Lowest RPM for Single Flywheel

VEX V5 General Discussion Technical Discussion
1

Has anyone found the lowest RPM to launch balls on? I’m looking specially at a single-axle flywheel with 5" wheels.

I’m not looking for gear ratio, but rather the exact rpm you launch the balls with

2

Couldn’t say about the lowest, but our launcher needs:

2176 RPM for the full-court
1888 RPM for the mid-field

3

I am running around 1000 for bar shots, but I know I have to bring my compression down a bit

4

We used to run 1:21 and still overshot by quite a bit at max speed.

5

Lol but you are very good at getting the axles to be as friction less as possible

6

Full court my single flywheel with 5" wheels spins at 2217 rpm.
Midfield is 1783.

7

What angle are you using for this?

I’m at about 50 degrees and I use 2300. This is the theoretical minimum needed for 45 degrees.

8

Is there an equation you use to get the theoretical minimum?

9

I didn’t calculate, it but someone earlier in the season calculated about 24-26 ft/s and that comes to around 2300 rpm on a 5in wheel.
