More than any single letter impulse class – that’s for sure. SSRB’s do 1.5m# for 120 seconds or so… and I believe in our system they are like WZ class motors… I saw that somewhere or something like it. Be…   Read more»

FYI – I moved this topic to a more appropriate forum.I’ll be flying my L3 bird (still not painted yet) on an M795 – expecting 22K+. Also probably flying my L2 bird on an L1300BB and possibly also on a…   Read more»

3 very excellent pictures.W

If this guy or his crew regularly do this sort of thing, it would seem a good idea to cultivate them and at least get contact info from them a a 6-pack or something nice for him. You can never…   Read more»

I’m always so impressed by these upscale projects that folks do. I’m still stuck in the land of 3FNC and 4FNC birds, usually minimum diameter.Good luck with this project Mike – looks awesome.Warren

I should be out at the September launch – Oktoberfest most definitely. I’ll show you some of my v-bagged layups. I typically vacuum bag everything I do. My specialty is v-bagged tip-to-tip reinforced fin cans integral with the airframe. My…   Read more»

Having built boats and a fair number of all-composite rockets over the years, I feel I have a little background to make some comments.Cure time has little to do with strength, although depending on the specific polymers involved, accelerated cure…   Read more»

I’ve gone through 3 identical EZ-shade brand 10’x10′ sunshades over the last 7 years – one from Walmart and the other two from Home Depot at prices ranging from $96 to $135. These are reasonable quality for the class of…   Read more»

Oh it is definitely the cool factor. Over-building has always been my path in most everything I do – remodeling, automotive, rockets, etc. If you check out Tony’s post on the Kestrel, you’ll see what needs to be done. I…   Read more»

Hmmm – don’t know why I didn’t reply to this when it first showed up.Glass – good all around use. Cheapest option. E-glass is standard, S-glass is lighter for a given strength.Kevlar – Impact resistance par supreme.Carbon – highest rigidity,…   Read more»

John, if anyone knew the details of the BALLS shot, it would be absolutely clear we were smoking something… as it is, we might just set a field record at the north site with this baby. Under 4# and on…   Read more»

Well I dunno if it is small. I was figuring we’d be flying one of the AMW L1300 BB motors I have in the magazine. Alternative, if it is coming out of my magazine, would be an AT K550 or…   Read more»

A cattle guard would require a double gate, a change in the ditch and culvert at the gate… probably a non-starter with the Forest Service, but it would be worth asking.W

I feel for you Ken. I’m still out after a year and 3 months. Aside from the occasional consulting gig and some small networking projects, the well for me has been dry. This is by far the longest I’ve been…   Read more»

Am I to assume that the lovely dark-haired maiden is the infamous “Art’s Girlfriend”? Jeez, back when I was that age, rocket geeks never got the hotties…In all seriousness, great pics Art. Glad you guys had successful flights.Warren

Quite frankly, traipsing about the prairie searching for rockets has never been high on my list of enjoyable activities. GPS saved the hobby for me.

My DC-20 is mounted flat on a bulkhead with the antenna going straight up into the nose cone on my 5″ bird. Even uses the same mounting screws.

Congrats to SpaceX – this is the first new-space company to reach orbit and the first orbital flight where development costs were NOT paid by a government entity. Elon did it….finally.Warren

With the experiences of folks like John Wilke and various sundry others I found on the web, the ONLY BP charges I do now are surgical tubing… Won’t even bother with anything else. My L3 deployed flawlessly.W

All my sympathies Sean… such a gorgeous project, such a nice Up part to the flight. All my best on your next try.Warren
