2 successful launches of my 2 staged Estes Mongoose rocket

The day for the launch had arrived. The weather was mild, the winds were calm and the level of sunlight was just perfect. The recovery system failed to deploy on my first launch due to what I suspect to be my mistake in packing the wadding, parachute and cord in the night before the launch. Presumably this approach had allowed the stuff to expand and get stuck against the rocket body itself. Thankfully though the rocket landed unscratched thanks to the thick layer of green grass on this field.
The best part of the launch is having the company of my good buddy who also filmed the launch and helped track where the parts went afterwards.

Awesome video! Thanks for posting. I am just starting to experiment with multiple stages. This answered a lot of questions. You did great at explaining your thinking through the process.

So in order to set up the multi stage launch you just tape them together and they work? Is that what I understand?

I just got one of those and I was hoping that they could launch twice

I just built one but I’m wondering did you only use one starter for the rocket or did you hook a starter to both of the stages ?
@BrianSu
@BrianSu 2 года назад
the 2nd stage is started by the 1st you only need the igniter on the 1st stage you can only use black powder engines for the 2nd stage, normal Estes ones. Make sure your 1st stage has 0 delay.

If the mongoose has a plastic fin can, suggest streamers or using a small chute, smaller than Estes 12 inch or cut a spill hole, or tape the strings to maker it smaller Otherwise too many 2 stage rockets are lost.

My engines fall out on stage II, then chutes don't deploy. Thats what I think at least.
@BrianSu
@BrianSu 4 года назад
wrap a few layers of tape around them to create more friction with the rocket's body.
