Actually there is one in between that.

1st we did one plane two different radios then just a few weeks ago Mike Caglia and I borrowed a 40% plane and he flew rudder and throttle while I had elev and ail. That was a blast rolling circles and the whole bit. Natural evolution was the 2 planes one tx which I will say again is by no means perfected yet. Not sure what is next I am out of ideas. lol
