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.


In Topic: Selectable voltage

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.


In Topic: Why a 2s 7.4v Lipo Charges to 8.4v?

3.7V is the nominal voltage, around where the battery spends most of its lifespan. Look up lipo discharge curves and you'll see that they lose voltage very quickly early in the discharge cycle, then flatten out for a while and stay near 3.7V for most of their life, then drop off like a rock again at the very end. Full charge for a lipo cell is 4.2V.

What part of the hopper system are you planning to improve with this? A hopper has zero moving parts and no where for air to leak besides out the barrel. I'm going to need a little more information on what you're trying to describe.

Anything from the koosch ring-firing line of blasters are rare. Not supermax 9000 rare, but still rare. If you want to fire the original ammo type, I think there are some files for the koosch rings on thingiverse. If you are looking for overall info on the series, look up the tornadobow. Its in the same series but is way more popular for its ergonomics. The original rings are so rare I dont think anyone on this site right now owns one, and many of us have never even seen one, on video or otherwise.

 

I have a few of both sizes, but I'm more interested in finding a blaster to fire them than selling the rings. I'm sure I'm not the only one here with rings.

 

Very interesting. Thanks for the info! I've seen some people make them out of duct tape, and if a lot of effort is put in to them, they seem to fire well. I made some out of duct tape (and little effort) and I only get around 20-25 foot shots and they curve to the right. I've seen some smaller ones rings on Amazon that come with some little pistol thing. I might try those

 

The Power Strike can fire both sizes of ring, and I've heard the rings on Amazon are the same size as the small vortex rings. I cannot personally confirm that though.
