Re: Vertical Trajectory System (with some 3D printed parts)

There is a G-switch wired into the circuitry as well as the altimeter control. If the acceleration is over 3G the electronics just commands centering of the servos. I don't want any extraneous movements when the accelerometers or gyros are pegged. Servos are actually actively centered when the VTS f...

Re: Vertical Trajectory System (with some 3D printed parts)

I am actually reconsidering my earlier finding about the behaviour during coast. Need to think about it some more, but too much happening for me to concentrate on that currently. Could go either way still...

Re: Vertical Trajectory System (with some 3D printed parts)

Working Towards Flight One Make a list, check it twice... Made up another list of things I need to do to get this into the air. Surprisingly long :( The original M4 metal spacers holding the fiberglass discs of the assembly together were replaced by titanium bike spokes (custom cut) and some CF str...

Re: CRGs' June 2018 HPR Launch at Ardlethan

Congrats on the good day and flights. Highlights of the weekend included an L1 certification for Marcus, and two flights to over 12,000’ for Warren. This broke the CRG altitude record by over 3,500’. We will soon be pushing up to our 15,000’ foot ceiling. Might need to increase that! If you get GPS ...

Re: Binder Design Velociraptor

How did the 3D printing hold up?


The 3D printed NC now has well over a dozen flights. Except for the cracks (now repaired) that happened on my Nike Apache flight about a year ago, it is no worse for wear! No more cracks evident. Nowhere near the end of its life.

Re: Binder Design Velociraptor

Still flying this bird. Went to a Melbourne Amateur Rocket Society launch on 16-17 June. Another nominal flight, this time on a CTI L730. She hauled about 24G accel off the rail, and peaked just below Mach. Apogee was 10819'. A-PEaWtPluo Excuse my average video skills. This is a new phone I am just ...

Re: Airframe choices (or why you should consider rolling your own airframes)

AusRocketry sell couplers, but all small sizes. Nothing long enough to roll on. Email Blake at info@ausrocketry.com and ask for whatever length you want. He gets longer tubes and cuts them to size. Don't forget to make it a little longer than you actually need as the ends of hand-rolled tube are no...

Life is to short to spend too much time thinking sometimes. I am sufficiently curios so I pushed the "Buy Now" button.
