just a initial review, chucked in a G&G raider 2 to see what its like.
for what your getting for the price looks pretty good compression is good got the same power out of the same g&g spring.
first issue the motor wiring was too short just cut and soldered a bit on.
second selector was stiff and no full auto will look if its missing the micro switch.
third quite noisy compared to stock but again just chucked in will update when i open her up

Quick and easy install. No full auto. My G&G 13.5″ sits now at only 260FPS

I bought this ZC v2 gearbox to replace one in a M4 with a split casing.
I have not been able to get the fps above 224, I have tried to make sure the compression is good, I have increased the spring rating but 224 fps is as high as I can get. I had to replace the tappet plate as the nozzle end was distorted and didn’t engage the nozzle properly.
The mosfet is good, the gears look strong, the piston, piston head and cylinder head are all good, but the performance is disappointing.
I expected to achieve 280-300 fps on .25g BB’s.
But at this point seems unattainable with this gearbox, disappointing.

Used this as a replacement for my standard G&P M4 gearbox.
Very impressed with the performance increase over the standard. Fitt’s a little tight in the gun, had to shave the box a very small amount to fit the small cross-pin. Also it’s tight up against the hop unit but can still get everything together with a little extra force.
Chronoed at 330 – 340 fps out of the box, standard G&P hop and barrel. Full auto is 2000 rpm using a 11.1 lipo. Its now pretty accurate out to 40 metres! Very happy. will be upgrading the barrel and hop very soon :)

Works well, good quality, metal spring guide is nice, id say its better than most standard boxes
