KR> KR1/KR100?????whats the difference?

[Global Solutions]

Good day list this is my first post to the group.

I ordered the plans for the KR1 and after reading the list I learned of 
the KR-100. Both are one person airplanes but the 100 seems to have 
better specs as far as speed goes.
What I have to work with is a 85 hp Corvair engine or a VW bus engine 
18xx cc.
Can anyone here shed some light on to the pros or cons of the KR1 VS the 
KR 100 and what changed from the KR1 to the KR 100? Does anyone have the 
plans for the KR 100
Thanks for your help
Regards
Stan
