Max III in tough company !

I enclose a drawing with two other FAI 300 kg class contenders.

I do this because I get sometimes critics that i just draw pretty pics that have no understanding of aerodynamics etc. ( btw. I do read quite a lot of those aerodynamics books....by Andy Lennon the last one...foreword by Grumman chief designer ).

Drawings are 98% accurate and definitely in right proportion with each other:

I think the pic reveals that Max III is smaller. Despite being a lot longer VmaxProbe possesses less drag than BD-5B.

The complicated tricycle landing gear and liquid cooled engine needs a lot of room and it shows in profile.
