Also testing my stageing device as well. The deployment device is a version of Franks' device. Unfortunely the nose cone came off before the deployment device would of pushed it off so it didn't get a chance to test it on this launch. When I was going for a second launch the stager released the second stage while I was still pumping. Which of course I wasn't filming and this time the nose cone stayed on until it was pushed of by the deployment device. The only problem being it was about two meters before impact due to the unexpected early launch not giving it enough height.
Here's the first launch anyway since I enjoy the footage I got.

And so did we! Thanks for sharing. Were there two dropaway boosters or was one of the early falling objects the nosecone descending on its own chute?Deckard wrote: Here's the first launch anyway since I enjoy the footage I got.

There was one dropaway the other object the what I call the interstage section which covers the chute of the first stage which didn't get a chance to open. I do want to do more stages just for the looks

Thanks for sharing the video. Everyone can learn from the launches that work and the ones that don't work. That's what it's all about!Deckard wrote:There was one dropaway the other object the what I call the interstage section which covers the chute of the first stage which didn't get a chance to open.

Other than not having the camera running at the opportune moment, do you have some analysis of what went wrong with the stager?

Re: Parachute deployment test launch
The stager is a gardena type connector with the spring removed and arranged so the spring pushs it open. It's held closed by the pressure of the first stage inflating a bicycle inner tube against the inside of a pvc pipe connected to the ring of the connector.U.S. Water Rockets1 wrote: Thanks for sharing the video.

On removing the pipe I found unsurprisingly the the inner tube had got wet from the first launch. The water acted as a lubricant between the inner tube and smooth PVC pipe. I need to add a ridge to the inside of the PVC pipe which I was going to do originally but skipped it since it had such a good grip without (dry of course).

Re: Parachute deployment test launch
That makes sense. You should also dry the thing out between launches if possible. Leftover water can fool you into thinking something has leaked when you fill it up the next time.Deckard wrote:The stager is a gardena type connector with the spring removed and arranged so the spring pushs it open.
