If your talking about an airsoft gun, then it all depends. Your gun must first be capable of having a adjustable hop up, then if it does, it should be a little wheel or a little nub either along the barrel on in the chamber.
there is no hop-up system on a Crosman C-11.
you don't. uhc super 9 don't have it and the uhc super 9 pro have fixed non-adjustable hop up.
Best left to a trained professional.
it is like a hop up system but you can change the bb's left and right trajectory ans well as the up and down trajectory. It also has two contact points shaped like a V so that the shots will not go crazy, each shot will be the exact same as the last (unless you adjust the hop up)
because your bbs are too light, buy 0.2g instead of 0.12g, also adjust the hop -up
Yes this gun has great accuracy if you adjust it and set hop up right

The p50 does not have hop up.
Your hop-up is on way to much. If it is not adjustable, heavier bb's should go straighter. If most guns it is adjustable, so you just need to tone it down. The most common place to adjust the hop-up in an AEG is be hind the bot cover. To expose it just pull back on the charging handle. Sniper rifles often have a small hole on the bottom of the fore grip in which there is a small screw, which when turned with an allen wrench adjusts the hop-up. In gas blowback pistols, to adjust the hop-up you often need to take the whole upper receiver off, and then turn a small wheel near where the bb is loaded into the inner barrel. If it is not in one of those places, check the instruction manual. Usually, turning the hop up clockwise will make the bb fly up more, and counter clock wise will make it fly up less.
On the top of the gun under the handle is a bar that has a end that flips to the side. Pull it to the side, pull back, and hold it there. When you pull it back a slide on the side should open, showing a white cylinder. Turn the cylinder up to decrease or down to increase hop up.
hip hop rap is when you rhyme hip hop is more broad then that.
Good... usually. Without hop-up, BBs tend to fall after ~15-25ft. However, be sure to get an adjustable hop-up, or you can end up with BBs going straight up after ~15-25ft! Learning how to fine-tune a hop-up is a crucial skill if accuracy is important.
