When two pilots get together, one can act as the predator, and the other the prey. One must lead and the other follow. The leader may only use ¾ throttle, and must move smoothly and gently to begin with. The follower may use full throttle, and has to stay as close to the leader for as long as possible. Be sure to know which model is yours, confusion can make for a spectacular crash!
With practice, the flights start higher, go faster, and get closer to the ground. Sometimes there is contact, and both pilots must act quickly to regain control. A great display can be put on with two skilled pilots, one Rocrow and one Rofalcon.
