    I have a motor that had the battery/switch separate but my dog chewed that part and i threw it away. i have the motor and its housing, and about 3 feet of wire still attached. Would this still work for me? Its a motor from the Knex Sawblade Thrillride set.

    niftifty but it would be even grater if it could turn. try two receivers and two remotes duct taped together or taken apart and made together. and two motors on each side.

    If you look closely you can see more wires that were linked to a second motor for stearing. I didint want to take the time to use it, but will in the future.

    COOL!!! I will look into it. I think i had one of those but the controller broke. I still use the main unit though.

    You did I will post when I get mine fixed if I can remember where I put It and how to put it back together although it should be really easy.

    yeah that would work I didn't know your remote was capable of steering cool you should do it someday.

    there used to be these red remote control motors that you can use which is easier than this and it can turn and stuff.

    I the stuff to make it turn, but I wanted a simple forward backward design. In the future I will make one that turns. I wanted to make a quick instructable.
