So... i was browsing around dealextreme because they have free shipping to canada and im in canada, when i stumbled upon this: https://www.dx.com/p...3v-2-pcs-200979 first of all, at only 3v, it spins at 20000 rpm!!! in comparison, the solarbotics rm2 at 3v spins at 17000 rpm. the best part about these are that they are whopping cheap! less then $3 for 2!!! and yes they are 180s im going to be putting these into my demolisher and im probably going to be ordering about 3 pairs.

I'm anxious to hear more about these. These could be the best thing to happen to flywheels (like, ever). I guess we'll have to wait for one of our electrician guys to respond :T

Please look for the next video on my youtube channel CS- Tiff. I will have a video of the first 180'd demolisher there.

It's a little difficult to tell, there's so little information about those motors on the website, but I suspect that they have very little torque and will take ages to spin up. Especially considering the stall current of the first one you linked is only 0.6A. Either way, I'd be interested in seeing the results.

wow. being a noob with electronics i didn't know that the stall current mattered. for all those canadian nerfers out there, heres some nice ebay 180's with 2.6 A stall if thats good enough

Because this is a relatively low torque application, I recommend a single D16Z6. If you are really crazy about it and think you need more, then go ahead and drop in a B18C5, but the wiring is a pain in the ass. Don't even bother with the H22A5, they are just too big to fit, and don't offer any real advantages. Also, lightened flywheels can be awesome, but can be dangerous.

Also, If i use a microswitch rated for .5 amps, will some nimH cells or a 2 amp lipo burn it out when i get some crazy stall motors?
Another question is, why are lighter flywheels dangerous?

and i dont get why lighter flywheels can be dangerous

Normal NiMH can only push at best 1500mA Normal AA can only do .5A or 500mA. If you use a microswitch rated to .5A only .5A can pass through it without generating heat over that can go through it but it will heat and can fail. Example of what can happen you have a stryfe you have blades in it low resistance wire and use a 25-50c battery pack then you use the switch that came with the stryfe the motors will attempt to draw up to 10A when a jam or dart hits the flywheels the only thing your gun has that cant handle that type of load is the switch. When the motors start pulling the amperage the switch passes it as best it can as it exceeds the switch it gets hotter and hotter until thermal failure occurs something burns or melts.

Stock motors with better wires and cleaned up circuits will have little issue with the stock switches and amperage under 3A if you upgrade the brushes/motor and raise the voltage a better switch might be in order.

This is why i feel unless your going for the full rebuild you dont need a lipo pack if your doing wires, motors and a lipo pack why keep the old switches might as well change them too.

The axle are a bit long you will need to cut them probably.
