hidden passages 15

Not sure i am doing something wrong but can’t get the big autopilot move to work. The timing of the start of the move is determined by the position of the slider that points to winblock but the other slider seems out of sync and B gets trapped there, just before coming to the perimeter railing. Have failed three times using your highlighted block as a target . Have got all the balls in correct place for the finish.
P.S. ive just seen the problem. The two sliders have a different period.
P.P.S. Got past the lowwr part of slider but B flew off next part of this very complex autopilot route .

@ridgerunner P.P.S. ( patience, perseverance, & serenity ).

Well that big autopilot move was very impressive when i got it to work-about five attempts. Liked the hidden passage that B burst into without my intention. Interesting finish.

Knew ya could and thks for the rating.
