KR> spar cap width
Help I am missing something. I can't find the width (plan view) for the the spar cap of the outboard forward spar. I have found dimension errors (I think). I am using the New wings as down loaded from Marks site. I don't need any other dimensions If you know the answer please let me know where I can verify. Thank you for the info.

Those spars in plan view are the same as the KR2S plans call for, so look in your RR plans for those numbers. >I have found dimension errors (I think). Oh, really?

Thanks, I of course found 1 15/16" x 1 7/8" x 78" for the outside forward spar caps prior to tapering. I wrote, > >I have found dimension errors (I think). Mark wrote, > Oh, really? What looks like an error in my calculations for spar width is the fact the Center Spar of 2 5/32 plus the two 3/32 faces gives you 2 11/32 width between the WAFs. Now for the Outside forward spar cap. 1 15/16 plus the two 3/32 faces, plus the 1/4" for WAFs gives you a dimension 1/32 wider than the width between the WAFs for the center section. Maybe the bend in the Waf takes up for it? This brings me to another guess. The height of the end of the outside forward spar is equal to the height of the center section spar? I'm going cross eyed trying to figure this out. HELP! Steven Phillabaum Auburn, Alabama "2 mile final for 36"

Outer spars taper to 1" in plan view and 11/16 in side view (front view) For what it is worth, I think that is crazy - reduces attachment area for wing surfaces (skins). Mine will taper in front view only - constant 1-15/16 thickness in plan view for max glue area. Need the rear spars? Ed Yahoo! Messenger - Communicate instantly..."Ping" your friends today!

If I had it to do over again I would make my spar caps thicker at the root on the outer wings and the center all the way across. this would allow for plenty of meat and make locating the wing attach fitting easier.

Hi Ghris It's nice to hear voice of other KR-1 builder. I have been lonely wulf for years so my modification might be different than their are generally. I use RAF-48 in rooth wing and GAW-2 in outboard wing. There is one feet long area on the outboard wing where airfoil will change from RAF-48 to GAW-2 The reason why I am doing it this way is that I started built orginal KR-1 with short wings.Few years later I regonized that I don't have money to fly private lisence but there was chance make it to ultralight gategory so I desided to do wings according Ken Rand KR-1B plans. If I could start my project again, I will do one piece wing with gaw-2 airfoil, naturally with tapered shape. Orgonal attach fitting steel weight is around 10 lbs but one piece wing can be attached to fuselage with four bolts. How far you are with your KR? How you have attached your shouder seatbelts and what kind of landing gear you are going to use?

Thanks Edward. Stupid question... Is the height of the root end of the outside spar the same as the height of the center spar? From what I can tell it is.

The only stupid question is the one you have, but don't ask. No - they are not the same - the centre section cap is 2" deep and the outer is 1-7/8" (not sure how this will look in print - it is 1/8" less than 2"). Cheers Ed Yahoo!

I think he is asking if the outer spars total thickness at the root is the same as the center spar total thickness. And he's right the print does not say if I remember right. If you are building the new airfoil (AS5048) the thickness of the center spar is 8.19 and the root of the outer spar is the same. Was that what you were asking? Chris Theroux Gilbert, AZ

YES, Thank you. The net can answer questions.

Good morning. I looked in the KR Archive and did not find my answer. Is the Spar caps the same width on the new wing (AS5048/5) as the wing with the plans? Should I change my spruce order other than the basic order for the KR2S? Steven Phillabaum Auburn, AL.

Should I change my spruce order other than the basic order for the KR2S?< Spar caps are made from the same wood. If anything, you might need a little more of the spacer material between the caps, but I doubt it, and if you need it, it won't be much and you can get it in two days from Wicks in a very small box. One difference in the AS5048/15 (or whatever we want to call it) is that those pieces have to be tapered, unlike the plans version. This optimizes the wing strength to weight ratio, but makes construction a little more difficult, because those vertical members are going to want to keep sliding around while they cure. You'll need to screw a block down to the table (or figure some other way) to keep them from sliding around before the T-88 cures. One other thing is that if you're planning on using the Diehl gear, go ahead and put some solid spruce stringers in between the caps at the point where the gear attach fitting goes, but I think that's mentioned in the instructions at http://www.krnet.org/as504x/as5046inst.html .
