Re: Australian Universities Rocket Challenge

Well done to all involved.

Out of curiosity is the Uni Rocket Challenge associated with AMRS? Anyone have details about the program?

Re: 9th December Launch and 2018 AGM

Sounds like a great day, congrats David on the certification and thanks Warren for all your help over the years. The Club Annual General Meeting was held once flight operations ceased, with the new committee being elected. I will let Lachlan, our new fearless leader (Congratulations "El Presede...

Re: HobbyKing Mini 3-Axis CNC Milling Machine

Not an expert but you’d need to upgrade the rods and screws as well and then tweak the software. Then you’d loose some strength in the structure resulting in less accuracy (which isn’t ver good to start with). It looks to me that it would work for cutting fins and CRs out of fibreglass / cabonfibre.

Re: Which 9V Alkaline battery?

Joe did a break down last year, need to be careful as manufactures do change the design from time to time.

Re: Joe Turner's 38mm Scratch-Build

I always attach the nomex blanket to the shock cord about halfway between the chute and rocket body. When the chute bundle ejects the shock cord will pull the blanket free of the chute. Haven’t had any trouble yet with this method. When using a chute release, I attach that the the chute and then wr...

Re: Joe Turner's 38mm Scratch-Build

Well this is why we do shakedown flights for certifications... Not sure about the tracker, OTT might be able o help you there. It does look like you’ve overlapped your chute, when my protector is a bit big I will fold the side and bottom corner over on themselves first to limit how far around I wrap...

Re: BlackSky Aerospace

Indeed 8) Nice work Blake.

But the really important question is when can we expect to see this offered as a kit?

Re: Slower than the sim

Nice work on the certification Cam.

With velocity I usually see slower speeds than simmed. I believe this is a result of the sampling rate of the accelerometer.

Re: 11th November 2018 Launch

Really nice to be able to make it today. Thanks all involved in setting up. Congrats on the certification flights. I had an interesting flight with the Flying Dutchman. I had a CTI G185-12 that I wanted to drill to a 9 second delay. I set the tool to -3 seconds but noticed that the drill tool hardly...

Re: Motor weight in OpenRocket

Ignoring Open Rocket for a moment, why does the motor weigh less than the published data. Ie 640g actual versus 702g published? Sent from my iPhone using Tapatalk 702g is the total or loaded weight this includes the case. I weighed my 6G case and can confirm your weight 202g is within a few grams o...

Re: Motor weight in OpenRocket

The motor files for open rocket originate from the Thrust Curve web site. However when I look for a J400 the total weight is 702 same as the CTI web site, which should be the weight of the reload and case. So I’m not sure what’s going on in Open Rocket, perhaps you’ll need to send some screen shots....

Re: Four-Camera HD Video Mount for 4" Rocket

Nice result. The only thing I’d be worried about is the pods making turbulence that interferes with the fins.
