Larry: I am all for caution on this one! The Zenair 701 & 801 have full span fixed L.E. Slats which according to their Aero Enginee tends to give them a huge pich control issue to deal with. The book on the 701 gives a T.O. run of 90 to 125 ft or so at any rate is short which is why the turtle deck is Horiz. & the tail ground clearance is high when parked. Per Caleb on of Zenair's Aero Es.)
