Re: To Joe [TANKS]

Thanks Frank,

So full skid turning equals a pivot steer and adding proportional turning would make 
it the same as a real tank.  Cool.  Thanks for the help.

Also, your work on the new controller is quite impressive and will certainly make it 
easier to get into the hobby.  That and some of those new motors with the  gear 
boxes will really simplify construction and should most certainly increase the 
number of tankers in the hobby.

Keep up the good work, this is a great hobby.
