Re: [FTC]: Help with shooting mechanism?

Our second idea was to pull back the balls like a slingshot, using surgical tubing. The problem we encountered here was that there was too much tension, and caused our metal to bend. When we lowered the tension, there was not enough power. We have another possible idea which uses a motor to pull back like a battering ram to release the ball. We are still thinking about our loading mechanism and have not tried any ideas for loading the balls.

Any ideas are appreciated!
I shall give you something we found works amazingly take a tetrix wheel and cut some Kydex sheeting into 1in wide and 4 inches long little paddles ziptie them to a wheel cut a space at one end for the plastic to fit on the wheel. Build a housing for it and it shoots perfectly.
