[modeleng] Re: are ye all trying to tell me something...

Hi Julian,

You cannot use a Worm drive as they do not allow for overun. i.e As soon as 
you removed power from the motor unless you are stationary, the wheels would 
try to drive the motor and as a Worm will not drive that way, either the 
wheels will lock solid or something will break

Regards
