Worker flywheels reviewed




I bought two sets of these. One set to go in my sons Raven and one set to go in my Rapid Strike.

I’m quite particular about ensuring that testing is performed in a controlled manor.
For this sake I have a high amp adjustable PSU which I soldered onto the Raven for testing to ensure I had exactly the same voltage (12v) thought my testing. I also have a chronograph to check for changes in FPS

The flywheels are very well made BUT unfortunately the Raven lost between 6-10 FPS using the Worker flywheels over using the stock flywheels (With nerf dart residue on them)

So it looks like i wasted my money on these and will return to the stock wheels

Nice work, it's always good to see someone verifying a performance increase like this, instead of making half a dozen changes and then demonstrating on youtube that their blaster 'shoots harder'. Did you record any data in a spreadsheet or anything like that? It would be cool to see photos of your testing rig, if you still have it set up.

YES youtube videos wind me up. How is that testing. When hand held and measuring it and saying "look, now it shoots further" I'm like you could not keep the blaster at a constant height or angle to get an where near accurate data.

The next thing i want to tackle is Motors. I've bought a few motors which people believe to be better than stock but in my testing they are not.

I'm in the design phase of making a 130/180 Dyno. So i can see how quickly the different motor actually wind up ( torque ) and to what RPM and of course the all important factors of at different voltages cos of the different batteries people use

This test was using the stock motors then?

People thought that the "serrations" might increase air friction (thus slowing the motor down) and/or actually decrease dart grip.

If the problem is the former, more torque from the motor might help. If it is the latter, then these really are useless except if you are in desperate need of replacement flywheels.

Anyway, thanks for testing.

Yes stock motors at 12v

I believe others had predicted that these would not increase FPS because there is ultimately less friction area between the dart and the wheel now thanks to the serrations. I would really like to test ones without the serrations.

You could easily test this with a laser tachometer. They're pretty cheap on amazon.

could you sand down the serrations and make the concave a little deeper?? so that they are smooth but with a concave??

I imagine that sanding the serrations would make the wheels too small to catch the darts effectively. Perhaps maybe filling in the lower valleys with like epoxy or maybe even that rubberized truck bed liner stuff may help. Just a thought, too, that could potentially just mess 'um up even more.

Are they heavier then the original Flywheels. I am wondering if part of the decrease could be because they are too heavy for the stock motor and that they might work better with motors with higher torque.

Actually, Torukmakto4 tried them on "Blade" 180 equivalents and reported (here) that their mass is similar. However, even with these rather torque-y motors there was still a decrease in dart velocity.

He puts the blame on decreased flywheel-to-dart grip due to the serrations, which is totally possible.

If one wanted to try for even more torque, you'd have to use something like a 280 or 300-series motor...which would require pretty heavy modification of your blaster and still won't work as well as stock flywheels if the serrations are indeed to blame.
