I'm just finishing mine, it's in the paint shop finally, but after 18
years fo work. (Glasair) I keep up with another homebuilder friend of mine out on the west coast in Stockton, which is a good GA airport. Lots of homebuilts under construction, good infastructure for GA on the field, etc. He told me no one is building composite planes out there anymore. It's like the word is out on how much work and how long it takes to build the things, and it's becoming a thing of the past. I just wonder if that trend is just in that area, or nationwide? I know in the present economy, homebuilts are probably down anyway, but what he said about that trend started before the economy tanked. If not many are building composite planes, then the only other ones I would think are being built are metal (RV designs) and tube and fabric. I doubt wood designs will come back, they're just as much work as composite designes are, or more. (I've got one of those too ![]() Rich |

Most of a wood and/or fabric project involves far less fumes to breath than composites! Just my $0.02 Peter Our club has both composite and aluminum. Frankly, the composites get more air time. A lot of our members have built and bought planes. At least the consensus of our membership is this... It seems to take about the same amount of time to complete either type of aircraft. With the composites, you get the advantage of getting to a point more quickly where you can sit in something that resembles an airplane and make plane noises but it will take you longer to do the finish work. With the aluminum planes, it takes you longer to make plane noises, but the finish work doesn't take as long. Finished price seems to be fairly equivalent for similar capacity and performance. You might see more aluminum planes because there are a lot more aluminum companies. I would also guess that, from a manufacturing standpoint, it would be less expensive to set up shop to produce aluminum kits than composite kits. Having never bought equipment for either, that's just a guess. But metal working machinery has been around for a long time and you can get some good deals on used equipment. You can also produce a lot of different designs with the same equipment. For composites, there are the autoclaves and forms, and all the other stuff. The material handling needs are a lot more exacting with composites and quality control may be an issue that adds expense. For a builder, it all comes down to preference on airplane style you prefer and the materials you're comfortable working with. Personally, I've always been intrigued with flowing lines and compound curves - they just seem more organic to me - which makes me lean to composites. I've also spent a lot of time in my youth working on the family boats. I got really tired of hammering rivets after a long day of skiing. And when we made the switch to fiberglas boats, I learned other lessons. For instance, I learned that you don't want to try to lay fiberglas when you're swimming in the water and the boat is suspended over the boat well in a sling. Resin floats and WILL harden while floating on the water...DAMHIKT... ;-) |

When a part is completed, , no corosion protection needed, no more moisture protection. No special storage requirement too for resin and fabrics. by -- « Si tous les poètes voulaient se donner la main, ils toucheraient enfin des doigts d'auteur! » Philippe Vessaire Ò¿Ó¬ |

(I've got one of those too ![]() Rich Rich, First I would like to congratulate you on finishing your plane. I am also building a KIS Cruiser and have been working on it for almost 14 calendar years. I suspect that life has gotten in the way of your completing your project earlier as it has with my project. The fact that you continued to completion says a lot about you and your dedication to seeing it through. There are several issues that I have repeatedly seen with composite aircraft that I have not seen as frequently with the RV's which seem to be the dominate kit on the market. The first has to do with quality of the supplied molded parts. Because of the low volumes most kit manufacturers have to deal with, they have little incentive to invest in the best quality molds and the refinements needed to make parts that require little additional work prior to assembly. This means that the builder must spend substantial time in cleanup, fit and finish. Every composite kit company that I know of still has extensive labor involved and can not automate their processes like Van's has done with much of his fabrication process. The second is builder enhancements (modifications) to the original design. These changes can be anything from a minor change to some major redesign to the entire airframe. I have seen hundreds of RV's over the years and few of them make anything beyond cosmetic changes and those that do are usually experience builders on their n'th build. I know in my own case that I have made dozens of changes, mostly minor, that have cumulatively added several hundred hours to my build time. If I had exactly followed the original plans...I would have been flying already. There are many more differences but the last that I will hit on is Finish. That is where almost every time gain a composite builder may have achieved in the construction process is wiped out. The standards for finishing a composite aircraft are unreal and really totally unnecessary. With a few notable exceptions the builders of the RV's will complete and fly their planes with no paint or will spend little time and effort beyond having a paint shop spray them. That's not saying they aren't great looking planes but they don't get anal about a rivet showing or a slight ripple in the wing or fuselage surface. That is expected when working with metal. The glass builders seem obsessed with producing a finish that has the quality of a fine mirror. Gawd forbid that the fabric weave should happen to show through. Having said that, I must admit that I have already got a couple hundred hours into the fill and sand process that preceeds the primer and more fill and sand. I just can't help myself. Finally, there are still a lot of composite kits being built. Lancair, Glassair, Velocity, TeamTango, CompAir, and a host of others come to mind. They will continue to be a major player in the market but lets also admit that when it comes to great, affordable, and buildable aircraft...Van's Aircraft are the dominate company as of now. |

I agree with all you said. And I didn't enjoy breathing the fumes
myself all those years. Plus, after a few years of building, I realized how little work the kit maker did compared to what I was doing. Making the big parts in molds is easy. The builder does all the hard work.

Good observation. I also realized that the Glasair 3 I built was a
"first generation" composite kit, with later labor saving ideas mostly developed by other kit companies. I also bought a Glasair TD kit back in the early 80's and they were even more work, but not by that much. Now I could build another one in a fraction of the time it took me to do the -3. But I've only got so many years left, and starting a project that size again isn't in the cards for me. Now, if I had unlimited money, I'd order AeroSupercharger Solutions $16K bolt on supercharger kit for the Glasair 3 and take out to Reno for a run around the pylons. But I'm spent, so that ain't gonna happen. ![]() Rich On Wed, 12 Aug 2009 21:24:34 -0500, Jim Logajan wrote: The observation may only apply locally.

I did some of the body work myself as I built, and when the parts were
all done, I took it to a body shop. The guy's painting it complete for $4K. And I'm real happy with that. He's done a great job of doing the finish work, and it's ready for paint now. At first, they sanded right through my wing fillets. But I took some of the cloth out there and showed them how thin it was and from then on they did good work. And one nice thing about composites is they repair easily. I started building the 3 in 1991, afterwards the kids came into my life, plus working full time, but I kept at it. But one thing I did find kind of strange is with the parts all out at the paint shop, I've been so used to being able to walk out to my shop and work on the plane, it's strange having no project to work on. I'm sure once it's flying, going out to the airport and tinkering with it will keep me busy. I know what you mean about the mods, I've done some of those too. Most from the advise of other builders I'd talk to at LAL and OSH. The thing is with a Glasair, the final assembly can't be completed until the thing is painted. Unless it's put together complete, then taken to an aircraft painter. And they all charge $12K to paint a composite plane. Good luck finishing your KIS Cruiser.... You know, when I started the Glasair 3, I thought it would take me 5 years to build. Now 18 years later I see I made a big miscalculation!
