After spending a couple hours with Lowell gawking over his 4-1200, and talking shop. THANKS AGAIN BTW, it's not so much about standing height as it is seated height. A 6' guy, 280 lbs will fit, snugly, single pilot but will be cramped dual. I flew with Peteohms in his Model 3 and we were closer after the flight than before....workable, but tight. Width is greater than a 150/152 for the 7. The 7 will be better for a big guy...I'm 6'2" & 225, and will look for the smaller 4-1200 if the price is right....unless I win the lotto, then I'll buy the 7! Hope this helps.
