Gg Gearbox Lock-up With 13.1 Upgrade

? Madbull barrel

 Don't worry man, only the chamber comes from madbull? 

The inner barrel is one from Aliexpress and its seems that serves quite good. I buyed two, short and long and they're stunning. I mean, they are made from good quality material and they came as the Madbull does (inside a tube and etc).

Are you definitely testing FPS with 0.2s?

Yes, I used to play with 0.25g with aeg and pistols but for chrono I burn a lot of 0.20g.

So definetly I will put sorbo pad inside. 

I was thinking the same about the spring like... Huh? Softer spring means more rps so.. PME is returning ?.

Shoud I go safe and short stroke 1-2 teeth?

I think I might need a sort lot of different spings just in case. I don't know how "strong" is the G&G original ones. 

Im learning a lot with this ?

Hah cool, I still wouldn’t run a 6.01 on anything other than a pistol.

6.03 or 6.05 for an AEG.

With 6.01 straightness is very important and it doesn’t take much dirt or crap BBs for things to go wrong when your barrel is longer than a pistol AND your pumping 25 BBs down  there EVERY SECOND!

Personally if I were you I would;

Buy a new M100 and M90 from a known brand.

Step down to 7.4V or get a slower motor - I can’t believe the motor you have is 18K, it doesn’t add up, you must have a good one!?

Another option for you is;

SS what you have by 3 teeth, that should drop you about 45 FPS.

Put your sorbo pad in, that’ll drop another 5 FPS.

SS BY 2 TEETH FIRST AND TEST - YOU CAN TAKE ANOTHER TOOTH OFF, BUT YOU CANNOT PUT IT BACK ON!

Stil a good practice to buy a couple of known springs for your reference.

In must to do list ?.

I attach some image from the g&g 18k motor. It was already inside!! Anyway I will use it until the very end.. Then a m140 ?.

I found this "sorbo pads" on my chinese dealer in my country. As soon as I saw the size I thought, c'mon, take it.

It perfectly fit inside the cylinder. The only not expected size is the height. Arround 3mm. It seems gtg isn't it?

Also the material doesn't seem to mesh so easly. Is hard enough to resist but wouble enough for absorb the impact I think.

I tested this inside a shitty cylinder with shitty piston and doesn't seem bad at all. 

I will give it a try. ?
