    JG stock gearbox, but chrome cylinder because it was nice and shiny when i first put it in last year.
    i also rewired it with a JG type mosfet. didn't video it because it was getting late and my son needed it for a game the next day.

    Do I need to add the same amount of spacers or will it just depend on my gun?

    depends on the piston/head and cylinder head cushion thickness. i've had some AOE adjusted perfect with just one nylon spacer between the piston and piston head. on some, i had to shave down the rubber washer. but most of the time, the rubber washer thickness was just right.

    What is the principle behind AOE adjustment anyway?

    The principle is that it stops your sector gear annihilating your piston...

    without correcting AOE (not correcting the contact angle between the piston pickup tooth and sector gear), the force of the spring and the opposite force of the sector gear will push the pickup tooth upwards instead of the proper direction towards the spring. sometimes, the first sector gear tooth will slip under the piston pickup tooth. you can see the indentation on poly pistons. for weaker pistons, the pickup tooth end will fail/crack.

    AOE is not as critical on lower fps/spring ratings. there is also an advantage of AOE correction using rubber washer on the cylinder head instead of nylon washers on the piston. it reduces the impact stress on the gearbox. there are some that prefer to use nylon spacers between the piston head and body.

    Thanks for explaining it thoroughly alex!:) ive been cutting out circles off my mouse pad (cheaper solution compared to sorbo washers) and super glued them on the cylinder head, but never really understood what AOE was for.

    I'll change it when it's worn out. I didnt have to do anything to the piston body coz its an shs 14 tooth piston. Well, thanks for the feedback alex!
