As a much younger person I used to have a Vemco Drafting machine and design my own planes and then build them, that was U-Control and Free Flight. Today I just see a plane I like and find a set of plans, buy them and do some simple redesigning. Back in those days you had to build or not fly and all the hobby shops were stocked with boxes and boxes of kits!! You walked into a shop and it even smelt like balsa wood. Today we have the ARFs and they have gotten a lot better over the years. An ARF will never last as long as a good made it yourself plane, they aren't designed to last, they have no wood in them and are built too light. Still, you will be in the air and having fun, that's a pretty good thing and in the smaller sizes they are a lot cheaper then a kit build. If the OP loves his little Kaos ARF then the next step if you want another one is getting a good kit, Mr. Bridi's son is still making the Brid kits and the 60 size Kaos is top of the line. If you build one and don't crash it too hard it will be with you for decades, mine just got it's forth repair and cover job. If you want something different but fly's the same then the GP Ultra Sport is te son of Kaos. I have the plans and am getting close to the finishing on a Daddy Rabbit, pre dates the Kaos by a few years, this is a plans built only plane though, no kit. Kits are stronger then ARFs but a lot more work and not for everyone!! I'm one of those people that doesn't have an ARF, I have had one or two but I like the pride I get from building my own and the ego thing of having something no one else has. Most people don't even know what most of my planes are!! I get a lot of that, Who Build That questions. I get a kick out of that too.
