Sort of hoping they will either come back in stock or someone will have two that they are not using.
I guess...lesson learned...we'll buy a ton of stuff in the off season just in case for next year.
We may go with the AM gearhead motors...
So we are doing some math to try and figure this one out...
We want the ball moving at up to 27 fps when it leaves our shooter...
So...we figure if 50 percent of the wheel speed goes into the ball as it passes through the shooter...
so rotating 8 inch diameter wheels 3 times a second? so basically we would have to have the wheel spin 4 times as fast as the motors?
my brain hurts at this point...

Here is another option, take the first stage (or two, depending on what ratio you want) of plastic gears out of the big plastic FP Gearbox, and you can build a very simply gearbox from those gears. A couple shafts, some bearings, 1/8" Aluminum plates, a little milling and BOOM! FP Gearbox.
