We actually did that already and it didn't help. What is the compression your team use and how much of an arc that the ball contact the hood. Thanks.

The inertia problem can be fixed with a flywheel. The design of a stealth wheel (partially hollow) also makes it easy to mount additional mass right into the shooter itself. And if your problem has anything to do with compliance, I'd say it's likely you have a problem with too much compression...

We were hitting the roof of our building quite easily at full power with blue 4 inch diameter stealth wheels. I don't know the exact number but its 25 to 30 feet of height. Couple that with extreme accuracy (hitting the center of a roof tile many times consecutively) and I'd say stealth wheels are a-ok for shooting.

For a specific set of adjustments we tried to make to optimize success rate, we find that when the seams of the ball are perpendicular to the shooter wheel, it is much more consistent than lined up horizontally.

Now I'm curious how you designed a hopper and indexer that could possibly line it up in a reasonable manner.

That's easy. By hand😃

so what compression are you running?

I agree. Just about any wheel can be used with success if the rest of the system is good. But if the OP is having issues with Colsons, I doubt stealth wheels will be better. Grnated, switching to compliant wheels probably won't make all their shooter problems go away either, but compliant wheels may be a better wheel for the rest of their setup than Colsons or stealth wheels.

Stealth wheels perform dramatically differently than Colson wheels in terms of acting as a shooter. Please don't speak from experience if you don't have said experience - at least qualify your statements with "I think" and / or explaining why you're making the assumption that you are.

All that said, I've had great experiences shooting with compliant wheels, I think they're great for this game piece.

Our compression we have been varying and due to welding right now, I've been separated from my team. I know that it is not a lot. The arc of the hood is very little.

About an eighth of an inch, maybe a few thousandths more.

Our one wheel shooter prototype was an 8 inch wheel powered direct drive with a cim and we had plenty of distance and had some accuracy issues.

Our 4 wheel shooter prototype was 4 - 4 inch compliant wheels on 2 shafts powered by 2 mini cims. First prototype testing we hit the same 2" pipe along our ceiling for 10 shots in a row with plenty of power to spare. The pipe is about 12 feet straight up.

We did no further tests.
