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.

Re: L1/ L2 lrocket design

Great kit to do a L1 or L2 certification on. You can fly it short on a G motor to about 2000 feet or with the help of a tail cone you can push it to nearly 11k feet with a J with dual deploy and a GPS tracker. You can read about how I certified on my Flying Dutchman https://forum.ausrocketry.com/vie...
