DSG Gearbox

[adox]

Does anyone know of people or companies that make and sell drop in dsg gearboxes. So that I can simply remove a gearbox and install a new one that is premade with a dsg???

DSG is over-rated imho

first of all DSG's are half stroke so for barrels up to say 250mm

of maybe pushing 275 - 300mm if using 9T sector from Seigetek (not cheap)

Hence most DSG builds are AK74 or G36c or MP5k or short/stubby M4's

BUT.....

But before you chuck £100 down the drain - give that to a tech and you will have made a better decision

Seriously - do not buy that gearbox, avoid buying the gun itself & perhaps forget DSG-ing your Nuprol

Maybe buy this std box....

and maybe do a few tweaks with a nice motor....

should scrape by without needing a mosfet for a while imho on 7.4v

well trigger contacts should last longer than the Nuprol's micro switch contacts I reckon

more zest/snap blah blah blah

could look to fit 13:1 gears at some point & mosfet perhaps (draws a bit more juice)

but reckon that should get you about 18rps on 7.4v on std 18:1 gears

I mean you could at some point swap the std sector for a DSG sector but tbh I wouldn't

but do-able, though need bushings and a bit more work - but again DSG's are for short/med barrels

I'd be tempted to use your gun as it is tbh and not chuck too much money into a Nuprol

if you can help it - almost anything is do-able

question is: do you it you really need to do it - as it is also avoidable

i'm looking at building a new gun or developing one. I am looking for trigger response and dsg just shortens the reset time.

Then whatever you decide that £45 box is a decent option

Personally - we all have dreams of building a bespoke gun from scratch that is a hose machine....

Two things:

1 - building a gun from scratch means a lot of potential headache issues to overcome

Often an easier/wiser consideration is to take a decent base gun - even a faulty one needing TLC

than try to assemble a load of parts that "may" not be 101% fully compatible without "some" modification/adjustment

From spending £100's and finding that rail system doesn't like that receiver, feeding issues coz the nozzle is a smidge too long, that STFU pistol grip produces an awful motor angle and sounds like a tin of wasps when firing etc... etc... etc....

So you would have to be very f**king fortunate not to run into "some" issues

and if you did you would need to know or learn the hard way about resolving a number of "possible" issues you never imagined

I mean it could go without a hitch but in reality - even experienced techs can run into issues on a "from scratch" build

So perhaps consider using a decent base gun maybe ????

2 - The faster it runs - the quicker it breaks is a fairly decent rule of thumb in a like for like world

(don't use a slow pile of crap china slap together gun out of the box to a snappy precise custom build)

What you will learn most likely is a general rule of thumb for many is that twenties is plenty

Sure you can go faster - but it most likely will crap out/fail quicker is what I mean

I don't give a f**k what anybody says - like for like the faster you go the probability of failure increases

The trick is to find an acceptable balance, which up to around mid 20's is about a good sensible limit UK wise

Finally it isn't how fast the gun shoots it is usually how skilled the person using it is

sure a good gun helps - but it is the player not the gun's performance that usually wins the game

I don't care tbh, I'm just trying to give you a little bit of advice that's all - I was like many on here the exact same

Drop a SHS DSG sector in ya gun - it isn't a lot of work tbh - just it will likely fail quicker if you go too nutz

I'd lower your dream to a more realistic/practical goal and try not to run before you can walk so to speak

When I saw DSG gearbox I thought I had clicked on one of my car forums for a minute ! ?

I recently finished my first scratch built gun with 12:1 shs gears.  I wanted super response/ROF and that gives plenty with a high torque motor.

I was adamant I wanted to run it on 11.1 but my high caps were tying their springs in knots trying to keep up,  and I was still having feeding issues on a 7.4V until I got some decent mid caps and fitted a delayer chip. Its still like a bloody hose pipe on 7.4V.  

I would listen to what sitting duck is saying.   He was very helpful while I was asking questions on my build and if I had listened to him sooner I could have saved some money and time.

The best thing I did for response was a hair trigger mod, speed trigger and mosfet.  It's not technically response in the cycle but the gun reacts much quicker to finger movement.

If I had the knowledge I have now when I started my full rebuild  I would do the above, replace the wiring and connectors, hi torque motor and dean's/ xt60 and run 11.1v.  Maybe bump up to 16:1 gears and a delayer chip.

Leave DSG till you have enough experience to iron out all the creases yourself.
