how to calculate peak torque required to move the vehicle. i tought that tracks would give me better grip than wheels and this way slip less ? thats what i'm afraid of, thats why i started this thread. i dont want to buy the motors and find out that they cant move my vehicle. and i need a way to calculate this no mather what type of motors will i use. but the webpage that was posted here seems to do some calculation, and if i assume they are correct this motors should do.
