The rules I am outlining for myself for this different no electric motors, no batteries, 100% Lego, and No Pneumatics. I am doing this because of the cheap price of Pull-Back Motors on BL, so I thought It would be worth a try!
My first idea was basically to use a singe pull back and go motor and the large motorcycle wheels. It would look something like this:
But It was not fast enough ( :
So I have the Idea to actually add more Pull-Back motors. Using 4 of the newest ones I am hoping to get an increased speed using this method I have 3 more of these motors on order and am eagerly awaiting their arrival.
I want to see if anyone else on this forum might have another idea I am willing to hear their ideas.
