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...

So make it qty 2 400mah and 2 900mah. Sound okay? Let me know how to reimburse you. Batteries received and will be waiting for you at Thunda ;-) we can just sort something out when you are here (I do like American bourbon... just saying lol) Sent from my iPhone using Tapatalk Ha!

All the best Ari

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

Another option is the F22 with about 3.1 seconds of thrust https://ausrocketry.com.au/motors/reloadable/hobbyline/hobbyline-29mm/f22-7j.html Here’s the link to the G33 https://ausrocketry.com.au/143g33-9a-m.html Both aren’t listed in stock, might want to check with Blake, it’s posible they are actua...

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.

Looks like the new Raven 4 is now available.

Blake is unabe to source you one? I do have an untouched 98 mm fibreglass nosecone lying around at home I was planning to use for a future project... https://ausrocketry.com.au/nosecones/fibreglass-carbon-fibre-nosecones/98mm-g12-fw-fibreglass-5-1-vk-nosecone.html Best to actually call Blake, the i...

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...

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?

Thanks for sharing the pics, looks like a great day. 6 cert attempt has to be some sort of record for a single day event.

Congrats all round.

Ok so that’s about 30 yeah? Are you going to be selling them?

Nice one. Need to get my act together and do some 3D printing.

How about http://www.aircommandrockets.com/dark_shadow_3.htm

You could do something similar to aircommander water rockets, He does a lot of non pyro deployment.

Here is a good example: http://www.aircommandrockets.com/dark_shadow_3.htm
