Yeah, not good…
@Wombat what sort of failure did the gearbox have? 
I was seriously considering ordering one of these tonight… think I’ll take BME’s advice and wait to see the outcome of this.

Sounds like piston ladder

mm me too, I’ll be waiting now see how gti and Wombat go. I was kinda thinking bit hmm I dunno when Wombat mentioned the odd size main spring.
Of course I could just throw that in the bin and fit a decent V2 alloy box I have sitting on the shelf collecting dust.

Same! Get the facuck outta my head! 
HaHa…!!
"Whats the chorus, boys and girls…??
It wouldn’t be Gel, if you didn’t have to f@%k with it…!!"
If nothing else, $160 gets you a pretty cheap shell.
put a decent gearbox in it with a few upgraded parts, and your good to go.
Mind you, the LDT box might appeal to others now, if you need to replace the JM gearbox…
The metal gearbox and gears in the LDT were pretty reasonable…lets just see what performance we can squeeze out of it…
Yet the most reliable blasters are the $100 CYMA/Jund M4’s with nylon gearbox and gear that run forever with M100 springs. Add metal gears, good piston and volumetric matched barrel and 300fps all day

@BME the next time we’re occupying the same space and time we’re going to try out the longer barrel from my MP5 in your K and see if we can rule out short barrel length as a cause for the low FPS. It also has an o ring in the t piece, so we’ll see if that helps. 
That’s a known 260FPS unit, your gearbox and airseal should be better than mine, so I’d expect to see at least the same FPS if not higher.
It’s all about logical elimination of possible issues until we get it right.

im very much hoping iHobby just swap it. I really want this gat. It feels very nice … and i bought 2 extra mags. whats worse is my first attempt to shoot it was at wifes car as she and the boy pulled in … but noooo… im left looking like a d$%k with my 14yo laughing at me.

Maybe, with some luck, these were the 2 failures, out of a batch of 200….
Murphy seems to like finding us…

The unfortunate reality of a short barrel is the gel only has a small distance/time to be accelerated before it is on its way over there.
Mate and I messed around with a 160mm barrel blaster that with an m100 would send gels over there at 330fps, very consistently… then used an m110 spring to see what we could get out of it… and it only got to 340fps and consistency was a bit out the window, so was accuracy. We also tried an m120, which got the same result.
We even thought the springs may have been mislabeled and tried them in longer blasters which did get the rated fps.
Shorter barrels just have only so much potential was our ruling in it end. Fun to try and get it maxed out though!

So the law of diminishing returns… huge spring upscaling gives minimal FPS improvement.
Not worth putting all that strain on your gearing then, by the sound of it.

Tests only showed a 10fps gain. Was using the stock spring. Looks like it can’t handle semi rapid fire. Was semi only game, chronoed by field at 180 fps and firing 3 rounds on contact. I bet it has metal gears and nylon ladder.
That’s why I go big bore barrels on shorties 7.5mm and 7.6mm ID.
Have you tried that. I remember you mentioned in the past you only run 7.3mm ID on shorties.
I dunno they just work better for me, may be some other factors involved, what they are I’m confused with female interns at the moment 
I am a 7.5mm barrel guy. Nearly all my blasters are 7.5mm. I never tried a 7.6mm but that’s more down to just never came across one that wasn’t stupid expensive.
I remember seeing primal barrels that were around $50, I just couldn’t justify it.
Only blaster I have a tighter barrel on is my vectors, and a couple longer ones have 7.4mm as an experiment and worked and never changed as they worked well.
I am due to trial a few barrels on my shorty j9 with MK H92, as I got it built then never got to finish tuning barrel length.
Might be a good experiment!
Dont take the interns… in turns…!!
you’ll get a bad rep, and they wont come around, any more…!!
I dunno I got 8 to choose from. One I was quite taken with, and she’s from Iraq. Holy smokes first Iraqi I’ve met and and I was a blabbering mess. All of a sudden I feel sick and need operating on Wow it was a good night
Hmmm, lets look at the symptoms…
Sweating, increased pulse, uncontrollable urges, high blood pressure…
It sounds like she needs to give you…
An emergency strapadictome…!!
This is shitpit material…
Oh right I probly can’t remember right what you said or took out of context.
I just know the XYL ARP9 I have clocks in 7.6mm ID barrel. Not sure which version it is maybe v2 v3 era. That good all I did is change the piston for full metal ladder, O ring and put on a hop up. Real good otb blaster Also the first APS pistol, But need the harder gels like AKA’s. Those were stated as 7.5mm ID barrels but if you accurately measure them they are 7.6mm which changed with the later versions of each.
