In late December or early January, a gentleman here asked of there was anyone who would be interested in building a KR for him. If you are still here sir, please contact me at the email address below, I would like to talk with you about your idea. Thank you Peter Johnson mailto:pjohnson@voyageur.ca ---------- ---------------------------------------------------------------------- Subject: T88 for the boat From: "Gaylon Fuller" Date: Sat, 26 Feb 2000 11:11:26 X-Message-Number: 3 Thanks for all the responces I received! I am going to go with T88 as I had first planned on, for the boat. Does any one have any thing to offer on splicing longerons? I have a 13' spruce plank to cut them from and after finding out that the bill from wicks would be about $204 I am thinking about using a splice. I have heard of a volksplane used no piece longer that 6'. I did get on suggestion of tying one end of the board to a tree and the other to my pickup and, we I don't think that one will work!

Do you have to vent thru the bottom for air vent or can you simply drill hole in plastic fuel cap, poxie in a bent vent tube? have put electrical disconnects on wing stubs for tip and landing lights, but how are most of you handling the gas lines? planned on running bent one piece alum fuel line into cockpit from each wing and make connection there. Possibly short section of flexible fuel line on each end inside of cockpit. thanks in advance for the help. fred smith ---------------------------------------------------------------------- Subject: Re: Antenna Locations From: jscott.pilot@juno.com Date: Sat, 26 Feb 2000 15:02:22 -0700 X-Message-Number: 8 On Sat, 26 Feb 2000 17:41:28 CET "Doug Peyton" writes: > Why do we not put all the antennas up on top of the rudder? > > Doug peyton > Tulsa. > Might be kind of tough setting up a good ground plane up there. :o) Many (like me) are using a foinl antenna under the glass in the leading edge of the vertical stab.

If the 12 to 1 scarf splice is cut and glued correctly, when tested to failure the break would never occure at the splice. This is to say a proper splice is always as strong as the original piece. West system epoxy was always used.

I would be sure that the splice is in a straight section of the boat and if you splice all four longerons, splice at different locations to distribute the stress loads. Check with EAA or FAA. There is a manual on wood that is worth its weight in gold and helps to make sure the wood structures are done right.

At present, I have a removable header tank installed in my 2S. I keep leaning toward wing tanks. Mainly for CG reasons. I know if one goes with wing tanks he does not have to deal with the CG change as you would in a header tank as the fuel burns off. Here is my situation. I can not install the tanks in the wing stubs without major modifications again. I have Diehl tri gear and control cables in the way. I am considering fabricating tanks in the outboard wings as close to the inboard end as possible and between the main and aft spar. What ramifications will I experience by doing this? Will the weight of full tanks have any affect on the wing attach fittings?

From: "Mark Langford" Date: Sat, 26 Feb 2000 20:02:17 -0600 X-Message-Number: 15 KRNetHeads, Would anybody like to share how you ran the 5 conductor wire that controls the MAC servo (and indicator) from the horizontal stab to the elevator? I can't help but think that this thing is going to fatigue and break in a fairly short time. I realize that using stranded cable is a step in the right direction, but I don't see a route that's not going to flex it excessively. About all I've been able to come up with it running it into the elevator from the side and twisting it over a long distance rather than bending it over a short distance. Any ideas?

I have one com antenna(vertical stabilizer) and two nav antennas(one in each wing). The transponder antenna is the one that came with the transponder(Terra). The second nav antenna is just a backup for either the com or nav#1. I have tested the com radio using the nav antenna and appeared to work just fine on the ground.

I then ran it up the verticle spar and left a loop in it just behind the aft portion of the elevator spar where it exits the fuselage. I bored a hole through the elevator foam, along the aft of the elevator spar, and had it exit in the square hole where my servo was mounted. I left excess wire in this cavity so if I had to take the servo out for any reason, I wouldn't have to cut the wire. Man, I think I confused myself......................

Will the > weight of full tanks have any affect on the wing attach fittings? I thought the RR plans called for the wing tanks to be in the outboard wings anyway. I could be wrong. It's been a long time since I looked at the manual. But don't worry about the WAFs. Putting the fuel in the outboard wings will actually make life easier on them during flight, since the weight of the fuel will be in the wings and carried by the wings. Landings will be harder on the WAFs though, since that weight will be outboard of them, but it's not something that KRs with wing tanks haven't had to deal with before . I suppose it depends on which type of flying you plan to do more of, aerobatics, or hard landings? At least when your wings fell off you'd be on the ground! And then there's the trim issue, which isn't so bad when you consider that judicial right/left fuel management can take care of that. I'm going to use the extra buttons on my MAC stick grip to send fuel from the left to the right tank as needed. Whenever you notice the thing listing to one side, give it a shot to transfer a little fuel. If I were building another one, I'd have a nice baggage area where that header tank goes. That way when two of you are flying away for a weekend, you'll have a little extra weight up front to compensate for the weight of the passenger. Personally, if I were using a mechanical fuel pump (which rarely fail instantly) I wouldn't worry about the header tank, but would keep a Facet pump inline just in case. Can you run those cables through tunnels, or conduits or something? After looking at your web page, and considering the tri-gear and aileron bellcrank location, I'd say you are definitely hurtin' for space. Maybe a tank behind the seat? Then your CG would move forward as you fly. Mark Lougheed's planning to put a fuel cell back there, but it's a little pricey. There's always those outboard wings...
