KR> Carbon Fibre
Tim first of all you must decide the overall mission of your aircraft. Super fast, or what seems to be the norm with others on the = list. First be advised that CF blocks all radio, GPS signals. That said, if = you wish a clean exterior, low drag machine use carbon fiber sparingly. The forward boat ahead of the wing as well as cowl, wheel fairings and pants come to mind. If you're not that worried about total performance the go ahead and use carbon fiber BUT you best have a wad of cash, this stuff = isn't cheap. Myself, I would use CF for the seat pan and especially the seat = back and bulkhead at the rear of the baggage shelf. Why? Exactly those = properties that make CF undesirable for internal radio antennas. Passive radiation = from said antenna are not exactly a boon to ones health. Want an example? Lay your hand on the antenna and push the transmit button. Next day your = hand will look like a football it will be so swollen. (watch the flame wars = start over that statement) Much has been written regarding the use of Kevlar and its' difficulty to work with. However Kevlar's strength is not much lower = than CF while it has excellent properties such as vibration reduction, superior strength, lower weight (than traditional e-glass) and excellent damage resistance. For my own KR I went with the composite boat method of construction. This does away with the outer plywood skin and replaces it with foam between all the boat formers and sandwiched both sides with = fabric (be it glass, Kevlar or carbon fiber). The inner skin on mine will be of Kevlar since the overall finish is hidden away. The outer covering is S-Glass which is 30% stronger, 15 % stiffer and retains those properties = up to 1500 degrees. S-Glass is finished the same way as traditional E-Glass = so you can achieve a truly outstanding outer finish on the aircraft. Hope = this helps with the carbon fiber issue. As to engines, well many have responded already but I don't know what a Jabaru sells for in Australia so I don't feel comfortable = commenting on the issue other than the lighter weight of the Jab may necessitate = using a longer engine mount to keep the CG with range.

KR> Carbon Fibre
Overall performance remark was directed towards all the different antenna that would have to hang out in the wind producing drag. Remember that with the KR we operate at the lower end of the power scale due to design constraints. The Corvair, VW and Continental 0200 only produce = around 100hp so every little detail is important to get the most performance = from your little bird. The outer wing panels would be an excellent place for = CF although I personally prefer Kevlar for the leading edge, but then again that's my preference only. Nav antenna must be located at 90 degrees to = your flight path if using the copper tape method for internal antenna. The logical place for this would be the stub wings IF the builder is not = using aluminum tanks in that area. Keep in mind that all antenna are affected = by metal structures anywhere close to them so watch for electrical wires, control cables and other materials that can block the radio signals. As for the buckling properties of carbon vs. e-glass. I suggest you read a book called Composite Construction for Homebuilt Aircraft by Jack Lambie. A wealth of information in that little gem. There are several = other books out there and I'm sure other on the KRNet will be happy to = recommend them. First and foremost the strength of fabric, be it carbon, Kevlar or glass is in tension, not compression. That is the reason we have substructures such as the foam. When the core material is layered = between the chosen fabric it is only then that compression strength comes into = play. The thicker the core material the stronger the structure (to a point) I could go on but there are many on this list smarter than I so the best advice I can give is read the book since it will answer many of your questions and may even give you a few ideas of your own.

Obviously I'm missing something here John. Kindly explain the difference between a properly baffled fuel tank in the stub wings versus the same = tank in the outer wing panels.

Now there's a true statement. I have spent the better part of a year downloading material from the archives as well as various builders' = sites and incorporated all the different methods of construction as well as changes into my own construction manual. Everything printed out and = inserted into the Rand manual in the corresponding section as well as added a few sections that didn't exist before.

