Hey bro, look at this babe
just installed with LDX gearbox, what an excellent semi-auto mode!
Ridiculous!
You handsome guy starts to ruin the regulation, too, eh?
We boycott the full metal, boycott you!
Anyone who uses the metal gearbox will screw up!
Idiot...
Wow, LDX gets on sale discount!
I gonna order one
Play Gels~
The internationally famous charity company “LDT”
just released their LDX full metal ver.2 gearbox
and it is a big bomb that causes a hot discussion from two sides of the gel fans
To be honest, I wasn’t interested in it too much at first because I’m not the guy that pursue extremely prefect
The nylon gearbox is pretty good enough for me
so the metal one doesn’t attract me that much
However, very interesting, only a few days after LDX was released
its sales volume goes over than a thousand
Seems like the majority of silent men choose to give it a try eventually
LDX has two versions: Basic and Advanced
and their main differences are in between the mechanic trigger and the electric fire control
For me, the best is the best
so I choose the advanced version directly
LDX is the first ver.2 gearbox with full metal body and completed MOSFET chip control
The “ADVANCED” logo on the box shows it VIP identity
On the lower-left corner
it says “only for gel blaster”
For those who want to try something, you’d better give up your dangerous idea
There is a manual of MOSFET electric fire control starting guide
which introduces the functions and usages of the MOSFET in detail
There is a feeding nozzle in the box to fit the receiver
If you want to upgrade a new gearset
use the magnet provided in the box and assemble it on the new gear
The gearbox can be separated into the upper and the lower part
Lead-zinc alloy body assembled by two types of allen screws
There is no inserted nut for it
but due to the metal body, no worry about the sliding problem
The black upper part and the red lower part are put together by a designed locking pin
Be advised
the teeth and the tappet plate are in the released position now
so rotate the gear to the teeth side to combine two parts
The outer body of the gearbox is smooth, no wire outside the gearbox
The plug is the Small Tamiya type
Black upper part a metal cylinder with heat dissipation texture
On the top, there is a standard Jiqu blowback track
which could fit in Jiqu’s own EBB accessories
The metal QD spring guide, #6 allen key is needed for disassembly
but there is no horizontal bearing here, a little pity
Spring diameter: 1.2mm, 10mm in gap
155mm in total length, a mainstream size
On the front, the mag connector goes with a QD chassis
It has two types of contact plates
which should be fit into LDT’s own 416 and MP5 magazine
The wire connected to the mag is thin and the weld isn’t good enough
It just broke off after a few times of disassembly
The manufacture says it will be improved in next round release
Except for the LDX logo on the lower part
there is also an independent product number on it, the red lacquer looks pretty
It doesn’t help with the internal function
but who doesn’t want their baby looks beautiful?
Six 8mm bearings on two sides
and this version contains the balls between the bearing and the holder
which guarantees its stability and efficiency
A small hole is reserved for the ambidextrous selector switch
so it will also fit well on MK17
Due to the electric fire control instead of the mechanic button
there is no friction when pulling the selector
The trigger is made by metal, pulling is fine
you can hear a little “click” when pulling it
As the first full metal gearbox for gel blaster
LDX’s weight goes over 520g
which is a time heavier than the nylon one
Lead-zinc alloy outer body, the thinnest part is more than 2mm
Some people will argue with the sturdiness of this material
but the high standard alloy is absolutely better than the nylon
The separated structure let inside checking (gears, teeth, and tappet plate) become easy
which is also good for gears adjustment
Another big advantage of the metal body is that
the shape change of the body is puny compared with the nylon body
More stability in high-speed firing, and a longer life span
However, even the gearbox can be separated into two parts
but due to the mortise locking structure, it cannot be separated like a scissor
Open the gearbox, you can see the metal piston with 14 teeth
On the top of the cylinder, there is a slot for EBB accessories
Three metal gears have been pre-adjusted by the manufacture
18:1 in ratio, a common gearset for now
Different from the basic version
There is no complicated lever function for the trigger
instead, there is the MOSFET control designed by LDT and BR cooperatively
This set of MOSFET chip can be bought independently
but for me who has a poor handj*b
the full assembled LDX will be a better choice
You can see a magnet on the gear cooperating with the Hall Sensor of the MOSFET
which is used to sense the position of the gear and the teeth, help stop the motor
However, for this high-level gearbox
it’s a pity that the higher ratio steel gears aren’t used
It may due to the stability consideration for a quantity production gearbox
The gearbox is standard AEG size, which can fit into most of the standard AR receivers
LDX is able to absorb 7.4~16v electricity
and no specific motor requirements
Very easy to assemble the gearbox
if you have hands then you can make it
good for my poor handj*b
Testing after complete assembly, the muzzle velocity is stable around 80m/s
But pay attention, frequently stop of the motor when choosing semi-auto
will lead to extra heat producing
There are lots of other functions of this MOSFET
such as pre-loading when inserting the mag, 3-rnd burst, 4-rnd burst, even 5-rnd burst
and my favourite double-action semi-auto
Pulling and releasing the trigger will give a shot respectively
which makes a high rate of fire on semi-auto mode
The performance of MOSFET is way better than the mechanism
The piston will be in the right position every single shot
and its stability on semi-auto mode is not reachable for the mechanism
The stopping function works excellently on this gearbox
and it sounds fantastic
As many of you might know the video “no full auto in buildings”
The gun that the guy uses is coming with the MOSFET, which gives him a crazy semi-auto fire
Since the first magazine feeding blaster, separated body, ver.2 gearbox
then the P1
Schrödinger's theory of “ruin the regulation” is still developing
In fact, lead-zinc alloy gearbox isn’t new stuff in airsoft
and some ancestor players don’t really like it
If it isn’t for extremely upgrading
the nylon gearbox is already satisfactory for most of the upgradings under the legitimate red line
Thus, obviously
LDX won’t let you break through the limit of the gel blaster
But as new volume production of full metal gearbox
LDX, especially the advanced one with MOSFET
It provides a decent, stable platform for those pro-players who want to upgrade their babies
And for those newbies who just want a gearbox, LDX is another new solution with full assembly
At least its metal teeth won’t have the gear broken problems
which makes a better performance for them
Just as the words on LDX’s box: NEW GENERATION
It could be the start of a brand new era, who knows?
If you have any opinion or suggestion to this new gearbox
