As usual most excellent project.
Any assistance required consider the "Recovery Crew" in.


Cheers bud! Looking forward to it. Hopefully this time we'll have GPS coordinates to assist!

Re: 54mm to 38mm MD ISC

Also, if I have issues with the EasyMega I'll revert back to a Raven. Here's Adrian's advice on staging with them from TRF in 2013. https://lh3.googleusercontent.com/i0PqRRxkXooxh0nMIBROTog1BpfA7QgtNoZHlwDs-QzgIqd10ZMqsooCCB5RUyb4qYrDVPK6MBNcPlt5qLp0m87V38afaDusNQtQkYkKYqD5i8uWciUoaXrYlFF9v1M3wluGBO...

Re: 54mm to 38mm MD ISC

Hi Drew, Head end ignition will definitely reduce the complexity of the whole assembly process on the pad and eliminate those pesky wires that would either come down from above or into the coupler.... Indeed, especially in the case of MD rockets. Jim Jarvis's TaperWire technique has never really be...

Re: SpaceX details its plans for landing 3 Falcon Heavy boosters

Yeeehhaaaa. That was spectacular. :D I heard someone mention on a live stream that they had overheard the announcer say that the central core was lost at one point. But can't confirm. I suspect that is the case because we would have heard otherwise that it was sucessful. Yea, got this from a mate.....

I like the accuracy of mm and I do not like fractions. I've been converted.

54mm to 38mm MD ISC

So to support my plans at THUNDA in 2019 I'm going to hopefully test a top lit staging stack at WWW2018 in June. I've got a 54mm booster sorted (my 54LB from last year). I just need an ISC and 38mm sustainer. So I've been in planning and production modes at the moment. Below are most of the parts re...

Re: Rotary Tool on Special at Hobby King

So I considered pulling the trigger on this as my dremel died a few weeks ago. But when Ogivemeahome posted that shipping brought the total up to $40 I ended up going to Bunnings and grabbing a $69 Ozito kit as it appears to be the exact same unit but with heaps more attachments and a 3 year warrant...

Re: SunSeeker II

I didn't say anything about boost vs ejection charges gents, I only said that I've subjected AltusMetrum GPS hardware to nearly 47Gs without issue. Usually the ejection charges or the cute opening create much higher g's than the motor will. Depends on the rocket. I'd posit that MD rockets register t...

Re: SunSeeker II

From my perspective I've never had an issue with the aforementioned GPS patch antenna on my TeleGPS. I know it's a different product but it uses the same uBlox chipset and ceramic patch antenna the TeleMega uses, at least from what I can tell. I've pushed that unit to almost 47Gs with zero modificat...

Re: SunSeeker II

Yes, I remember you :-) I'm still looking for two persons willing to track my telemetry. I'd like to have a total of four, two for each computer... But it is still a long time and I might be able to persuade some germans to come over too for the "expense" of being my crew. I nearly offere...

Re: SunSeeker II

Hi Mathias, Thanks for the quick response. FYI I'm the guy that received a few of the packets from your TeleMega on your last O3400 attempt. I too can recommend Carolina Composite Rocketry; Charlie made the HEI forward closures I plan to use for staging at the next THUNDA. I thought those airframes ...

Re: SunSeeker II

FANTASTIC!!! Is that a commercial nose cone or did you make it yourself? Also, is the interior of the NC "empty" for lack of a better term? I can see that you've made the Av Bay out of FGFW so the TeleMegas will have RF comms but the nose looks somewhat underutilised comparatively. I'm loo...
