The KR as such is nothing much, but the concept generally results in a stunning wee bird - it offers wonderful potential and brings out the best in the "experimental" component amongst us. Witness N19MMR, N41768, N891JF, N4DD, N902G, N1213W, N??TP. The jury is still out on 53ML, but my guess is

Steve you have to think about what you just wrote there. Not much difference between foam and ply except for density and weight. If the skin is properly laid up per manufacturers spec the resulting structure will be the same. Mahogany ply is widely available around the world and has been used

Flaperons on a short coupled, low wing aeroplane with very little dihedral is definitely NOT a good idea. Why? Not me that wants to do this so not my function to defend the crazy notion - give me your logic and I will reply. Eddie

Duncan The undercarriage height is influenced by a few things, but the two issues in this case: The Original KR1 and 2 had a low tech, low cost, very simple retract system that was almost great. Many KR's are still flying with these folding legs(taildragger). The simplicity of the design

KR> Speed Brake

mounting it from the front spar is fine, but mounting it from the rear spar has the added benefit of pitching the nose down a little to give you better visibility. > Mounting the speed brake further fwd has advantages: = more space for a longer brake. = wee bit more height on a tail dragger

KR> spar cap width

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

Thanks Ron - the pics came out great. What version of autocad are you using? - I may have what you are looking for. (Remember that they use ply on the plans, not foam /glass). I doubt that the weight of decent folding legs are worth the hassle on a small bird - word is that a clean bird with
