Phew - you got the M140

THIS is a decent-ish motaaaaaaaaaa

 

it is on par with a SHS HT there abouts

not too insane - not mega amp draw

and doesn't run very very warm, that is burns out quick

(like the insanely fast M160 BD)

 

The 140 is a torquey motor with grunt but not insane shit

 

the 160 is like the SHS High Speed - quick as fuck

but will run very very warm/hot and drain battery quickly

plus it runs so warm/hot, the 160 will heat up lots when going nutz

and bearings in the can will crap out, end bell gets hot & bearing loosens

 

basically the 160 will just tear itself apart if you start to cane it

& what you will be left with is just the neodym magnets

& unlikely to use the say 14tpa armature much from the 40k+ motaaa

 

the 140 is probably about a 17/18tpa likely a 25k to 28k

 

it is a cheap motaaa, with them tabs at the end

rather than the SHS/G&G lock ring type

D pinon - was a slightly bit different to SHS pinion

seems to mesh slightly better with Cyma std pinions

 

Now they might have changed spec slightly over the years

(likely)

But If anybody remembers Airsoft Peak & TinyWind (snigger)

in Hong Kong knocking these out really cheap with offers/vouchers

 

I bought a couple of 140's and half a dozen 160's

(plus a few shit m120 ferrite ones - yeah avoid)

wish i bought all m140's and avoided the 160's & 120's

 

imho - the 140 is the best one in the Big Dragon range

so you made a wise choice I reckon with a balanced motor as they say

 

The M120 has ferrite magnets & a blue motor tower

The M140 has neodym magnets & a red motor tower

The M160 has neodym magnets & a gold motor tower

 

D type pinion that meshes nicely or slightly better with some other bevels like Cyma stock bevels I found

 

avoid the M120 = G&P clone

the 140 & 160 are about same price

go with m140 over the 160 is you want it to last properly

 

A SHS HT will be easier to service though

but the M140 type you could drop a diode across it to reduce contact arcing without needing a mosfet straight away

 

so horses for courses as they say

m140 is a good motor upgrade for stock gun without needing to rip it all out and rewire with mosfet but use a diode

 

 

 

DON'T INSTALL A DIODE IN A G&G OR SHS !!!!

it will short out - but is safe in a TAB type motor

and does reduce arcing/spikes

Could be platinum.

 

Or even mithril.

 

Hmm, it's actually pretty darn magnetic (moves it surreptitiously away from my laptop).  That's surprising, I took a gamble on it as a ~£20 purchase from Ali Express just to be a bit contrarian.

 

I guess the proof will be in the piston pulling.

it is alright - it has some grunt

perhaps not quite as quick as a SHS HT @ 30k tops

but deffo 25k maybe a bit more

 

you could just slap that in a cheapo Cyma m4

maybe a diode and just run it for some added zest on the cheap

and it will serve you well, last a good while

and when all said & done you can gut it and use the neodym magnets

for another motor rebuild when it all croaks

 

but won't tear itself to bits like the M160 does whilst draining your battery like a gold digging GF
