Please help - launcher issues.

[ksafin]

Hello everyone.

We've been prototyping our launcher since build season started, and we're not happy with where we are.

We've done a variety of things from changing wheels, changing gear ratios, speeds, changing compression, putting on a roof, changing angle, using double wheels, etc.... all to no avail.

We're getting meager distance out of these - 20 feet max. That may not be too bad, but the 20 feet max is only achieved if we fire the frisbee at a height of about 3 feet: in other words, not fast enough to get into a 3 pointer if aimed upward.

Here's a few images of the launcher.. hoping we can have some guidance. Thanks a ton.

Gear ratio on the front wheel is roughly 1:2.375
Gear ratio on the back wheel is roughly 1:2

Both being run at a bit over 12V via direct battery hookup.

We're just getting a bit frustrated because we've seen very very very simple prototypes work much much much better and have not been able to achieve a satisfactory result with hours upon end of adjustments and changes.
