Formation flying

I have been wanting to try flying in formation with my father. Tonite we tried it for the first time. It went pretty good. I was flying my GWS T6, and my father was flying his speed stick, it's like a slow stick except different wing and tale feathers, they are leftovers from a wing dragon. Anyhow it went well for our first time, we will keep practicing and eventually i will post photos or video of our efforts. This realy gets me thinking about the sonic battle modules, i have seen a video of sonic combat once and it looked like a ton of fun, thing is I do not know where to look to find them, i'll keep looking.

P.S. It's time for a GUESS WHAT..so GUESS WHAT! guess what aircraft this is at the top of this post...
