Re: Newbie: Make your own rocket from scratch or buy a kit?

If you do want to design your own rocket then I recommend you get a copy of Open Rocket. It will tell you a lot about how your rocket will perform, you can share your design for others to review here as well. One other consideration is where you are launching, if it’s with a club they will have laun...

Re: Importance of an inner motor tube for high powered rocketry

If you don’t use a motor tube, keep in mind that your CR inner diameter will need to be smaller than standard.

Re: F10 Rocket Motor

As Brad said this is a unusual motor, with a very low average thrust you need to look carefully at the velocity of the rocket as it leaves the rod/rail. The rocket can easily be too heavy for the motor resulting in stability issues.

Re: Joe Turner's 38mm Scratch-Build

ok I think that final Z fold is not a good idea. If I needed to reduce the length I would do it after step 5, but I see they have an option to do that last but I don’t like how they’ve done it either. With the extra fold down internally placed it is basically trying to push open chute. You also want...

Re: 13th January 2019 Launch

Sorry your flight didn’t work out Joe.

Is that the chute in a Z shape? I’ve not seen anyone fold like that before. How high was main deployment?