RE: Réf. : RE: KR> buying KR plans
Kevin first off I agree with the dated plans statement. Any one in their right mind that has taken any time at all to check out the massive amounts of material posted in the archives as well as the various builders pages knows beyond a shadow of a doubt that the KR is alive and well in name only. Now before the rest of you animals get your knickers in a knot think before you write or flame. How many birds currently flying or under construction are strictly plans built to Ken's specifications? To my mind, very few as most have incorporated many of the flight safety and comfort features pioneered by those on this list. Granted there are a few out there but they seem to be damn few and even they wouldn't pass Ken's muster as these birds have higher horsepower engines, radios, starters, navigation equipment on board. Nothing wrong with that as they are safer birds. Safer in that being able to radio in when you have a problem or knowing exactly where you are makes one a safer pilot. I never had the pleasure of meeting Ken but you only have to look at the accident report of his demise to realize that his bird versus the ones of today are totally different animals. Does this mean that one needn't buy the plans from Rand? Hell no but if you buy a partially built project and the plans aren't with it and you cannot get any acknowledgement from Jeanette regarding the transfer or purchase of new plan set that does not mean you're out of luck. Far from it, just build it and go flying. Business is business and if people don't understand that, though, get over it. I was lucky enough to get a full plan set with my project and the serial number has never been used so I'm ok on that note. However there have been so many changes to the bird that it is a KR in name only now. Longer, wider, Corvair power, flaps, speed brakes, new wing design, well you get the picture. Insurance is a whole new ballgame and I haven't got that far so I leave that to those that have already run the gauntlet to answer. Doug Rupert There is one part I held back mentioning in the first email as I really am not sure how it all works. I am talking about Insurance. I would think insuring an airplane called a KR would be easier than insuring an airplane built from KR plans, but called something else. It would seem it would be like insuring a prototype airplane. Also, I must ask. Do people actually buy the kits RR sells? I know this sounds like RR bashing, but the plans are terribly dated. What has kept the design alive is people like Langford, Jones, Wynne, and others. We all owe so much to these guys who seem to go to great lengths to share. I want to thank them for continuous improvement on a simple, efficient design. Now we need to one-up them for future builders. ;-) Kevin. -- No virus found in this outgoing message.

Ed I don't believe anyone is saying that it can't be done, FAA exempted (depending on the inspector). I've heard a lot of why's but this is however an experimental class of aircraft so anything is possible in theory. A complete redesign would be in order though since the wings would have to be longer and this would require a stronger spar. The AS5048 airfoil would solve the spar issue BUT that airfoil was designed to extract the utmost performance from the KR so who knows until it's completed and test flights begin whether or not it would fall within the FAA parameters (depending of course you could find a friendly examiner with an open mind) You'd probably have to use a smaller engine than those being currently used by most KR builder and drivers. Could be one hell of an expensive experiment when finished. Good luck Doug Rupert -- No virus found in this outgoing message. Checked by AVG Free Edition.

KR> VW Getting more Power
Dan more power is always available no matter what the engine but at what cost? They currently have a highly modified VW that puts out a shade over 1000 (that's right a thousand) horse but you sure wouldn't find me flying behind that grenade. One of the main reasons I chose to go Corvair is the fact that 180 HP is not unreasonable since GM didn't change a thing on the block or crank itself for their turbo models. Of course this was on a road vehicle and does not apply to aircraft applications. I'm following WW's turbo experimentation very closely as this along with modern fuel injection would seem in my opinion at least to be the way to go for excellent torque and fuel efficiency. Modern electronics has allowed these systems to be self adjusting to 10,000 feet doing away with complicated mixture control. Of course all these improvements are highly dependent on a reliable electrical system but as so many KR builders have proven over the years, anything is possible given enough determination, money and staying power. As I was scrapping out an old Dodge Caravan the other day the throttle body fuel injection manifold caught my eye. The letters 3.0 liter as well as the fact that it is compact and completely made from aluminum started the wheels turning. Needless to say the complete unit, sensors and wiring harness were carefully removed before the carcass left for the scrap yard. Maybe one day but for now it's getting a stock Corvair built and mounted for flight. Doug Rupert Yes, is have seen this done. There is VW repair and machine shop, or was, in Donalds, South Carolina. The owner, Pat, made a 1/2 VW into a 2 liter engine I am sure that Jerry has more of the specifics on this, but I have seen it done. However, I don't think that I would fly behind it. Daniel R.

KR> GPS
Frank I bought an old Lowrance Worldmap 1000 from a boat for 80 dollars. Lowrance doesn't make them anymore since they figured out that if they change the name to Airmap 1000 they can sell it for a bundle more than a boat owner will shell out. Way cool moving map and huge screen so a magnifying glass isn't needed to see what's on the screen. Not color but the money saved can be better used on radios the way I figure. A quick check of the local boatyards or e-bay under marine section yields a load of treasures that are easily adapted to aircraft usage. Actually been looking at the GPS steering servo from the boat to be used as a simple autopilot. If that servo is strong enough to steer a 40 foot yacht I'm sure it won't have a problem pointing a KR in the right direction. Doug Rupert Speaking of GPS, I saw a GPS unit that plugs into your computer for about $80 (US) the other day. Looks good for those who are using lap-tops in-flight. Frank
