I am looking for some information on some of the rockets that were flown at Thunda.

I have some info already, but I am still missing the following:

Karl's 1/4 scale V2 ... motor?



In addition to my pm George, Karl and Noel flew the 1/4 scale V2 on an Aerotech N2000W

Re: Any experiences with checked in airline luggage - rocket and AV bay

Also, unless they have changed what gets detected, when you fly back do not worry about black powder or AP residue on your clothes if you get the explosives scan thing. Some years ago I was scanned after a launch in WA, I was sure the alarms would go off...but nothing. The security guy told me they ...

Re: L1 Build - Upgraded Loc IV

The on-board flight video is excellent! Regarding the altimeters, I'm pretty sure the RRC2+ altimeters are Mach immune so you will have no problems flying through the Mach transition with these. I'm not sure about the Co-Pilot though...I would use this only for sub-sonic flights up to the Mach trans...

Re: Need to buy or borrow a CTI l1395 or l1355 for a two stage flight.... that just maybe is crazy and well thought out

Thanks Matthew,
If the mootor lights with an ematch it has the pyrodex in the top grain, if it has a larger pyrogen covered igniter then it does not. I saw an email from Noel that said they will introduce some increased drag to decrease the altitude and use an M840 they have in the sustainer.

Hi Matthew/Noel
If the M1830 keeps you under the altitude limit Noel, I can bring my 4G AT M1297 to give to Matthew and you can replace it later, that is just an option. I presume the M1830 has the pyrodex slug... :wink:

Matthew, Noel's phone number was close...it is 0423 101 331

Re: L1 Build - Upgraded Loc IV

One thing I forgot to mention: Aerotech DMS motors no longer come with a protruding nozzle at the back of the motor or a red cap to hold the igniter in place. This image from the instructions is incorrect. https://i.ibb.co/CPJsN9G/Image-8-4-19-at-10-26-pm.jpg I used some masking tape instead, so no...

Re: Can I....

I don't think there is an option to just come as a spectator, so it looks like the fees are the same if you attend to either watch or fly. This kind of makes sense at a launch like this to pay for the infrastructure and organization of the event. Also it would be hard to know who had paid flyers fee...

Re: What is your project for Thunda Down Under 2019?

We didn't quite get to finish the booster for our 2 stage project for Thunda, but we will be bringing the sustainer with us to fly on it's own. Again we made two of them (red ones) so that if one blows up, we can still fly the other. One has a thinner wall and is lighter and the other has a thicker...

Re: Which AT 38/360 or 38/720 reloads for airstarts?

Yeah, I never got the sustainer back, I suspect it ended up in the dam...and yes it is true that it is hard to fly it again like that Matthew. :wink:

One of these days I'll re-build the sustainer...but I'm in no hurry. 8)
