Systema gears?

[Tiburon]

Hello!
Im about to upgrade my G&P M4 (8mm gearbox)
The spring will be Guarder 120/130 , M160 motor, beaings spring guide and 11.1 1300mah 20C battery ,prommy barrel, Systema + scs and all the rest is stock.
Now I just wonder what gears should I get?
Systema Original ratio or Torque up? Im talking about the flat gears...
What is the hotest spring that the original ratio can handle?

Thanks

I'd go for systema helical. They're the strongest I ever tested.

[Tiburon]

For helical gears I will need new piston - something I dont want right now so I stick to the flat gears.
What about my other questions?

[DarkAngel]

You dont need a new piston (Half tooth) for helicals. Its "recommended" by the manufacturers that you do, but Ive ran helicals in the past with standard pistons without issue. Full-Teeth pistons are utilized for gearsets under an Infinite Torque-Up set as the sector gear driven teeth are smaller in diameter than the piston pinion teeth.

Furthermore, Avoid Systema Gears like the plague. They were great once upon a time, and if you have an older set, they are like gold. However all the new systema stuff comes out of china now, the materials are shit and they strip/shear teeth off like crazy.

I regret selling my older helical set.

Go with a prom torque up set. Thats my recommendation.

[Tiburon]

Thanks for answer.
The Systema is already above my budget, Prom gears is very expensive something I cant afford ...
The Guarder original ratio should be better than Systema?
Or what good gear set until 60-70 bucks?

[DarkAngel]

Spring for the prom, is worth it.

Guarder gears are improperly tempered and are known to shatter. They are brittle due to the improper tempering process.

Gears will not be something you'll want to cheap out on, considering if you buy a "cheap" set for around 70-80$, and they break, your out quite a lot of money, plus the better set on top. Just save for Prometheus gears.

[Tiburon]

OK you convinced me :/
Ill get Prometheus ...
My spring is 130 so what set should I get? Normal Torque (wich is standart ratio) or Double Torque up(wich is Torque up)?
Btw, those gears are flat or helicals?

[DarkAngel]

Prom only makes flat unfortuntely. If possible, I would have liked to get helical prom gears too, but alas, they dont make em.
Benefit of helicals is that they mesh nicer and are a bit more quiet, but they shim differently, and imo are a pain in the ass to do.
Systema helicals come with an instruction page on how many, which and where the shims need to be put, but dont follow the guide. Even with systema boxes, the shimming instructions are almost ALWAYS off, causing the box to be misshimmed.

Saying your spring is 130 means nothing to me. Id need to know what brand and subdesignation. (ie. Systema M130, Guarder SP130, AS 130%) etc etc.

I always recommend the Torque up sets, you shouldnt need a double torque unless your running a REALLY heavy spring. In which case, considering your not AV'ed and are brand new to the sport according to the sign up date, I would not feel comfortable with you using on any of our fields. Be aware that most fields have a 350-400fps field limit. 350 for indoors, 400 for outdoors. Some allow up to 425, but its very rare in ontario, but some other provinces have different limits.

Most people have their outdoor guns at 380-390 to allow for temperature variances. Remember, 400 fps is a limit, not a goal.

[Tiburon]

Are you sure its flat? someone has them and can confirm these? I saw in few forum said it helicals...

The spring will be Guarder sp120/130.

About my FPS, be cool I leave very far from you (Europe)

So now, the qustion is what set to pick up?
Here is something interesting I found:

PROMETHEUS
High Speed 16.45
Standard Torque 18.72
Double Torque 23.78
Triple Torque 25.84
Max Torque 36.81

SYSTEMA
Ultra High Cycle 15.50
High Speed 16.45
Standard 18.72
Torque-Up 23.78
Super Torque-Up 27.50
Ultra Torque-Up 36.82
Infinite Torque-Up 45.00

According to these, what set shuld I pick up ?
My set up is G&P M160, Guarder SP120/130 and 11.1V lipo.

Promtheus torque series are helical... not sure about their speed, I haven't used their speed gears.

With a M160 I'd go single or double torque.. but I'd also put a trigger master in so I can adjust how fast or slow it shoots.

[Tiburon]

I found that the Standard Torque 18.72 is flat and higher sets is helicals.
My last question is: Promtheus Standard Torque can handle SP130 spring for a long time?

[DarkAngel]

Standard torque are flat, not helical. Im running em in 2 of my guns as we speak.


Guarder SP130 is a bit heavy, I would use a double torque.

Edit : Double torques appear to be helical however. hmm didnt know that.

[Azathoth]

PM me. I have parts not listed in my sales thread that you may be interested in I have 3-4 or so extra sets of gears, (systema torque flat, systema high speed helical, Prometheus triple torque helical full sector, Prom double torque helical, stock TM v6)

I personally buy Prometheus over other gear brands because the quality is rock solid. In my personal, high end builds it's either Siegetek or prometheus gears ONLY. In my el-cheapo builds i'll try literally anything to avoid spending money.

The set of gears you should pick up depends on your budget, your willingness to deal with issues down the road and your performance goals. I believe Prometheus Torque gears are rated to M130 spring max. It's only going to hurt your ROF if you go up one level of torque but possibly save your beat up gears.

I have been running a 7yr old Prometheus Torque up gear on one of my aeg. No signs of wear. Built like a tank.
