and this kit was discountined

but they have this kit
http://www.redwolfairsoft.com/redwol...l?prodID=20438

what is the difference between this and a standard gear box...

maybe more easy to change the spring to change fps depending where you play... (like systema gun)

who can said me if i'm have understand the function of the kit...
and if I need more parts to complete this gearbox (because isn't clear on the page)

you can see more here http://www.tantec.ca/node/11

THANKS

Well you'd need gears for one thing...

[Screamer-]

but this gearbox is like a systema gun juste need to change spring to change fps of the gun

[Styrak]

Uh, that's true for any mechbox.

Thats sorta like an ICS armlite mechbox I saw once, where you could open it and remove just the top half of the mechbox to do maintenance on. Still not as easy as a systema set up, because systema uses springers already dont in cylinders. But this mechbox set up is very convienent if you change springs alot and dont want to go through alot of hassle opening up your MB all the time.

same idea as a systema or ics, but they are a fucking jole to put together. ive never done one myself, but watched 2 club mates attempt. youll need absolutly everything from a donor mechbox, selector plate, trigger mech, gears, bush, springs, EVERYTHING. all you get is the mechbox shell, adn it comes in... oh about 13+ pieces if i recall. id reccommend just getting a systema mechbox, or tradeing for an ics. i wouldnt attemp this. oh also the ones they got were the blue anodized ones if that helps, but they also wouldnt fit in any other metal body without modification except hurricane. one mate tried modding to fit, but he ended up fucking up the body and had to get a hurricane in the end anyways lol.

not sure witch are shown on redwolf, but they look like the 7MM type.
i got the PGC PRO-WIN 8mm (metalic grey color) and i love it to death.
there are a few things that you need to note down about it.
#1, you will need to grind down the inside of your M4/M16 body to make this mechbox fit.
#2 dont use the hop sleeve that comes with it. it seems that they made a mistake when they made the molds for it. the openning for the bb/nozzle is far too narrow and tight, the tappet plate spring will not be strong enough to puch a BB past the openning and into the hop chamber, causing back pressure in your cylender and slowing down your piston. if you fire in full auto with this hop sleeve, expect to strip the teeth off your piston (i went through 3 befor i figured out the problem). make sure you test any hop sleeve you plan to use by placing a BB on the openning, the sleeve should just be narrow enough to not let the BB fall through, but should be loose enough that a slight soft push will make the BB fall though.

#3 you are going to need to be carefull on how you shim up the gears, since the tolerances are so tight.
if you need help i can talk you through it onver PM.

other than that, this is one bad ass mechbox.
after i changed the hop sleeve i had no more issues at all with this mech box, this thing is a monster and now my VFC HK416 is a BB hose.

but I see that fit on hurricaine metal body it's true...

and I need to use a standard mechbox to get parts it's dut a expensive modification

there are just a few things you would need to get.
a switch assembly with trigger and sector gear leaver (the thing that disengages the switch in semi-fire mode), a cylender, motor and gears.
if you already have an old mechbox, just swap the parts.
it depends on what M4 you plan on in stalling this mechbox.
but most people replace most of their mechbox internals anyways.
i i know what gun your going to put this in, i gave get a better idea of what you would need to get.

as an owner of a pro win, i LOVE IT. you better know what your doing when it comes to putting this thing together, i didnt do it. (Raysaark did). It shoots beutifly, the hopup is seeld so there is no airloss and with a 6.04 its a dream.

you allso need a G&P body, i modified a guarder C8 body bit it didnt work the same and you couldnt swap out the spring with out taking the whole mechbox out. It is in a G&P body now and with about 2hours of fileing it fits and works great.

Hello,

i am from germany and this is my first posting so sry for my bad english :-)
also sorry for this bunch of questions /blush

i recognized this very interesting threat and have some questions about this prowin gb.
My gun is a custom thing: Classic Army MK12 Mod0 kit, G&P Akku Stock, G%P Body, PDI X-Fire 6,01 mm, KA M3 + extender and so on, no other internales until now.
so i am still building this beautiful gun and i want now procced to the inner tuning. the target is more than 600 fps (Guarder SP170), so all internals should be able to handle this power this for a while.
I heard that the 7mm version is crap, all questions belong to the 8mm version.

Here we go:

- Would those missing parts like sector gear leaver and the switch assembly fit, if i take them f.e. from a Systema complete mechabox (M170)?
- which gearset would you prefer? any experience with the prometheus super tourge up gears (not helical, to hard to shim;p)
- can i use both types of pistons? half or full theet?
- what about bore up cylinder-sets? would they fit? i guess the pgw nozzle could be a problem then ...
- @ Voodoo: i got an G&P M16 Metal body as well, i would love to take a look at some photos of the metal work (fileing) that is to do with that G&P body and the prowin GB. i hope you can help me out!
- is it possible to ... hm dont know the word ... lay the wire "backwards"?
like i mentioned, i got a G&P Akku Stock, so its an important question in the review from tantec.ca they took the wires to the gb-front. do you know what i try to explain?
- could anyone explain what exactly the hopup sleeve is, with an image for example? i can imagine but im not sure.


Thats all for now. you can see that i plan to exchange most of the prowin internals if possible. i like that box because of its look&feel and of course for the huge advantage to change the upper internals quite easily&fast

If anyone could help i would be so happy and perhabs i can return the favour!

Greetings from germany

- What is a sector gear lever?
- Yes, a Systema switch assembly will fit
- For your setup, I'd highly recommend either the Prometheus Max Torque gear set or the Systema Infinity torque up gear set
- You will require a half-tooth piston to work with either of those gear sets.
- You have no choice as to helical or flat with those gear sets... they ONLY come in helical teeth
- I'd also recommend a MOSFET for your setup so that you don't burn out your contact plates
- I'd also recommend a high torque motor, such as a Systema Magnum motor
- Bore up cylinder kits will fit - the kit comes with the appropriate nozzle, so no worries about the PGC one
- What do you mean by "lay the wire backwards"? Do you mean to the rear stock? The gearbox is built to allow wiring to either the front or the back of the gun, but it's easier to get it to rear power

I had it installed in my SPR, rear-powered by a Crane stock:

Perhaps he means anti-reversal latch?

I hope it's not crap; I just ordered one.
