Eric, the Cubs use a USA35BMod airfoil.
The Cherokees use a 65sub2-415 airfoil.
No similarity, though the Cherokees have a more docile stall.
nmflyguy, I've flown the AMRD 150 hp PA28-140 testbed in the Denver-Oshkosh Air Race. Standing start out of JeffCo, flying finish at 500 AGL at Appleton. We did 903 statute miles straightline non-stop in 7 hours 5 minutes, landing with an hour of fuel remaining in the stock 50 gallon tanks. We were going for endurance, not speed. Averaged 130 mph against an average 3 kt headwind. That average speed included the climb from JeffCo up to our cruising altitude of 14,600 feet. We crossed the finish line at 500 feet AGL and 180 mph. Average fuel burn was 6 gph.
Even though Art reflexed his ailerons and flaps up 2°, the plane also has exceptionally good STOL performance, but not a lot of brush clearance at the wingtips. Stall is docile. Contrary to one of the posts here, the Cherokees have considerable washout.
