I found an online airshow and teams are the theme of the show.

Here's a link which contains the details. If you are interested in performing at this airshow then we could practice a routine that is very similar to the two horsemen act that is flown at airshow today. These maneuvers can be flown just as well with four planes as with two. Let me know if we are going to fly before Dec. 31 because that is the signup date.
