Do you have any 54mm motor mount tube? If so I’ll take one.

It must be an extremely high speed video – watch how quickly it ignites on the main video to compare. I do wonder whether the darkening is more a product of the igniter burning out, or whether it is simply…   Read more»

4 grain is the standard Shuttle load – the full load for Ares will be a 5 grain. Here’s a video of a static test of the 5 grain//www.youtube.com/watch?v=E3cPKgFKe0Y&feature=relatedAnd some high-speed video up the core showing the igniter firing//www.youtube.com/watch?v=CGImLZpQDwY&feature=relatedWow! That…   Read more»

Size dosen’t really matter, does it, when you’re talking almost a full load? And I thought the three grain load was special. Yikes!!! That really is an incredible picture.

If you consider the alphabet to wrap around (I.E. x..y..z..aa..ab..ac..), the SRBs would be a 1.24*10^9 AD 10 million using CTI notation (1.24*10^9 newton second AD10000000). Assuming I did the math right of course…

I was thinking the Mother of all Clusters.1 Trillion H999’s

That’s essentially a 4 grain Shuttle booster as the 5th grain was a spacer (ala Cesaroni!). I believe you’re talking in the double letter ranges… something like WX I’ve heard.W

The 70G version has a lateral accel axis also. I recommend the 70G version because the axial accel has better resolution and can be calibrated more accurately. The lateral G information is sometimes interesting also, for things like seeing how…   Read more»

Adrain, Thanks for all the hands on information for the Raven.So, is the difference between the choices, 250 G singal axis, or 70 G dual axis?besides 180 G’s?Wow, is that even possible 250 G’s model rocket?ThanksDavid

See what happens when an English major get his hands on a paper… I’m glad you made this up Adrian. Geologists can only be tech savvy to a point – as you saw earlier. Had to add this in now…   Read more»

What really happened is I said “Adrian, I’m a bit of an idiot on electronics sometimes and I need you to essplain some of this stuff to me” 😀 In all sincerity, thanks for spending some time with me on…   Read more»

Thanks to John Wilke’s helpful redlines, I updated the Raven’s user manual. It’s available here//www.featherweightaltimeters.com/uploads/Raven_Users_Manual_09Nov8.pdfRaven link//www.featherweightaltimeters.com/The_Raven.php

Can’t wait for Saturday….. E-bay is sitting waiting for it to arrive….I’ll have a bunch of Ravens with me all boxed up and ready to go. Now will I have my BALLS sustainer fixed up for an altitude attempt? We’ll…   Read more»

Very nice.

I still haven’t figured out all I can do with the Parrot yet and I want one already. Are they calibrated to NIST-traceable standards?WarrenThanks Warren. Yes, the sensor is is calibrated at the chip factory, and since it has the…   Read more»

There are plenty of hunters who are “real sportsmen”. FWIW, the antelope that was shot near the gate was shot by a 12 year old kid………………When I was a lad, you had to be 14 and supervised by an adult…   Read more»
