I tried this on another couple of planes in my last upload and since it worked allmost perfectly i decided to build my own planes and hide the mecanism this time. The rod forces the planes to keep in formation flight, but without the rod being fixated. This means that both planes do barrelrolls like two pilots flying next to eachother, and not like one big plane all together. I managed to land this contraption two times now but i admit it tricky. This is for expert level flying. In air no biggie but the landing will be a pain, unless you are really steady on the controls. Enjoy your flight gentlemen. Oh and should anyone have the capabillities to make the rod invisible i would apreiciate it......
