I ran 1 with 600 rpm but I forget the gear ratio for turning point. It would slow down cycle time but we also had it very compressed since we need the force to shoot from back court
My concern is whether air drift and air resistance will have a greater effect on the disc, as compared to the previous balls (nbn and tp) that we dealt with previously.
If yes, then do we need to spin it out at a higher speed?
the fact that I am also messing me up makes me hate myself
We will test that more as we move into the full season in the fall. From our experience with fly wheels in the past, we feel that there is a sweet spot with contact of the flywheel (Hit top speed but no more) that we will need to figure out.
We ran out of time. It was the end of our semester and those that didn’t move out already, were taking finals.
How much do your 3D printed frisbees weigh?
I’m not too familiar with fly wheels. What is the problem with a 600 RPM motor geared 1:7? AKA how fast could the fly wheels go without being dangerous? Or at how fast are they useless? [This is an actual question as I’ve never built one before.]
I hope you mean 7:1. Always put the driving gear before the driven.
What diameter and durometer are those flex wheels?
Yes. I was asking about 4200 RPM. Also good to know
It is not about how dangerous the flywheel will be. Even though if it is not done properly, and the flywheel get detached and spins off the axel it can be pretty dangerous.
Looking at BLRS video, it is obvious that 1 motor is enough to shoot the disc over to the goal. But I am concern about the cycle time, or how fast the flywheel can “recover” or pick up speed again. Coz we are looking at continuous, rapid firing of 3 discs. But each time the flywheel shoot off the disc, the flywheel’s momentum will be transferred over to the disc, and hence slowing the flywheel down.
There are actually lots of good resources in the forum regarding flywheels.
You can dig around for NBN and TP seasons.
What i can offer you is my shameless plug on this informal, “definitive” guide/thread on flywheels
Do bear in mind that all these were using cortex equipment and 393 motors (which were much weaker than the current v5 motors). And even though the thread started off as a robot reveal, it eventually led to real good technical discussions ( > 450 posts) on various aspects of flywheel design, etc.
Hope it will help you in your journey of learning about flywheel.
How did you get your flywheel to shoot so far and consistently? We have a similar design with the same ratio and can only shoot it four feet.
roughly 30 grams
4" 60a flex wheels
Solid build so it doesn’t shake too much. Extra bracing makes sure that the compression is consistent too. Beyond that, good editing, this was still a rough prototype.
love the honesty. lol
Are flex wheels necessary, or would other wheels work?
Aren’t the 60A ones black? Yours look like 30/45A.
I was mistaken. I think they are 45A
you need compression somewhere. Since we were working with 3D Printed discs, we needed compression in the wheel.
