I built a 10 liter rocket and when it launched, it immediately pitched over and a tree peeled the fins off. I need help for a rocket launcher stabalizer.

Either the nozzle is too small for the volume of the rocket, or the pressure is too low for the size of the rocket. If you are at maximum pressure your rocket can take, then you need a launch tube or an external guide. You can make an external guide out of metal tubing or pipes or even out of wood. The way you make it is really not that critical, as long as it doesn't pinch the rocket. You can enhance it when you have a working design by adding teflon tape to the surfaces that touch the rocket. Teflon will make it nearly frictionless.chemdude wrote:I built a 10 liter rocket and when it launched, it immediately pitched over and a tree peeled the fins off.
