After some thought about the next move I actually decided to make the nose cone next. The reason is that I want to work out the weight balance which is going to affect a bunch of decisions I’ll make. I decided that the best way to do the nose this time is to do a 3D printed one since it’s shape is s...

Camera shroud is a good idea. I’ve thought about creating a replacement case or at least bottom that fits directly to the rocket to minimise size / drag, but that’s beyond my cad skills. Yours is pretty close, hows it for strength?

Nice vid btw.

Thanks everyone who help make it happen.

Eek Well I guess you know where the most likely point of failure will be.
Good luck with that, will certainly be an interesting flight

How fast will it go? And related question, how are you protecting the nose/LE against erosion? I’m concerned about that stability at burnout of the sustainer, N5800 is notorious for trashing rockets at that point. Clipped delta fins are good in my book (gets more fin material out in clean air), but ...

Some more on black arrow

Wow, very nice looking build. I shall watch with interest.

My standard question for such a flight, can you please post the stability over time graph?

Welcome to the forums DB, great time to be getting into aerospace

I’ve just used OR, need to make sure you enter all the parameters correctly but don’t play with the CD unless you are tweaking it based on measured decent rates.

Your best bet would be to try and contact AMRS directly. https://rocketry.org.au/contact-amrs/ Also the person certifying needs to have level 2 certification, but I think there will need to be other issues sorted out with the launch to make sure you are within AMRS rules as well as NT Gov, local gov...

Very nice indeed

Anyone got recommendations on 3D filament?

Either locally in BRisbane or an Australian online seller.

Looking for reasonable prices for reasonable quality.

Where’s Stewart when you need him.

Anyway, big question is it a compliant transmitter, cause you can get yourself into a lot of bother with regulators. In had with that would be what frequency, power, licensing etc.
