Re: Launch of OZ AREA 51

Great video Ari.

Pleased you made me a co-star! (even if you were just filming top of my hat as I looked to the sky).

Re: L2 build

Thanks for the offer Blake I'd appreciate that. I've been doing some practice on leftover tubes and I reckon I'm getting there, but not quite ready for the real thing yet. I'm not working at the moment, but I do have a few commitments. When do you think you would be doing it? Monday or Tuesday after...

Re: L2 build

I know nothing about these microbubbles or nanofarts or whatever. This sounds a bit more sophisticated that just slopping a bit of Taubmans on.

Re: L2 build

Good question Lister. I just bought some from Bunnings. It is a pretty coarse weave, and left a pronounced weave finish which I was wondering what to do with as far as filling.

If you have any recommendations....

Re: L2 build

Thanks for the feedback everyone. After some discussion about whether I might get interference between my altimeter and GPS, it seems that whilst interference is possible, I can probably get it to work with them both in the same bay. I will need to test this on the ground but as the BRB has not arri...

Re: Interference between devices

Thanks for the feedback guys. It seems that the consensus is that there could be a risk of interference, though there is plenty of experience that indicates I could get away with it. I don't have the BRB unit yet, so I can't test yetr, and the build must proceed, so I'm placing an each-way bet. I'm ...

Re: L2 build

So a slight problem has emerged. Even with the smallest motor required to get my Level 2 cert, I'm going to exceed the allowable ceiling at the launch. Its a good problem, I suppose, but it means a rethink of my plans. So it looks like a chance to relaunch my L1 rocket at the May launch, and it get ...

Interference between devices

I'm planning to install a BRB GPS unit, and an RRC3 altimeter in my next rocket.

Is there any risk of interference between the two devices? Can I put them side by side on the AV sled without any problems?

Thanks

Re: Missileworks USB-10 dongle connection problems

Yes. The RRC3 is still on th esled and powered up.

Is there a particular sequence that I need to follow when connecting & powering the dongle/RRC3? Should it all be connected, then power up the RRC3, then "connect to host"?

Re: Missileworks USB-10 dongle connection problems

Yes and yes.

I have tried it plugged into the RRC3, and with that turned on and off as well. I get flashing diodes on the dongle, as well as on the RRC3, but the computer doesn't seem to recognise it.

Missileworks USB-10 dongle connection problems

I have a new dongle to download info from my RRC3. According to the manual, when I plug it into the USB port, my computer should recognize the new hardware and download the driver, but nothing happens. I tried looking for the driver on the missileworks website to no avail. Can anybody help? Thanks Cam

Re: L2 build

[quote="ROCKet STAR"]Sounds like a fun project. Not sure if you are planning this, but it would probably be a good idea to glass the phenolic tube. It would probably hold up to Mach 1, but I think it may struggle close to Mach 2 without strengthening. Thats probably a good suggestion. I've...

L2 build

I've made my decision and done a first pass design for my L2 cert rocket. Hopefully it will be ready for the May Launch. I want it to be versatile and handle a range of motors, and so I've designed it to hold a CTI Pro54 6 grain case. That will give me I,J,K capability. In order to make the most of ...

Re: My second build.

Thats pretty fine craftsmanship there digit. Where did you get the fin jig? I've gone for fibreglass fins instead of balsa. a 1mm thick sheet is fine for smaller rockets like yours. It cuts with tin snips and is very forgiving. As the rockets get more powerful and faster, the fins need to get thicke...

High power motor selection

I'm moving up to do my L2 and L3 certification. I'd like to do these in 2 logical steps, at the same time ensuring that I don't overstep my competence and cause a costly (or dangerous) failure. I am thinking of going to a 54mm motor for my L2, which will give me access to I-J-K motors, and a couple ...
