Well I won but I'm pretty sure that I didn't win as intended. You didn't say tricks were or were not required and it appeared that B was stuck without tricks. I used a SBS to get B out then an auto pilot to get on the rotor and then a SSS to fall down with the win. I didn't use headless R.
I also won without any tricks but headless R is not very stable by the time you get R out and his randomness is annoying.
I let the mill push both B and headless R but I could not reach the win. Actually, I do not even see the win but I assume that it must be in a hole.
