please can you make a toutorial on how to make wings?

[gabrielrochasantana]

In the staging mechanism,is there a hole in the booster stage to suply the upper stage with air?HOw much pressure do you got it there and how much it can hold?250psi?

[antigravityresearch]

Yes, there is hole at the top of the booster, with a closed end PVC tube in it. The tube has two tiny pinholes in it to fill the upper stage with. The pressure from the lower stage expands the tube which presses out inside the upper stage nozzle and holds onto the upper stage. On the AntiGravity 2-stage rockets, it normally runs at up to 80 or 90 psi. But it can work well at 200 or 300 psi if you have reinforced bottles. KS.

What kind of mechanism sets the stages apart?

[antigravityresearch]

There is a tiny pvc closed tube at the top of the booster stage.

It has two pinholes in it for the upper stage to fill through.

The pvc tube expands when the rocket is being filled and holds on to the inside of the upper stage nozzle. When the booster is empty the pressure in the upper stage slightly collapses the pvc tube and pushes it out.

You can get one from the AntiGravity Web Store, or get an entire 2-stage rocket.
