Web searches will find some of them.

Doesn't the Berkut have "winglets"? They're rudders, right?

That would be Richard Riley - one of the principals in Berkut. He won't tell you anything substantially different than what I tell you, though, at least with respect to these questions.

Awesome. That's a good start.

Go right ahead, if you can find an unbuilt kit, but make sure your expectations (of yourself and your travel needs, as well as the aircraft) are reasonable - not pie-in-the-sky.

sigh...I knew I'd get flamed. Did I tell you I'm new to all this stuff?

Then spend a LOT of time reviewing the archives of this forum, as well as the COZY mailing list, the canard-aviators mailing list, and any and all web sites that you can find. It's all been asked before.

Yes that's true, but I'm lazy. J/K. No, I am finishing up finals and I'm buying a home. I don't have a lot of time to seperate the wheat from the chaff. I am looking for direct answers to some of my questions. Ok, I guess I am lazy...Hopefully, this summer I'll have more time.

Alright folks,

Let me start by saying, "I am a noob." Now then, I am intending to build a canard. I want it to be as fast and light as possible. I am a big guy and I'll need a little elbow room, so if I want a two-seater (and I do) I'll have to make some mods.

That said, I have looked at the Berkut. I'm not aware of any other aircraft that are competitive to this. Sorry, EZ guys, I want more speed. If you know of any, speak up! I don't wan't to drop in a bigger motor to go fast. I want a slippery plane.

I really like the stats I've seen on this bird. 250+ knots, less than 10 GPH, 19:1 glide ratio!!! It's my kind of plane. Also, I am considering the Zoche diesel, because of it's (stated) abilties. Yes all of you flamers, I know it's vapor-ware!!! I've posted on this thread:

http://www.canardzone.com/forum/showthread.php?t=1571&page=2

With the combined efficiencies of the a/c and engine, I would like to make some long and fast X-C flying with my wife (no dirty jokes please), so I may need some bigger tanks (Trans-Pacific?). Could I make integral modifications (even 5-10 gal worth) to the plane or would I have to buy/build external tanks?

Also, can this plane be pressurized? To what altitude?

Is there any way to give the plane less drag? Maybe through the canard, or else what?

Who has the most experience on this forum with the Berkut (or any other comparable)?

Financial considerations aside (really), what would be your advice on building this plane?

This is my dream to build. Please, don't bash me. I am excited and enthused to design and build something of this caliber.

Some other factors to consider:

I'm in college and I have 2 years of school left.

I have no kit building experience.

I enjoy building/designing.

I love to fly:).

I'm willing to listen and learn.

I need your help/experience.

anybody know about the progress of this motor? I want to put it on a Berkut to utillize its full potential. Is it still vapor-ware? hope not.
