RE: wingspan?
My brother has a Skyfly 2, which is quite smaller than the MAX, and it needed a rather large area. I'd say, four football fields grouped together. However, he was learning and needed the space to give himself time to set up for landing approach. If you are a little more experienced than a newcomer, than you may have enough room to fly it in a single football field. I might add, that the Skyfly 2 is pretty quick for a small electric 3 channel plane. I believe it has a Brushed 380 pusher motor.
