The cabin width on my stock plans-built KR-2 is 34 inches inside rail to inside rail. Two 200-pound friendly persons can sit in the cockpit and shut the canopy with both heads against the Plexiglas; actually flying the aircraft is actually possible, but highly unlikely. At 5' 10", leg room is fine. Four flights with one 200-pound person have been done. I am strongly considering converting my KR-2 to a single place machine with one center seat. Will finish the Phase I testing and re-visit the conversion consideration at that time.
Sid Wood Tri-gear KR-2 N6242 Mechanicsville, MD, USA ------------------------------------------------------------------------------------------ While I?m only 5?9? i have wide shoulders. I widened my fuselage to 43? at the outer edge of the upper longerons. Like a glove. I?m crafting everything i can.( some are a learn as you go). I want to buy as little as possible. So modifying is not an issue for me. ------------------------------ ....I'm a 185 pounder and 5'10" high and I fit (with a "cloned " passenger )resonable comfortable in my 40" wide Kr! When I widened my fuselage ,I put back the 40" to the shoulder area.Therefore I had to put back the straight line of the longerons a little ( 10-12 inch). Therby,making the turtle deck was a bit tricky,because it had to be spherical in this area.(due to the slightly curved longerons). Of course the Kr2s is a comfortable single seater also with plenty of storage. I would not recommend to build a "Kr 1 s" because then you will lose the mentioned advantages of a two seater. And finaly ,to build a single seat "Kr1s" with an emty weight of about 400 to 450 pounds is almost impossible. Herbert German Kr2s
