You'll decrease your ground clearance if you move your prop down, but of course there are also other things, you can find some answers here, but keep in mind it's only theoretical, hypothetical discussion at this point. http://www.homebuiltairplanes.com/forums/design-structures-cutting-edge-technology/5670-main-wing-position-question-4.html#post46192 Seb

WOW another vivid discussion:) , there are no problems like that on the other aviation related forums like Homebuiltairplanes, vansairforce, biplaneforum etc, it's a pitty that some people don't realize that this type of discussion really repels people, not only from this page but also from canards, but it seems that some people don't care, not my business.

Colin, I think that your first idea were much better, the problem in my opinion was that you were trying to make so many changes at once, new design new materials, etc. If I were you I would first design and build a new fuselage (molded, without autoclave it isn't really necessary for such a plane), I would also build moldless wings per Berkut specification (I've heard that you have Berkut plans and manuals), and in the next step I would eventualy try to build molded wings. You could build a really nice fuselage, I did a short sample for guys at HBA (attachments) it was only a sample and of course you can make a better one, (I raised up an engine about 7" like in the Stagger Ez). Please note it's only a sample and I'm not going to build it. Take care Seb btw renderings made in Solidworks

Theoretically yes, but what a point? http://www.proxyaviation.com/media_photos.html#

Wow I just checked my Long Ez plans, I haven't seen them for 6-8 months. I'm not into Long Ez any more. Seems that, there is only UNI in the wings, I'm wondering where is that 7725 come from, hmm

Thanks Colin, I completely forgot, about 2-3 years ago there was a discussion at Canaraviation forum about the Berkut wings Layup, Richard Rilley said that fabric was laid at 30 and -30 deg, unfortunately he remowed all his post there, and because he passed away last December I can't ask him about it. I remeber that he said also, that the Berkut had 8 layers of fabric in the shear web, not 6 like the Long Ez. That's all what I remember. Seb

I know they don't/didn't use 7725, but I thought that they replaced glass BID 7725 with Carbon BID 282. So I understand they used 3 layers of UNI, first at 45deg, second at 0deg, and third at -45deg. Do you remember exact order?

Isn't it carbon uni fibre? Not prepreg.http://www.hexcel.com/www.hexcel.com/Fabrics_DataSheets/716.pdf http://www.aircraftspruce.com/catalog/cmpages/unicarbongraphite.php I've heard about 3 carbon BID layers insted of two 7725. What did they use in place of the 7725? Was it 282 or 284?

I remember about Cirrus, actually was one more similar design, French Orion 801 http://oriong801.free.fr/gallery-26718.htm There is one common thing for all these desgins, all of them failed sooner or later. Seb

Not bad but it isn't an original idea, that plane is similar to Prescott Pusher, Pushy Cat, and few oters. And it isn't real canard it has h-stab. Anyway thanks for link. Seb

Got it thanks. Seb

TMann if you are looking for something like "homemade oven" try these links Extremely simple and cheap http://www.privatedata.com/byb/rocketry/composites/ovens/Airframe%20Composite%20Curing%20and%20Post%20Curing%20Oven.html http://www.jrockdale.com/curing_oven.htm This one is really nice and big but is also $$$. http://www.dpcars.net/dp1v8/db.htm Seb

Could you give a link to that forum? Seb

Isn't it also about glass, resin ratio? Seb
