Bill, based on my experience building kits, and I've built alot of them, I would have to say the big three, Great Planes, Top Flite and Sig, in that order. The die cutting in very important, it needs to be done with sharp blades and a manufacturer that cheaps out on the blades will not produce a good kit. Dull blades will crush the balsa.Β*The plans and instructions from these three manufacturers are very good as well.Β*Laser cuts kits are also veryΒ*nice but you need to remember to sand the burn off the edges alittle for the glue to stick well.
My favorite kits are Great Planes kits.
My second kit build and second flying planeΒ*was a Great PlanesΒ*Ultra Sport 60. I'm actually building my second US 60 now and the kit is just as nice as the first one. It scared the heck out of me when I first flew it but by the 3rd or 4th flight I was comfortable with it and it was my favorite plane for a long time. It is a bit of a challange but you can do it.
Remember, no matter what plane you build, ''Build light, build right, great flight''. What I mean is trust the manufacturer, don't try toΒ*build a crash proof plane, it can't be done. Avoid adding extra weight, a lighter plane will fly better. Make sure to build it straight, pay close attention to alignment. Take your time.Β*
