On top of that, the motors will shut down if they get too hot (for safety reasons) which tends to happen if they are under a lot of stress, i.e. firing balls under a 15:1 gear ratio.

However, if you have a spare Fischer Price motor and/or Victor 883/4 laying around, you could probably wire that up and get it to launch a softball .

I found that the vex motors will work for shooting as long as you have a good gear box with as little friction as possible. here is my shooter, it shoots balls 8' up and 7' out using two motors geared 35:1 my motors never shut down.
