Here's some ideas for you:
- Replace the big CIMs with smalls ones - there's a few pounds right there (they have more torque too)
- Ditch the compressor and just pre-fill- thats about 6 pounds
- The big A-frame you've got going looks kind of unnecessary. You could probably make it much smaller.
- It looks like you have way more metal than you need on the hopper.
- Those are some incredibly massive transmission plates and mounts. Drill big holes in them.
- You can use much smaller chains. Ours are about half that size, and we've never had problems with breakage.
- You might have to ditch that machined nameplate on the front. It looks like it weighs about 10 pounds; at least use thinner material.
- It looks like all your square bar is 1/8" walled, and you can definitely get away with 1/16". It's probably a bit late to change that though.
- If you can, machine down the gears in the gearbox. By taking down the hub and putting a few holes in them, you can cut them down from about a pound each to about a third of a pound.
- Fill the air system with helium!!

- Edit: you can run the shooter with only one motor, with a chain to each wheel. We are running ours (same horizontal setup) with a single FP motor on a custom gearbox.
