K9 project


hi there and a big hello to all 

this is my first post on here and thought i would show all what i have done (see pics)

so far i am very happy with my project but i am having trouble with the drive system

what i have tryed so far is

windscreen motor drilled hole in top added a 5k pot to it 

taken apart a servo removed the motor from it 

im using a daul Hbridge to run the motor and have put the servo motor outputs to the hbridge

servo is connected to my rc recever

ignoblegnome attempted something similar. He was set straight by someone with a better understanding of how it all works. Just search for "ignoblegnome servo". Sooner or later you will find the link you need to the information.
