Four in formation would be great. We did two. Warmed my heart to see that.
FYI- I had a saito 120 in mine. Would knife edge from one end of the field to the other with no problem. Lost it when the battery came unpluged. It came lose from its mount under the tank, then unpluged itself after a roll. Mine wasnt secured because I just cycled it. Famous last words, I'll take care of it after this flight. Never do that again.
