I talked with Jon at Sun & Fun about the UV Smooth Prime. In addition to the UV addition, the chemical composition of Smooth Prime itself had to be modified slightly to achieve a complete mixture of the two products. Smooth Prime itself came out better than before. For you guys who are trying to get rid of pin holes and the like, Smooth Prime is the ticket. After applying this stuff with a roller (you heard me right, a roller), sand the stuff and you have a great finish. It is water based so the water evaporates, leaving only the material which sands like there's no tomorrow. Once again, I will be putting on forum and will probably end up with enough material to enable lots of people to actually participate in a weekend workshop using a lay-up and going through the Super Fil, Smooth Prime and the formerly cruel process of sanding to get a final product that would be ready for paint over the course of the two days. BTW, the girl in the car that ran through my hangar had to have 400 stitches to reattach her scalp. She bought the passenger prop tip as she was thrown from the car.

I've looked through the plans extensively, and have several questions. However, I'll keep this email to one question: The 'boat' is comprised of longerons and cross-members. Then the plywood skin is added. After everything else is done, you glass over the plywood to get a smooth surface. Would it be possible to simply eliminate the plywood? I would think that you could foam between all of the cross-members and just glass the skin to the boat. Yes, I realize that the skin takes most of the stresses. But I am assuming that the fiberglass, when bonded to all of the members, might be capable of the loads. It would sure cut down on the weight (allowing the addition of some heavier components in the rear of the plane). Sure, you'd have to watch your cg's. It might not be feasible, but I'm trying to figure out some ways to improve on the original design..... -Aubrey Dunham San Antonio, TX _________________________________________________________ Do You Yahoo!?

I've had it full throttle on the runway for maybe 7 or 8 seconds (20 times) but the extra ram air flow from actually flying was what it took to rotate the needle.  If you use a POSA, make sure yours doesn't rotate on its own.

But a heavy accurate wood form ( called a "strongback") has to be made to secure the foam while the glass is being applied. Then the fuselage has to be heated in the sun under a plastic sheet ( called "postcuring"). It may not be less work. But look at the builders' websites accessable through American Affordable Aircraft's homepage at to see what I am referring to.

Would it be possible to simply > eliminate the plywood? snip The glass over plywood is optional, and I think that most people do not add it due to the additional weight. In the structural analysis, the spruce members carry the tensile and compressive loads, and the plywood carries the shear load that is generated by the tensile and compressive loads. A single ply of 6 oz/square yard fiberglass is approxiamtely as strong in shear as a layer of 3/32" mahagony plywood, BUT there is no margin for manufacturing errors. If you had one ply of glass instead of the plywood, and you sanded the surface too aggressively, then you would run the risk of failure. Two plys of 6 oz glass would be an acceptable alternative if the spruce structure is unchanged. If you go this route, you end up saving almost nothing in the overall weight. -- Don Reid Bumpass, Va. mailto:donreid@erols.com KR2XL at http://www.erols.com/donreid/kr_page.htm Ultralights at http://www.erols.com/donreid/usua250.html ---------------------------------------------------------------------- Subject: Re: Little bit of KR2 info I stumbled upon.

They come in many sizes and shapes. The can be ordered from JEGS or other Auto Speed supply catalogs for $100.00 + or -. They are light and are used in dragsters where weight is also a factor. I am referring to your Header Tank. Haven't found a size for wing tanks myself I had already fabed them. The total size should be based on how long you want to fly with reserves accounted for..

The output of the first set goes to the top of the second master cylinder, then out of the bottom of it to the slave cylinder on the wheel. In fact I have two sets of the earlier models of the Matco cylinders ready to go onto an Avid Flyer I'm rebuilding. The older version were MC-1 (predecessor to the MC-5) and MC-3 (same as a MC-4) Jeff Scott - Los Alamos, NM mailto:jscott.pilot@juno.com See N1213w construction and first flight at http://www.thuntek.net/~jeb/krjeff.htm ___________________________________________________________________ Get the Internet just the way you want it.

For those that are adamant about not having fuel tanks in the cockpit due to fear of fires like this, please note that the RV designs have the fuel in the wings. On the other hand, I watched a friend spin his Pitts into the ground hard enough to break the plane apart into many pieces, but no fire from the fuel tank which was in the cockpit and had the landing gear driven up through it.

I fine sanded the plywood, shot it with sand 'n fill primer, then scrubbed the primer in with laquer thinner to fill the grain and staple holes. The finish is every bit as smooth as if I had applied deck cloth then sanded and filled until smooth.

Any >recommendations for this? > >Thanks, >Gary Hamilton >Georgetown, TX My fuel tanks were fabricated with 1/4" lastifoam with that I laminated with a layer of 4.4 oz glass on each side before I marked them and cut them up to build the tanks. I used a wire brush to "eat" the foam out from between the two layers of glass about 1/4" deep along the edges, then floxed the corners together. Once the tank was shaped, I did a lay up of glass on the inside of the tank with an extra layup of 6.6 oz glass on the inside and outside of each joint. Next I floxed and glassed in the tank baffles to stop the fuel from sloshing and to add some rigidity and strength to the tanks. The wing tanks I built in place right side up in the wings then built a top that I floxed and glassed in place. The header tank I built upside down on the top deck, then built a separate bottom and floxed and glassed it onto the tank. Mine were built with Safe-T-Poxy, which is no longer available. If I was doing it today, I would build them of VinylEster. So far I have 185 hours on the plane and just over two years of age since it was finished. I have had one leak so far and that turned out to be a bad gasket under a fuel probe and that was in the first 40 hours. Building the tanks of foam and glass was pretty simple compared to much of the rest of the construction.
