2 Balls and 4 Rs

Choice of zbot or R and I initially picked the wrong one and wasted a lot of time before i realised i had made the wrong choice and despite having two bots up top I couldn't win. Switched bots and made quick progress. I used a slightly different way to get B onto the draggable near the end but otherwise same as video. An enjoyable challenge.

@ridgerunner - Yes - getting the Rs in the right order is important but only the 1st one can't be swapped out. Thanks

A very good level. But I made a serious mistake by focusing on using only two autopilots, and my B died at the end trying to divert the Z/R stack. By the time I realized it, it was too late. But since the level was quite complex, I was satisfied. Thanks @gmacpro
