Those are some pretty bonkers numbers. Packing all that into a 132 sized motor is going to generate a lot of heat with not a lot of cooling area. Some more sanely-specced motors will probably last longer.

 

Both speed and torque are almost certainly overkill. What's your use case here? Just single stage, or is this going into a second stage of something or an afterburner? If it's just single stage, I'd say those are going to move way faster than they need to, and you'll have extra dart damage without any benefit over something about 10,000rpm slower.

The burst rating. Continuous is... exactly what it sounds like. The battery's ability to deliver that current without stopping. Burst is a short term limit, although what exactly constitutes "short term" isn't standard, as far as I know. Anyway, As stall current isn't something that is going to be drawn by your motors for very long, you can generally compare burst rating to stall current.

I've heard of those auto kits having too little stroke, but not to that extent. What darts are you using?

 

Second what Cthulhu said. I'm not aware of a silver canted cage besides the DRS cage, which you're obviously not using.

How well has the solenoid pusher been working for you? I've been reading up on those a bit, looking into a more compact bolt drive, but still have a bunch of questions. They seem smaller than the stepper, but have some problems of their own. lachlan_s's looks smaller than the Aliexpress solenoids, but it looks like it doesn't fail open. I haven't seen enough testing of either of them to know much about reliability or stable cycle rates, and both of them inherently impactful and shaky. At the end of the day, I really doubt there's a perfect solution, just different tradeoffs, as is the case with any engineering project. The stepper may be big and heavy, but damn it's smooth.

 

Definitely do a brushless build when you can. There's so much freedom in the design of the cage and flywheels, and the hy-con system in particular has amazing velocity consistency and is easy on darts. And the sound alone is worth the effort to make one.

I used an ancient 6 cell (7.2V) NiCd in my rapidstrike running Blades for a while. All the stock switches died, but that might not be an issue if you're using stock motors. The battery never gave me issues, but I did notice a performance bump when switching to 2S LiPo. The trigger felt much snappier after the switch.
