What’s flight weight? How much do you expect to charge for them? The last time I weighed one with an accurate scale, it was 7.6 grams, but that was my first prototype. Since then, I’ve added some components, including a…   Read more»

Oddly enough, I have not flown an A, B, C, or D motor in perhaps 15 years. On top of that, I have never once flown an E. Given my geographical constraints, mayhaps I will revisit that whole paradigm (hey,…   Read more»

Excellent Adrian. It’s a really sweet product as it stands. What’s flight weight? How much do you expect to charge for them?Warren

Let me say up front, before I’m tempted to talk any trash, that I really respect what you guys have done, both in the area of records (John’s G record bird is (was? :() a thing of beauty) and more…   Read more»

I’m genuinely delighted to hear about the renewed enthusiasm with altitude.Oddly enough, I have not flown an A, B, C, or D motor in perhaps 15 years. On top of that, I have never once flown an E. Given my…   Read more»

Just a short f/u to Warren’s post–Nar rules/records prohibit modification of motors in any way, including removal of BP in SU motors. TRA does not–which is one reason for the wide disparity in altitude records. In other words, w/o removing…   Read more»

Well first you’ll have to beat me and John Wilke – you can damn well bet he’ll be defending his standing records and since I’ve got probably the last few F32’s and G55’s in Colorado, you can bet I’ll be…   Read more»

I suppose I should be asking Tom Rouse this, but do you think that the ejection charge reduction/elimination would disqualify a Tripoli attempt? When I go for the F record I want to make sure I tag all the bases.

Agreed, though below about K impulse or so, the problem with a boosted dart becomes squeezing the recovery components into the tiny dart…

Boosted darts have a significant advantage on standard 3FNC single motor rockets in terms of altitude. Basically my half=assed boosted dart could almost certainly beat the crap out of your super-optimized 3FNC bird on the same motor any day of…   Read more»

Is a bossted dart really different then a single motor vehicle? You could say that the dart drifting is similar to a single motor rocket drifting, the only difference is the dart breaks apart. I think a boosted dart should…   Read more»

As a club, NCR is usually considerably less rigorous about the rules surrounding altitude contests – a big for instance is Tripoli expects the bird to recover in certifiable and reflyable condition. NCR doesn’t insist on that, we just consider…   Read more»

Is a “boosted dart” an unpowered payload section that recovers separately from the booster? I checked out the Tripoli rules and boosted darts aren’t disallowed from single-motor records, though they are disallowed from the staged records. I also found an…   Read more»

I have some questions about record rules:Is a “boosted dart” an unpowered payload section that recovers separately from the booster? I checked out the Tripoli rules and boosted darts aren’t disallowed from single-motor records, though they are disallowed from the…   Read more»

Well Mr wilke a more stoic attitude could only be expressed by some guy in a Gulag prison and obviously I our notions coincide on some level–which is what I was trying to address. Honor those who make the effort…   Read more»

I’d love to see NCR north become the place to set records–at least w/in the waiver limits/ By not recognizing field records, one can come out spend a bunch of $$, and maybe eclipse the record but not by the…   Read more»

Chris, just how much hotter has it to be? Ignoring humidity, can you do a 3-D plot? impulse on the z axis, AGL on the x, and T on the Y. Of course insoluble in closed eqn, only curious if…   Read more»

well if science backs our opinions–why not? If anything I would have suggested last summer and maybe JW will concur, that Hartsel can be a disadvantage due to the winds that attend any decent temperature. Than something really strange happened…   Read more»

Also, on a side note, this difference is small enough that a 40 degree fahrenheit day at Hartsel is almost exactly equivalent to an 88 degree day at the north site (for density of air). So, a hot day up…   Read more»
