Worker flywheels reviewed

Posted Image

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

#344592 Stryfe FPS at different Voltages

Posted by Ultrasonic2 on 26 January 2015 - 04:24 AM

Here Is my test bed. As you can see i have my stryfe setup to an adjustable PSU so i can adjust the voltage to common battery voltages and with the crhono i know what FPS im getting.

Actually it seems i can't attach images so i can't show you.

Here are the results

100% stock Stryfe

4.8v (4x1.2) = 52.5 fps
6.0v (4x1.5) = 63.4 fps
9.0v (1x9v) = 85.7 fps

Now with the locks and resistors removed but stock motors

4.8v (4x1.2) = 56.5 fps
6.0v (4x1.5) = 69.3 fps
9.0v (1x9v) = 90.4 fps
11.1v (3x3.7)= 99.7 fps
14.8v (4x3.7)= 96.8 fps

The interesting thing is the reduction at 14.8 the rounds just vary so much on a vertical plain that it was impossible to get one through the chrono without it hitting it.
Also based on the range test i could only get 1 out of a lot of shots to travel further than at 11.1v. It's possible that all of this would be "better" if an extended barrel was added.

I presume the fundamental problem is that at this voltage the motors are unable to keep their RPMs anywhere near the same to ensure a consistent vertical plain.

At this point i would go with three 3.7 14500 batteries (11.1v) and one spacer OR the "Safer" option of possibly using four 14500 lifepo4 3.2v (12.8v) but i didn't test that voltage.

I will now be replacing the motors with high performance 130 Atomic ball bearing motors. This should at least drastically reduce the noise the gun makes.
