About: My real name is Ryan.

Intro: Knex Bazooka

This is a new design, it is powered by rubberbands and huge orange motor. It does have a true trigger, for people who only care about the triggers, but the trigger does take down 5 ft from its range. Its range is 25 ft, and it takes approximatly 30 sec. to load with trigger 2.5 sec to load without trigger. There are 3 speicial parts in this gun that some of you may not have.
one: the red track
two: the purple cart that runs on the red track
three: the orange motor that pushes the cart out.
All three can be found in the rippin rocket roller coaster set. Ill be doing this instructible in three parts. the trigger, the cage, and the barrel.Enjoy.

    SO buy a $40 used rippen rocket off of ebay (including shipping, buy used-it is a hell of a lot cheaper) and stop complaning.
