My 4* will take off in less than 50 ft and if the wind is blowing you can land it where you want it. My Twist , 10 ft on take off and go vertical, you can darn near land it like a heli.
Alot depends on the plane , as to how much runway you need. If you fly jets , it better be a long one. lol. At our feild The runway is a 100ft long and goes up hill on one end. Our whole feild is 250ft x 250ft with corn planted on all four sides. Kinda like landing on an aircraft carrier but it not moving up and down.
