Motor can pull m180?
http://www.airsoftpost.com/product_i...ducts_id=29143
It claims in the info it can pull an M180, I don't intend to use a spring that powerful EVER, just wondering if there's any truth to it? I'm juts looking for an upgrade from stock for my rpk to pull a m110-120 spring (somewhere in that range)

Sure, if you have extremely high torque up gears installed and a 12v battery...

ahh lol k, i assume it would be fine for a m120 on a 9.6v battery though right?

That depends on the gear set you have, you could cause energy build up problems and overspinning if you're using standard torque gears with a spring that heavy and a battery that strong.

So if i wanted to avoid getting new gears i should use a m110 or m115? or would that create the same problems with standard gears?

I've used them with 160 springs no problem

What is the cell size of that 9.6v battery you're speaking of? What is the chemistry type of that 9.6v battery you're speaking of? These are all factors in determining where to go with that, but in general, almost all 9.6v batteries are too powerful for any M110 spring. If you don't have the setup balanced properly, you can experience increased wear of your piston teeth, as well as greater arcing across your trigger contacts. Over time, this will literally burn a hole through the contact plates. |

Okay, that's a friggin huge battery and complete overkill for an M110 spring. You may experience the problems I mentioned above if you try to use a battery of that voltage, size, and capacity with an M110.
Ideally, you wouldn't need a battery any larger than an 8.4v 2400mAh sub-C Ni-Cad pack for a spring of that strength. That would be an upper limit I'd recommend. Ideal would even be a bit lower. |

so whats your spring recommendation for that battery with standard gears? if any.

None. It'd be an imbalanced setup. You could hamfist it and just slap it all together. It may work. For a while. But durability and longevity would be compromised. I wouldn't recommend it. Sell the battery and get something more appropriate for the FPS you're hoping to actually achieve. And tune the rest of the gearbox to meet that spring upgrade appropriately.

One more thing, a MOSFET would get around the contact issue with that powerful of a battery right?

Yes, it would prevent the arcing issues, but you still have to deal with the other issues which a MOSFET can't fix.
Some MOSFETS have active braking to prevent overspin, but the models I've worked with (Trigger Master) require you to fire several cycles in semi-auto to program the circuit. If you have overspin issues to begin with, this won't provide an accurate program. |
