This is my first instructions so please be nice. I'm using a battery powered and the other motor (the one you twist).

Step 1: Battery Motor

U should be able to make it using these pictures

Step 2: Non-Battery Motor

Same as last... Just follow the pic
The one I got was from a set... Knex 300 piece 20 model
Can someone PLEASE explain to me where these twist motors come from? I have one but don't know where it's from.
Thank you:)
<p>Cool! I like your profile pic :)</p>
