Im about to rewire my gun and it didnt have a fuse on it what fuse should I get?

If you wire a fuse back in, get a 20-25amp fuse. If you can, try to get a self resetting fuse.

I herd somwhere that glass fuses are bad is this true?

Glass fuses are bad because they cause lots of resistance in the electrical system. Resettable fuses are wired directly into the wires, and don't cause NEARLY as much resistance as a normal glass fuse.

Do you reccomend i get a fuse?

I have this but in a 30w.

That'll work. Personally, I don't have fuses in my guns.

What are the advantages or disadvantages

Fuses protect your battery, motor, and mosfet (if you have one). If something goes wrong, resistance will build up. The resistance causes heat and that heat is what causes damage. It protects from shorts in the wires, jams in the gears or motor, mosfet failures, stuff like that.

However, glass tube fuses cause terrible amounts of resistance, kind of ironic, but that's what happens. Blade fuses, like what you linked are better, but they still cause resistance. The best kind of fuses are the resettable kind, because you can wire them straight into the wire system. They have the lowest amount of resistance out of the other kinds of fuses and reset, so you don't need to replace them. But they are still a sort of crutch. If they pop, that usually means something is wrong, and you shouldn't keep using the gun when they reset. Another problem is that high output systems can pop even the strongest of fuses simply because of the kind of power that is running through the system.

That's the reason I don't run fuses myself. I know when to stop pulling the trigger, when I hear something go wrong, feel it stop working, I stop pulling the trigger. Simple as that. Nothing has ever been damaged by NOT pulling the trigger, stuff is only hurt by holding down the trigger.

A general rule of thumb is 20Amp for stock guns, 25 for slightly upgraded guns, 30 for highly upgraded guns, anything higher and the motor is more likely to burn out before fuse pops. Higher than 30 is usually to protect specialty batteries or very expensive electrical systems and mosfets.

ok thanks
