Thanks, Kenny Kenny I think you will find that this will depend on what carb you use. If you use an Ellison I would say yes to both questions. A fine filter as well as a boost pump for take off (max power). But with something like a Revflow or a carb from GPASC I would say no to the fuel pump and yes to the extra filter during the first 100 hours. It seems that no matter how clean you try to keep your fiberglass tank during construction it always ends up with a bunch of junk in it. I would install a simple Fram type inline filter (that you can see through) that is easy to change. Keep and eye on it the first 100 hours. -- zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Micheal Mims Sanding and Filling AGAIN! :o( http://www.fortunecity.com/marina/anchor/270/ mirror @ http://www.geocities.com/CapeCanaveral/Hangar/4136/ http://members.home.com/mikemims/ Aliso Viejo CA ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ---------------------------------------------------------------------- Subject: Re: Subaru motor From: Warron Gray Date: Sat, 22 Jan 2000 16:13:44 -0500 X-Message-Number: 5 The SVX is a 6 cylinder boxer puts out 230 + hp in stock form but it is huge and heavy.

From: KR2616TJ@aol.com Date: Sun, 23 Jan 2000 12:13:07 EST X-Message-Number: 6 As most of you know, last year I got "almost flying" syndrome and totally stripped off the foam on my wings and removed and replaced my aft spar. I had everything coupled, plumbed and wired. I do now again. The reason for this was to take advantage of the improved flying qualities associated with removing some of the incidence in the wing. I moved my aft spar up approximate 3/4". My thinking at the time was why finish something if all I would be doing was wishing that I had done it differently. Well, at about this same time there was a tremendous amount of research being done using stability analysis on the KR with relation to the horizontal stab. To make a long story short, my tail is the outcome of that research. Trust me, we didn't just say "here's an airfoil and we'll just make the whole thing bigger". I'd dare say that more research went into this tail than the research on the original design of the KR itself. With that said, don't go trying to duplicate what I have done just by the pictures. There is more to it than just "looks". Let me fly the thing first before you go putting one on your airplane. I really don't want to get into the particulars just yet but suffice to say, I have no problem in accepting the mathematical calculations involved in the analysis. The best thing about this design is that is uses the existing KR measurements at the attachment points, so you can use a plans built fuselage and put this tail on it. Remember, let me fly the thing first. CAD is wonderful:-) I've updated my links page and added a new page called "Tail". Go there to see the update. Some of the pictures are large but I wanted to get good detail. I hope the download wait is worth it.

In regard to Alum. Tanks, best solution, have it welded. Second, an Alum. Patch made of the same material, held in place with a tight pattern of real Cherry brand blind pop rivets sealed with real aircraft PRC (as any RV builder). Do not fool with other solutions in tanks, especially in the fuselage. A cup of gas in the plane with you being blown around will incapacitate you quickly. thanks William ---------------------------------------------------------------------- Subject: Re: wing attach fittings From: T152GMAN@aol.com Date: Sun, 23 Jan 2000 20:19:33 EST X-Message-Number: 14 what is inconel 718 ---------------------------------------------------------------------- Subject: Re: Cooling From: Bobby Muse Date: Sun, 23 Jan 2000 20:51:09 -0600 X-Message-Number: 15 At 08:22 AM 01/21/2000 -0800, you wrote: >> Speaking of air flow, make sure you run an air hose >> to your gasculator(sp). >> Very important. >> > >Also a tube or two to cool the mags is a good idea. > >I saw a KR2 one time that had a oil cooler mounted to >the firewall and he had built a fiberglass duct that >had a 2 inch scat hose connected to it.

I am just getting around to reading your attached email and I'd like to say the NO, you did not "run off at the mouth". You touched on two very important points which cannot be stressed enough when using epoxy on wood; One, ALWAYS preglue a joint, especially end grain which may actually require 3 or more coats before joining, and Two, NEVER over clamp components! I see alot of people using spring clamps on epoxy joints and this is a big NO-NO. Epoxy must remain in the joint for it to do any good and any kind of clamp which applies contiunuous pressure will continuously squeeze the resin out, even if the joint has been preglued. In my opinion it would be good to see more comments like yours here in the list as new builders, (and some 'oldtime builders') need to know information like this. Remember, "Common Sense Is Only Applied Knowledge." I'll give you an example, over the 20+years I've been building I have come up with a method of finish sanding an epoxy/cloth finish which is simple, easy, fast, and ensures almost no risk of oversanding, and will lead to a very 'flat' - ie. smooth - finish, yet I've never seen reference to it on this list or others, including boatbuilding lists. I'm curious about what others are dong to ensure 'flat' finish surfaces and would like to hear from those who have completed their finish sanding to swap methods. mailto:pjohnson@voyageur.ca ---------- > From: Rick Hubka > To: KR-net users group > Subject: [kr-net] Re: T88 glue > Date: January 11, 2000 2:23 PM > > There are several KR builders here in Calgary Alberta Canada(including me) > who have used T-88.
