So you are having a voltage drop issue, in fact it's quite risky to run the RC motor directly from the NXT as you c...

+1 for the personality. Well done Philo!

They have a big round foot suspended between their landing gear that drops down and lifts the crane up, then rotates to move the large crane in a very precise way along the rough rocky/dirt base of a mine or quarry.
