if there is two motors it is a differrential mechanism. and w=w1*wm1+w2*wm2 w=wheels velocity of angel w1=velocity when the other motor stops w2=velocity when the other motor stops wm1=1st motor's velocity wm2=2nd motor's velocity s=w*l*t Q=S/r Q=angle (rad) l=length

Can you give me the formula for taking off a helicopter? This formula must give the minimum force that produced by moth for taking off. :rolleyes: (i want to project a miniatur helicopter).Thanks... from eng. student
