I get claustrophobic and on long flights personal hygiene can make for unexpected ejection seat deployment (just joking). Too damn many hours stuffed into a shoebox military aircraft so jammed with weapons and electronic systems you couldn't move if you had to. Nice to be able to move around a little to give the hemi's a break. May not be a problem for you young guys but anyone who has spent the better part of his life perched on an armor plated seat will testify to this truism. Ran the figures thru Airplane PDQ and seems damn rear impossible to load outside CG limits if one uses some common sense and plays with forward seat position and slight addition to the firewall position. Those with heavier water cooled engines and wing tanks only are in a better situation as most loading is right over CG or damn close to it, Also suggest moving the tail wheel forward slightly to reduce the moment arm helps greatly.

The smaller cell structure should actually be an advantage as it will take less micro to fill the cells therefore your finished weight will be reduced. The smaller cell structure is also an advantage over the larger variety in the sanding department as well, there is a much lesser chance of teasing pieces out during the sanding process, leading to the addition of yet more micro to smooth the surface. As to why the micro isn't taking to the surface of the foam is a bit of a mystery. I'll see what I can find out. Cheers.

If you can, see about getting Polyurethane foam. Baring that, you might want to consider making (having made) aluminum fuel tank(s).

I am using the same foam in my project. If the foam damage is beyond using epoxy filler; buy some two part foam from ACS or Wicks. Mix and apply liquid foam to repair the surface. If you haven't used this stuff before experiment with a few test pours to get a feel for how is behaves. Note: the longer you mix the foam the more dense the results. Timing is a factor. Chilling the chemicals[i.e. refrigerate] helps control the density also. After the foam cures; cut and sand the surface.

While polyurethane foams can be cut with a hot wire, it would be inadvisable to do so without very good ventilation and breathing apparatus as they do release copious amounts of poisonous fumes. One thing to watch out for is just how fast that 2 part expanding foam takes off, a little goes a looooong way. If you really want a good laugh, mix 200ml (8Oz) of each in an ice cream bucket and put it on the floor of an old car (with windows intact) and shut the door.... Cheers.

I am afraid about delaminating +++++++++++++++++++++++++++ Hello Alex You are getting a good response to your question. Some of the information will conflict as each person gives you what they believe is best. I suspect that you may be more confused after this then you were before. I have been using these products for 20 years (30 years for Styroam /polystyrene) My contribution The negative side of blue foam is: a) Fuel will dissolve stryrofoam. b) Blue foam releases harmful gases when it burns. There are solutions to both of the above. Other than the above I firmly believe that blue styrofom is as good as polyU in every respect (or better) provided that you understand it and use it to its best advantage. Most KR's are built with a "single sided sandwich" using relatively thick chunks of polyU foam. Full attention is given to the outer surface and little attention is given to the inner surface. Have a look at: http://home.hiwaay.net/%7Elangford/swings.html The builder makes every effort to remove unwanted (surplus) foam from the inner surface and then provides a glass skin on the inside - thus a true sandwich construction. This builder uses PolyU (no problem in the USA) but you can do the same with your blue foam and achieve the same results with a THINNER core material if necessary. I suspect that Mark L is using material of about 1kg per cubic foot, but you can use blue foam of double that weight (4lb /cub ft) but cut it to half as thick - and still be smiling. You can also cut your foam with a hot wire (I regularly do) provided that you take every precaution NOT TO BREATH THE SMOKE. There is a particularly good KR web site where the builder used hotwired blue foam wing sections (with weight reducing cut-outs) for the wings. I tried to find this reference for your benefit, but I cannot remember where I saw it - maybe one of the netters will know and tell us. In the meantime - have a look at http://www.whisperaircraft.com/ website. I think I am correct in saying that all of the work was done with Styrofoam. Dene Collet (Port Elizabeth SA) is familiar with this project and may have better information.

Should I notch that cross member or sand the longerons level like you do for the bottoms? Thanks for any advice.

Subject: RE: KR> boat question To: "KRnet" Message-ID: Content-Type: text/plain; charset="iso-8859-1" Jim, My thought is you will want all the strength in the longeron that is available. So don't sand anymore than absolutely necessary, especially at the fire wall area. Some builders, I have observed on their websites, have added extra plywood on the inside top and bottom of the fuselage sides to beef up the firewall attachment. These builders are using the bigger engines for increased performance. I am using a 2180 VW and have 3-inch wide 1/4-inch plywood at the top and 2-inch wide 1/4-inch plywood at the bottom. The floor from the firewall to the main spar is 1/4-inch plywood inside for added strength (and for big feet per the KR-2 plans suggestion). All these added plywood pieces are gusseted into the firewall frame. Perhaps this is overdone, but I want to avoid a citation from the EPA for littering the landscape with old KR-2 bits and pieces. Environmental cleanups are getting so expensive these days...

I inherited a 95% complete KR-2 from a deceased member of our EAA chapter. The aircraft already had an airworthiness inspection; it was taxied but not flown prior to his demise. The problem is that it is substantially over weight (in excess of 700# empty); unfortunately, I had to add 22# lead to get the CG inside the aft limit (making it a lead sled in more ways than one.) At a full fuel weight (limited to one occupant) of around 1050#, I was wondering if the KR-2 is up to the task structurally. Any additional info would be greatly appreciated. ------------------------------ Message: 20 Date: Wed, 16 Jun 2004 16:43:58 -0400 (Eastern Standard Time) From: "Dan Heath" Subject: KR> foam at the end of the stub wings is pretty "boogered up" To: "krnet@mylist.net" Message-ID: <40D0B10E.000001.03540@COMPUTER> Content-Type: Text/Plain; charset="iso-8859-1" If I were fixing this kind of problem, I would sand the good area around the offending area, very good, so there was a slight indention in the good area. Then I would cut out the offending area with a saw. I would then glue in a good piece of foam with hot glue. I never use the mixable foam as I understand that it does not quit expanding for a very long time and when the heat hits it, it starts expanding all over again. Now, just sand to shape and cover as you would normally, overlapping the good area you sanded down. A little super fil, primer, and paint and you will never know that it had been "boogered up".

I find about 5 minutes with a heat gun works. I would recommend a layer of glass after finishing the foam.

I have been working on my Kr of an on for 20 years It is good to work with your hands if you have a high pressure job. Your Kr will never get jealous. You can hang it from the ceiling when you do not have time for it and it will give you great insight into the the woman that come into your life. ------------------------------ Message: 23 Date: Wed, 16 Jun 2004 22:00:25 -0500 From: larry flesner Subject: Re: KR> boat question To: KRnet Message-ID: <3.0.6.32.20040616220025.007bc330@pop.midwest.net> Content-Type: text/plain; charset="us-ascii" >I am installing the top cross members on the boat.

I added several additional glue blocks in that area to help with the 0-200 I'm using.
