Re: L2 Attempt Launch 2018 Questions

The accuracy of the sim depends on the type of rocket and the program used. Rocksim is usually optomistic and reads high, and I have heard that OR generally reads low. If it is a fairly straightforward rocket design this is likely to hold true. Make sure you have the final mass correct for the unloa...

Re: Australia closer to a national space agency

Sounds really good. I am a bit skeptical when they start lumping in other stuff with it, effectively watering it down. "Australian Space, Science and Industry Agency". It is getting packaged up with other science and industry, if I am reading it right. Hope I am wrong on that.

Re: Hello from Montana, USA

I will start this post with the comment that I hate politics, here or elsewhere.

There is a lot of work done in the background, and has been done for decades, by the person you allude to.

You probably don't have much visibility on that as you live in the West.

Re: Epoxy resin and bad smell

Glad to hear you got it sorted nils. I use a scale similar to this one, purchased on eBay http://www.ebay.com.au/itm/Silver-Black-100g-0-01g-500g0-1g-Dual-range-Mini-Electronic-Jewelry-Scale-/132230246889?hash=item1ec98971e9:g:grYAAOSwjk9ZRSAN although this one does up to 500g which might be nice :)...

Re: Epoxy resin and bad smell

Do proportioning by weight (buys a small set of electronic scales).

Measure the hardener first as it is a smaller quantity, then multiply up for the resin mass.

Re: L2 Attempt Launch 2018 Questions

Hi Joe. Good luck with the L2 build and flight. One piece of advice I will offer is that you don't know what you don't know. Neither do I for that matter :) These are the things that sometimes bite. Asking questions is great, but sometimes we don't know what to ask. Make sure you watch someone else ...

Re: Learnings: rarely invite your wife to a launch. Do so, only where there is no evidence of your appropriations.

I regularly use the 5kg "kitchen" scales that I purchased for measuring rocketry related items. They live in the kitchen normally now. I don't even get complaints when I take them outside to the workshop for a few minutes. Surprising really :) . I do however buy my own packets of skewers, ...
