KR> Folding wings
Belly flap, is not in the true sense, a flap. As I understand it, a flap will give you lift and drag and a belly flap/belly board/speed brake, just gives you drag. It is good to give you a better view of the runway without picking up too much speed. With flaps, you will get both, but from the research I have done, you will not get very much of a lower air speed. If I recall correctly, the most I have heard is 5 MPH and the least is better than 2 MPH. If just putting flaps on the center section stub wing, you may get as much as 3 MPH. Since I have never installed flaps, I can only give you what I have been told by several others who have done it. See N64KR at http://KRBuilder.org - Then click on the pics?

I completely agree with Marks statements. I had another home built that used spring taper pins..fairly quick and easy to remove but still kept the Sonerai 2 at the airport to avoid eventual wear and tear as well as the inevitable rash and mishaps involved in towing not to mention the real possibility of another driver doing something to cause an accident.

KR> Reason For Questions
Hi Neville, There's no perfect aircraft, sadly. I'm in a similar position to you - can't put down a big wad of cash for a kit. I have heard talk of a folding wing mod for the KR but never seen any details. I'd proceed on the basis that the KR needs to live at an airport, not in the garage. KR plans aren't metric, but don't let that stop you. KRs can be built within the limits for RA-Aus registration, biggest challenge will be to get the stall speed (at max weight in the landing configuration) down to 45kts. It's been done (more than once), and as far as I know without straying very far from the plans. If you find a plane that ticks all your boxes, please let me know.

KR> Few Questions
Hi Neville, There are several KR2S variants under construction in Oz. I'm in Qld, but there are some closer to you - e.g. Phil Matheson at Finley NSW. Yes, you can build a KR2S from scratch from the plans, although there are some websites in the KR community that will make the journey a lot easier, for example by helping you avoid mistakes others have learned from. Everything you need can be fabricated by anyone with the right skills and only fairly basic equipment. Sourcing materials in Oz is not quite as easy as in the US, but plenty of people have done it. The wings can be removed, but it depends what you mean by easy. It's not a viable option for taking the plane home after each time you go flying if that's what you're thinking. Best place to start to get a feel for the whole thing is Mark Langford's site and Darren Crompton's site (both are linked from KRNet). Darren was building in Melbourne but sold his project a while back. Not sure where it is now. Hope that helps. Welcome aboard.

KR> Reason For Questions
The folding wing rumor came from a guy several years ago who said he'd solved the problem. He built a mockup and sent it to Ray, who eventually sent it to me. It didn't pass my "reasonable" test for a viable folding wing solution. It was flimsy, and even if beefed up, was essentially a simple system to hang the wings from the stubs in a precarious position that invited disaster...and also made the plane wider to tow. I also completely agree that removing the wings and trailering the plane is something you'll only want to do when you absolutely have to, like after a deadstick landing and you need to carry it home to rebuild your engine! And every time the wings are reinstalled, the wing attach fitting holes suffer a little more wear, and eventually the wings get a little floppy because of it. Perhaps you need to consider something that really does have folding wings, like the Kitfox. But as Dan mentioned, trailering these things around is a pain, or even towing them on their gear, as you probably plan to do. That's how I do it (when I must)remove the tailwheel, replace with a trailer hitch ball receiver, and hit the road. If you really want to build a KR (and most of us do!), you should probably give some thought to sharing a hangar with somebody. A low-wing KR is small and the wings mate nicely with a high-wing plane... Mark Langford ML at N56ML.com website at http://www.N56ML.com
KR> KR2 and RA-AUS certification
Hi Neville, Alan Middleton in Townsville QLD, Australia ( www.BluewaterAirport.com ). I have a KR2 registered in RA AUS (photo attached). I love flying it and can recommend the aircraft type to anyone, although I stress it is a performance aircraft requiring experience to avoid embarrassment, particularly on landing!! The use of the belly flap allows for the slow landing speed required for RA AUS. I have a ballast container up front under the top cowl cover for use when taking a passenger / baggage to ensure COG remains within limits. Ballast can be up to 20kg for my aircraft depending on passenger weight. Powered by 85hp Jabiru motor. Ph: +61407 356 948. Regards, Alan.

Neville, welcome to the forum and Of course you can build a KR from plans only. Many of us have gone that route. I find it a chore to routinely remove the wings from a KR only because you must tow it home after each flight. Not difficult but simply a pain in the neck! When you only have time for an hour or two of flying you must add to that 1-Installing wing bolts, hooking up outboard fuel lines if that option is chosen, hook up ailerons, gap tape, thorough inspection of all...trying not to scratch the paint, find a lost nut in the grass, misplaced tool. This is the easy part! Try removing the wings alone, move them to your trailer, strap them in securely, haul the plane up the ramp and tie it down in the trailer...all the while worried about damage, impending rain, late to pick up a child at schoolad infinitum! Repeat all of this when you get home to your cozy little garage unless you have an enclosed trailer Pat \ -Original Message- From: Neville Sutton Sent: Saturday, November 30, 2013 5:40 PM To: krnet at list.krnet.org Subject: KR> Few Questions New to the forum and have a few simple questions Can the KR-2s be completely scratch built from the plans provided (i.e. no need to buy components) How easy it it to remove the wings on the KR-2s and whats involved Anyone in Australia (preferable Vic)currently building or flying a KR2s Regards Nev ___ Search the KRnet Archives at http://tugantek.com/archmailv2-kr/search.
