The data is kept here. While the flywheels offer a significant noise reduction, I'm not entirely happy with them. They don't seem to output as much power as the Worker variants and they can be a bit picky on dart choices at full auto. I'll do a full and proper write up in due course. Smile

Don't want to sound stupid/obnoxious, but are you sure that data is right? as that puts them as worse than stock based on your past findings (worker/aluminium thread):

Stock Flywheels:
For reference, the aggregated data for the stock flywheels performance
Stock Mean Muzzle Velocity: 112.86FPS
Stock Standard Deviation: 15.87

Worker Flywheels
Aggregated Mean Muzzle Velocity:128.19FPS
Aggregated Standard Deviation:13.99
Aggregate formed from Trial #2 and #3

You're comparing RS to Stryfe there. Smile I'm working on comparison data now.

Phew! My bad! I didn't see the rapidstrike label on the new data.

Well, according to my own results they do actually make things worse! This is the same RS build as the Falcon 130 motor build. Same battery, same loom everything.

This is the original Falcon 130 motor data that I am using as a bench mark. I've installed and balanced the flywheels as best I can, they line up vertically on the shafts.

Stock flywheels:
Quote:

Rapidstrike 3S Results:
RS 3S Trial #1:
Data is presented in the first column.

Average: 98.5FPS

RS 3S Trial #2:
Data is presented in the second column.

Average: 115.27FPS

RS 3S Trial #3:
Data is presented in the third column.

Average: 110.19FPS

RS 3S Trial #4:
Data is presented in the fourth column.

Average: 107.41FPS


By contrast, I make the BP flywheels average 99FPS over 100 shots. Hmm...

What the BP wheels do offer, and I'm keen to stress this, is a smaller standard deviation. That means there's less variance in the muzzle velocities and more consistency.

EDIT: I'll wait and see if anyone else can replicate these results. I'll also look to putting them in my Stryfe and seeing what pops out since that's the better characterised blaster. I only put them in the RS because I needed replacements for the stock ones that were behaving like a sack of shite. At least the blaster fires now. Smile

EDOT #2: Just done some dimensional analysis - preliminary results suggest that the flywheel gap is wider ergo a lower muzzle velocity. I'm uploading images now and will post results in a moment. Smile

Flywheel dimension data As you can see, they're a mm smaller which makes for a 2mm wider flywheel gap. That might explain the discrepancy in muzzle velocity.

EDIT 3: Chrono data now complete with Stryfe data

EDIT 4: Aggregated data to compare across flyhwheel types

Thank you very much for doing all that!

I'm quite happy to take a loss in FPS if they go a way to eradicate that awful din.

Interesting results.  I wonder if the reduced crush improves the standard deviation, or it's because of a different variable. Hard to tell without another set of bp flywheels with larger diameter and same mass. Are they quieter than workers, then?

The standard deviation improvement is down to more precise machining IMO. These are matched and dynamically balanced.
They are quieter than workers.

That would make sense; less wobble would mean the flywheels will be more likely to occupy the same space at the same speed for consecutive darts.

Post matched worker fly wheels Reply with quote
I match up my worker fly wheels by weight. I have had some screwy ones and they go in the bin. Just takes time but that is why I buy in a lot at a time.

So I finally got some batteries for the micro-scales. 4.98g with foam build up compared to the Worker flywheels I weighed when I compared them to the Aluminium ones. Those weighed in at 3.87g. Now the extra gram could be due to the build up so I'll scrub this one in due course and reweigh but for now I thought people would be interested. Smile

EDIT: Moar data added! I took some MTB Hellcat 180s and shoved them in the RS with BP flywheels. I wanted to see if I could raise the muzzle velocity a tad but the results were disappointing. A great deal more foam spewed over my chronograph and no real FPS gain. I'm going to swap the Falcon 130 cage back in. If I can be arsed, I'll run the Worker flywheels in this build to see if they're worth it. I can't do a stock flywheel baseline because I don't have any functioning stock flywheels which is really irritating.
