Help, I am trying to get the disc to launch. However, it gets stuck on the flexi wheel. Or when it does launch, it doesn’t go very far. Please help
too much compression? (which could explain getting stuck at flywheel… Also when stuck, does the flywheel stall? what gearing and gear cartridge?)
those details will help debug.
how is it running at 550 rpm? With that gear ratio you can only get 166 with a red cart, 333 with a green, and 1000 with a blue. just curious
It looks like you have 5" between the flywheel and the opposite side of the launcher. You might expand that to 5.5" or 6" with some foam opposite.
Also, you are stating 550 rpm, but showing a 5:3 ratio… which is 333rpm with a 200rpm cart or 1000rpm with a 600rpm cart. So, not sure what you are using. That said, if you do some searching around the forum, you will see that 3000 rpm is common – you need to increase your flywheel velocity.
On the programming I put the blue cartrage at 550 of 600
The flywheel does stall, it is a blue cartrage at at gear ratio of 5:3
On the programming I put 550 rpm out of 600
On programming I put the blue cartrage on 550 rpm out of 600.
So given small opening 5" you are compressing the disc too much, so blue cartridge will give you speed at the expense of power - hence the stall. Generally, with flywheels you will want very high RPMs and just enough compression to launch the disc. The flywheel will lose a lot of energy after launching a disc. So you will either have to account for that by letting it get back to target RPM (and not feed more discs) or add weight to flywheel to compensate for loss of energy.
Fun stuff!
Just because you set the rpm in the code doesn’t mean that it will spin at that rpm, gears will change that. Also, what I’ve found is that 3000 rpm is generally the minimum rpm to launch a disc. I would make the distance between the flywheel and the other side of the launcher about 1/2 inch less or 1/2 an inch more than the diameter of the disc (5.5 inches). It will go farther if it is squeezed through a bit.
