I've pulled apart a Hornet and the thing makes no sense. The blast chambers don't have a mechanism to release the air, the blast buttons seem to actually release pressure, and I don't have any idea what the hell the piston thing does. I believe the Big Salvo and Spider-Man Dart Tag Guns use similar principles.

If any mechanically-minded Nerfer has determined how the blast chambers, piston thingy, and blast button function, please enlighten us!

Hornet tanks and some others actually fire when the pressure in the tubes behind them is released, which is what the piston and blast button do. The piston like device functions like a blast button. As you pull the trigger, the head of the piston moves back, which causes one tank to release pressure to the atmosphere like a blast button would, which fires the tank. The blast buttons are connected to all the tanks, so when they are pressed all the tanks fire

...Just a lot smaller.

There's an animated version of it somewhere which I can't find right now. Someone else will probably find it.


All the tanks that I've seen work like coax.swf where the piston seals against the outlet to the barrel, and air enters the chamber from around the piston, and the chamber goes "around" the outlet to the barrel.

The animated version is at the bottom of the page; just scroll down and you'll see it. Also I was gonna ask about this in my own thread, but I feel its appropriate here. I have a bunch of hornet tanks. If I were to do a tank extension to them would it screw up the way it fires?
