Motor Change

[Mcdan360]

Haha I didnt realise you were the same user that messaged me the other day... thanks for the vidoes again though. Instead of selling the Krytac i have decided to keep it and spend a little more money. I have just purchased an ASG infinity 30k motor, a gate titan and r-hop patch.

Howdy folks!

Was searching around Google for some knowledge (I don't know much about internals at all) and this thread seemed the best.

So here is the situation:

I'm wanting a Krytac for the collection. I like the Alpha SDP.

I'm in the UK but want to beef it up a bit. I believe it fires around 280fps out of the box here with .20g.

Firstly, was thinking of swapping the 20 motor for a high torque SHS.

Then using a 11.1 LiPo:

https://www.ebay.co.uk/itm/232139712267

Then a company who sells the gun recommended a Slong18:1 gear set (CNC parts), all steel cylinder and a Slong piston.

I asked them if we could put in a 150 spring to get some ridiculous fps but they point blank refused, saying the 150 spring needs 35A to be pulled and that the battery I showed only provides 20A constant, so.... 

Sadly I'm no electrician so don't understand it much.

Are they speaking the truth? The battery says 20-40... others have said they get constant 30 on 10 second discharges - I doubt I'd be using the gun in full auto for 10 second bursts! Never in fact.

Any experts on here can give me some advice? The gun is not intended for CQB games ever, just for awesome fun at home.

Thanks.

An M150 would make the gun illegal in the UK, not just hot, but ILLEGAL.... don't do it!
You will be fine on the standard motor with an 11.1v, no point changing it. Mine shot at around 330fps out the box and with hop added the fps went up slightly. 
Don't worry about mods until you have tried the standard gun.... they really need very little doing to them.

Oh really? Don't some sniper rifles have 150 springs? I mean, it seems many are for sale in the UK (150 springs)

Thanks.

Have you looked at the rules regarding airsoft in the UK at all?

Single action rifles (like sniper rifles) are allowed upto 2.5j legally before it is classed as an air rifle, most sites however only allow upto 2.32j
AEGs are only allowed upto 1.3j legally before they are classed as a FIREARM although most sites only allow upto 1.14j

Converting an AEG to a firearm is a serious offence and carries a mandatory sentence of 5yrs iirc

The UK lol..... so many silly laws!

But thanks anyway... I'll look into it.

I'd be ok with being shot once by a bolt action at that fps that was shooting outside of it's minimum engagement distance, but I'd be proper miffed at anyone who thought it ok to fire a 25rps gun full auto into me at that energy level at any range!

Maximum Velocity Limits


BB Weight


Single/Semi-Auto (2.5 Joules)


Full-Auto (1.3 Joules)

0.18 grams


547 fps


394 fps


0.20 grams


519 fps


374 fps


0.25 grams


464 fps


334 fps


0.30 grams


423 fps


305 fps


0.35 grams


392 fps


283 fps


0.40 grams


367 fps


265 fps

So this chart basically says (despite formatting error here)

That an AEG firing .20g BBs over 374fps is a "lethal" weapon

I'm going to go out on a limb here and guess that MANY airsoft guns shoot over 400fps with .20g BBs

So they are all LETHAL weapons now?

I'd be ok with being shot once by a bolt action at that fps that was shooting outside of it's minimum engagement distance, but I'd be proper miffed at anyone who thought it ok to fire a 25rps gun full auto into me at that energy level at any range!

and if it was never shot at (or intended to be shot at) a person or animal...

Anyway.. you didn't write these laws.

And an AIR RIFLE (which no UKARA defense is needed for) is allowed to fire 16 Joules in the UK.

Just nonsense.

So... LAW ASIDE... can we keep the discussion "purely hypothetical" and just discuss motors and gears and currents etc!

Last I heard that was still legal, to DISCUSS ideas.

Thanks!

ok so you'd be happy someone shooting you with a 16j air rifle?  I think not.
If you are not going to use it for airsoft, why not just get an air rifle? and "lethality" is not "fatal", different meanings especially in law! ? 

Back on topic (soz)
I ran a Krytac with an M150 spring, 11.1v LiPo and the USA spec Krytac motor (UK is 20k, USA is 30k) and a Orga WBB, it shot at roughly 345fps, the gun ran, but it would have eaten itself if I kept it that way.

ICS do the same with their AEG's.We get the Turbo 2500 motor instead of the Turbo 3000..

The reason for the motor change is to minimise motor over spin that courses 2 bbs being fired from 1 pull of the trigger on sub 400 fps rifles

What is an Orga WBB?

Thanks.
