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

with standard gears?

What is the current capacity of that 9.6v battery you're speaking of?
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.

Its a 9.6v 4500mah Ni-Mh sub c

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.

Ok, thanks for the info Illusion.

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.

The ASCU would solve all your overspin issues and allow you to run a big spring and big battery. You would have to still use a very high torque motor though

Edit: ASCU is V2 only right now

Ya i know I'd have to deal with the other issues, so would something like that be more suitable for an m110?

I believe that motor provides more torque and ROF than the original motor. If that's the case, then it could make it worse.

make what worse? I haven't ordered anything yet! lol, anyways all im really looking for is a motor with a bit more torque then my stock motor.

Overspin

I have that motor in an ASCU build and it doesn't have all that much torque. Pulling an m120, it can over spin and back spin way too easily. I've gone to the G&P m170 and it seems to control over/back spin without issue.

The higher the torque, the harder it will be to turn the pinion gear over by hand. More torque also means stronger magnets so it will stop soon when power is cut off. That G&P m120 turns way too easily by hand.

So, you used the M170 motor with a m120 spring? Also Im ordering to day so i would appreciate a bit more feedback if i can get it.
PS: will this mosfet work in an ak? the switch looks different.

Yes, it's a very high torque motor.

I am using the ASCU, in a G&P m120 gearbox, which eliminates the anti reverse latch. It fully depends on the cutoff lever and motor to start and stop the cycles. What was happening with the G&P m120 motor was that at the end of a cycle, the motor could not completely stop as soon as the power is disconnected. The end result is that the gears would continue to spin forwards and start a new cycle, I'll call it a slight overspin from built up forward momentum/energy, then when the motor stopped the spring would be slightly compressed and that tension would reverse the gears causing the back spin to neutral.

This was bad for me because if I caught the back spin with a trigger pull, it'd put a ton of stress on the motor. The TM eg1000 was significantly better than the G&P m120 but the m170 solved it since it will stop the moment power has been disconnected.

I don't plan on an ASCU, so i will have a anti-reversal latch. So what motor would you recommend for a m110 in that setup? (with a 9.6v batt)

Guarder Infinite Torque http://shop.ehobbyasia.com/upgrade-p...ype-motor.html
G&P M140 http://shop.ehobbyasia.com/upgrade-p...140-short.html
G&P M160 http://shop.ehobbyasia.com/upgrade-p...ger-motor.html

I personally run the M160 in my main AEG. Strong enough to pull a M160 spring, smooth and sexy sounding, power efficient, and will give you a much better ROF than your stock motor. Worth every penny.

thanks, i am most likely going to get this

run it with m110, and ill get my fps and rof that i want.

I'm not a fan of buying from US sites. Evike has a notorious rep for crap customer service. Shipping is more expensive and usually slower than from Canadian and Chinese sites and they often rape you in the ass with brokerage fees b/c many US sites use UPS. That and you're buying a rebranded Chinese motor so reliability is hit or miss.

you could still potentially have overspin. I have no experience with the Matrix but I'd go with a better motor.

edit: didn't realize you are downgrading to an M110. you could be fine with that motor but again, I have no first hand experience with it.

Ok, so maybe this G&P M120 then, although its high speed, would that be much of a problem with the 110? And The_silencer, what spring are you using with the m160?
http://www.airsoftpost.com/product_i...ducts_id=32257

Get the M120 here instead: http://www.airsoftparts.ca/store2/in...oducts_id=1269
Or if you're not in a hurry get it here and pay a total of $31 http://shop.ehobbyasia.com/gandp-ak-...tor-short.html
I'm not going to be holding your hand anymore if you insist on paying more for it at Evike. The spring I'm using gets me arounf 360 FPS so it's around an M100ish. I get around 34ish+ RPS on an 11.1v lipo, more if I'm using my Guarder high speed motor.

All i asked was your opinion on the motor, which is one of a few things being ordered from evike, maybe they have other items on sale that I'm buying, or specific gear and mags which airsoftparts doesn't carry?. Did you ever think i may be ordering more than just a motor? I'm well aware there are sites with better prices. If i cared about your opinion of where I shop I would ask for it.

Well since you sound so confident in Evike's amazing deals then be my guest. Though I can imagine it gets annoying waiting for Evike to send you a quote every time you update your order.

I don't know why you care so much about where other people shop. I've never had a problem with evike and got excellent support from them.

don't take this the wrong way but because of the bad service Evike has caused, most members on this site would avoid them. There are many threads about them here and what they have done. Feel free to search them up. THe_Silencer was just trying to warn you.
