fiberglass specialties, they might have it.

I wonder if he found the site, and whether they had the cowl?

I just checked, they don't, but I wonder if his old cowl can be repaired and a mold pulled from it, that way he can build as many as needed, or maybe market them, or,.....sell on to a aftermarket manufacturer so they can sell them.

I too was going to suggest if he has the old cowl it can be repaired and put back into service. Epo-Grip adhesives (www.epogrip.com) has a fiber reinforced material called Model Matrix that is ideal for fiberglass repair applications. Once the cowl is reinforced and repaired a mold can be made and the cowl can be reproduced.

Hello guysthanks for all the responses, I am trying to fix the cowl my self , so farI reinforced the back with fiber glass material and applied epoxy to it, sanded the outside of the cowl where the cracks are, applied filler to all the cracked areas I am letting it dry for the next layer of filler, tomorrow I am going to sand the filler dowm with 200 grit sand paper and I'm going to apply primer to it, I'm not looking for perfection I just want to have a decent looking cowl, this is going to be my first cowl fix so I hope it comes out ok. again thanks for all the suggestions.

Just for fun, if I were you, I would spend a little more time and make a mold of it, because in the future, if you doink it hard enough to damage the cowl badly, you can make a new one overnight and not be caught with a perfectly good plane and no cowl.

How do you mold a cowl? is there a website that shows how to do it??  That is a great idea since right now there are a lot of pilots that heve Quique somenzini airplanes and no parts!!  I really like the airplane it flies great, but with the parts situation it almost makes me feel like selling it and taking 50%  hit on what I paid.

If you want to learn how to do it for the cheap, read up in composite section here on rcu, if you want a good manual on how to mold parts, pick up harry higgly's "master modeling " book, it covers all the aspects of it, The most exspensive part is buying good quality finishing resin, zap or NHP works well, but I use west or MAS epoxy resins for molds. Then the other componet is going to be PVA mold release agent, it's a liquid thet you can put into a airbrush and spray it on the part or you can brush it on as well. Use a prime coat of epoxy on the part first to help eliminate trapping air bubbles in the molds surface. Then scuff that and lay up heavy glass on the surface, adding wood to the mold will help stiffen the mold, your going to want to make it stiff to avoid distortion of the part being made. You can make the mold 1 piece but it makes getting the part out very difficult, so most people make it a 2 piece clamp together type, this is just a small amount of extra work, but makes pulling parts from the mold 10x easier and less chance of damaging the mold or the part. All you have to do is cut a piece of wodd, hardboard,lexan or anything that is solid to the outline of the molds seam you wish to seperate it at, Prep your part with the PVA release agent and put the outline piece where you want it on the part, fill the gap between the part and the outline with modeling clay and make it flush all the way around, spray the PVA on the lip you just created and resume the process of epoxy or polyester resin surface coat, followed by the glass cloth, when the 1/2 of the part is layed up, remove the outline board you just layed the glascloth up on, coat the back of that lip with the PVA and build up the other side as you did on the first. When everything is cured, drill 1/4" holes along the lip, these will be used for alignment of the two halfs, you can use pins, bolts or a combo of the two, I use bolts, it holds everything tight when doing a part. Now seperate the two halfs and wash away the PVA with warm soapy water and rebolt the halves together, it should, if you did a good job of wetting the surface out with resin and letting it cure, be a exact copy of the part and now you have a mold to layup many parts from. Just don't be stingy on the PVA, you want enough to ensure that it is going to create that protective film so the parts don't stick together.

There's a guy right now selling one with a spare cowl, maybe you could offer to buy just the cowl. It's here on RCU.

all remaining inventory was sold to this company, when QQ closed.

Hiflymodels.com who advertise on RCU in China can supply most QQ spares it seems.
