Appreciate the reply, gives me confidence.
 
Took it out over the weekend and performed really well, super happy with the build. and NOTHING broke!!

By the numbers, your RPS is correct.
 
24,000 / 60 / 13 (approximate ratio, not actual) = optimal cycle speed. That means the speed the motor should turn the gears if the gears weighed nothing and the spring had no resistance. Optimal speed is about 30 RPS.
 
However, the gears do weigh something and the spring does provide resistance. This means we have to factor in a final variable: efficiency. If you're getting 25 RPS, and assuming your motor is exactly 24K (most motors can be off by up to 1K, and some are far worse), that means that you're at 81% efficiency. This could be better in a gun as low powered as this, but it's fairly respectable, and indicates that you probably don't have any huge issues.
 
That being said, here are some caveats:
 
Motors can perform at "high efficiency" on paper but still be heating up overly fast due to bad shimming or whatnot. The motor can be strained but still put out full RPS.
 
Motors can be badly off-spec in terms of speed. For example, it's well documented that the ASG 30K Boost is actually 35K in practice, similar to the 16TPA 35K Tienly GT. This can lead to issues with inexperienced techs who have a faster-than-it-should-be motor on their hands.

There is no more noble cause.  I'd call it a win and move on, airsoft is more of an art than a science.

Nah not really any reason, just enjoying learning to tinker around with my gun, so thought it would be a good target to aim for.
 
I don't think I'll put anymore money in to the gun for now. I'm happy where its at. Was just worried I had really fucked up somewhere.
 
I *think* I've done a good enough job. Just hard to tell

Cool! Wonder why they changed the baseplate design from the EPM?

Just checked resistance on my motor, its showing as 0.7-0.8 ohms. Meaning in theory it needs 12-16 amps...
 
My batteries should be outputting more than enough to supply the motor.
 
Unless this £10 multimeter from amazon is reading inaccurately....
 
  
But yea I'm enjoying it to be honest, just a bit scary when I have no real base line for "good" or "bad"
 
Gets me questioning everything I've done, like my shimjob, still paranoid its awful!
 

as @Skara remarked, paper and reality can be very different due to all the little variables.  try a new battery, if you're hitting double-shots etc then maybe go up to a M110 spring.  chasing rof is a lot of fun 🙂

Yea that had crossed my mind too, sound check is showing as the same as IRL ROF.
 
Thanks though ❤️

Best new setup ive implemented a few times with great success is;
11.1v Warhead standard speed or other quality brushed 25k motor with stock gears (18:1) and helical bevel.
Just makes the sweetest sounding action with zero stress.
Will put out 19RPS on an M110 so is the goldilocks speed if you ask me
 
Obv this doesnt help the OP with his gearbox of choice currently, but hopefully good info for what guts to use.
And obv you will want a suitable mosfet at least or Perun Hybrid/Gate Titan etc to optimise.
