Need Help with an Upgrade Project.

[Sarge127]

Hey guys,

Recently i posted about my AEG, now i want help again. My stock internals are all worn out now and buying upgrades that are TM v2 compatible are hard to find not to mention i don't read kanji or whatever. The gun i want to upgrade is my troy mrf-c, i was actually gonna purchase king arms upgrades, but the dealer said non of the internals from K.A. would be good for my AEG. so i tried others such as G&G, Classic A. and other brands.

So i finally decided to ask for help online, my dealer said if you want something that is durable and doesn't shoot as fast as you want. Might as well go with systema. What are your opinions on this matter?

-V2 Gearbox (stock piece by echo1).
In everything. its by E1.

lol... find a new dealer.

Don't waste your money on systema.


You're asking a rather broad question... and the answers will vary depending who responds... My question is what is your end goal for the gun? 400 fps and 15 rounds/sec? 400 fps and 40 rounds/sec? It can be done with tuning components and some funds. And none of which involve systema or the amounts of money it costs to buy systema parts.

What is the gun shooting for fps and rof now? Have you opened it up to inspect anything?

Sight unseen, if all you're doing is replacing gears and piston:

core gearset or lonex gearset standard ratio is probably 18:1 20-40$
shs 15 tooth or lonex red piston 10-20$
a set of shims 5$ if you get ripped off.

some time or money... though don't go back to whoever told you to buy systema parts to do your install. Time if you want to do it yourself... money if you don't have time. Find someone who knows how to shim. Your gun will be running as it was before.

Those are the basics.

To make it so you'll never blow up a piston... a sorbo pad on your cylinderhead and dremel off the 1st regular sized tooth from the pickup tooth on the piston.

IF you want more, you could go with a 16:1 gearset, that will give you faster rate of fire and faster trigger response.

What spring is in the gun now? 100? 110? 120?

If you want silly rates of fire... a new neodymium magnet motor.. shs motors can be had for 35$ or so... and they will equal or outperform a systema magnum motor for 3x the price. A lonex motor will be 55$ and well worth the money, provided you match the right spring to it. Too weak and it can cause problems.. neo magnet motors are just way to strong to be using 100 springs. But there are ways to get guns to shoot <350 while using neo motors.

If you want ridiculous rate of fire... a simple mosfet and an 11.1v 20c lipo will give you 30 rounds per second...

Even more retarded rate of fire, go with a 13:1 gearset... or 10:1 riot seigetek (getting into systema money with those.. but they will eat anything you throw at them) Then you're looking at 40+ rounds per second with the same bits as above.

IF your compression components need to be replaced... well I like the lonex POM pistonhead... lonex or SHS cylinderhead and nozzle... best to match the same nozzle and cylinderhead imo so lonex to lonex or shs to shs.... those bits shouldn't cost you more than another 40$ tops.

Lonex and SHS ALL THE THINGS!

But seriously, there's nothing wrong with replacement parts like that if you just want a replacement (but try to keep upgrades within the same brand or 2 brands at most, sometimes upgrade parts don't play well with other upgrade parts).

So if you've got an E1 troy it should be OEM'ed by either CYMA or JG IIRC.

I'd recommend Lonex, SHS, Guarder, or Modify. SystemA is good but overpriced IMO (although I do have a SystemA bucking in my hop up). Hell even Guarder and Modify are overpriced in terms of price/performance compared to Lonex.

Thank you for your perspective on the problem! My AEG is shooting 290-320FPS using an M90 Spring, my CQB Arena Requires everygun to shoot under 350, due to how close the environment is.

Shimming won't be a problem, i got past experience shimming different things.
Lonex sounds good enough. With you hearing the problem now, i think you'd be able to describe the outcome if i did a high-torque motor with a M90. the gear set however will have to be a standard, im not looking for a crazy ROF.
Just a simple gun with simple internals.

Lol you should hear the gun, i did get a look at the internals, i was scared as &*** to open it first time. looking at everything the smell of some burnt plastic or whatever reeked out badly. the piston was chipped, and the cylinder was loose, judging by that im most likely going to say that is very bad. However there are no problems with the gears, besides they were made by some Eagle company i never heard of.

Anyway i Can PM you everything just by thinking of the outcome it might get too... Technical.

[L473ncy]

Eagle as in "Eagle Force"? I know their motors are supposedly awesome. Haven't heard much about their gears though, I'd assume they're the same high quality as their motors.

An easy drop in would be to buy a Guarder "air seal" FTK kit that comes with a piston, piston head, cylinder, cylinder head, and air nozzle. Pretty much has all your compression components down pat and keeps it all one brand to keep tolerances tight.

[Re1ko]

Lonex parts all the way. They even have a tune up kit similar to the Guarder ones, cylinder, cylinder head, piston head and nozzle. I have one in my G36 and love it. I will be getting gears, and motor from them next, maybe even a hop-up unit.

[lurkingknight]

oh, I'm quite aware of what will happen with a super high torque motor with a m90 spring. :P


In your application, probably a shs 7 (metal) tooth piston will work, or again the lonex red since it's also a half and half piston. For motor if you really need one, best stick with a ferrite motor at that fps... unless you want to put in a 120 spring and shortstroke 2 teeth off the sector gear, then you can run a neo motor without issue.

I have a p90 on my bench with a shortstroke swiss cheese setup and an shs torque motor... it's viciously fast without even trying... I chronoed it at 28 rps on my 20c 11.1... it would probably hit 30-31 with the 30c I have. It shoots at about 330 on average.

The new Eagle Force isn't too bad. It's not the same company that made the motors about 10 years ago though. They make some decent internal parts, we're sampling their stuff right now. They're about the same as SHS and Core.

I think the only things I would buy from Systema are either PTWs (even that's sketchy) and *maybe* their hop-up units, but only if I really had to. Everything else is overpriced garbage. Don't even talk to me about their "ENERGY" line.

Thanks for all your support everyone, now with this proper information i shall continue my project. :P Finding Lonex parts will not be a problem, just got to find a site where they are in-stock and not out of stock.

Potentially dumb question: What is the problem with using a high torque motor with a 100 spring?

I'm going to guess that over-spin is an obvious complication which may arise with such a setup?

I ask because I have a Guarder high-torque driving an M100 spring wrapped in a Modify Torus V2 mechbox.

Thanks in advance for any assistance!

Cheers - Dan

[lurkingknight]

overspin is possible... but I think what is more feared with super high powered motors is preengagement... the gear train may come for a second pass before the piston returns... though according to maciek, it's 6ms return time even for a heavy piston... so jury seems to be out on it. Lonex themselves seem to believe there may be catastrophic issues running less than 110 springs on their motors, and standard practice on asm seems to be neo motor with shortstroke sector and a heavier spring to achieve cqb fps.

Your guarder high torque is a ferrite motor... a neo motor will run circles around it and pull ridiculous spring weights. A 100 spring on a guarder torque motor is nothing special.

[danhay]

Thanks very much for the extremely prompt reply and helpful advice. You must be in work avoidance mode just as I am! I'm just learning how to maintain and upgrade AEGs and I very much appreciate the sagely advice available here and on ASM (although I don't spend nearly as much time reading ASM as I should).

Cheers - Dan

Talk to Stealth. He has that down pat.

Either that or Clandestine Airsoft but he's located in the US and you'll need to pay for shipping and possibly customs/duties/taxes.

Our restock should land next week.

[lurkingknight]

can we just name stealth clandestine north? :P
