You say less than 50 to take it off....does that mean around 500 to land it? lol
Much less but you do have to allow room to fly a landing pattern of some sort and a rollout after touchdown. Remember you don't have brakes. If flown down to minimum speeds in a no wind condition you can get it stopped in less than 50 after touchdown. Not a recommended speed for your first landing approaches though.
