I'll be in, and I have a couple of potential designs that are easily in the 100g range. 200 gees is possible, though expensive (my only 200g design involves a J1299 and 6 H999's, which at 1800lbs aver...

Sorry, but 300 was the claim. Y know me. Produce a rock sim that shows 300G's I'll buy it.--provided its accelaration and not dee 😛 And a bit of a vent, I go point on this mission and there is no back...

I can't get 300 - even a MD rocket with no payload will only do 230 on the I1299. I can get a solid 90-100 gees with the J1999 though, and I'll do one better than just no broken shell: I'll bet that n...

Couple seperate subjects: re the Eggs, it is doable, as I have argued from the beginning. But whether mother nature or the best thru-hole electronics balks first might be the best question. I seriousl...

If it's an organized event, I'll go H999. Otherwise, if it's just kind of a fun event, I'll go J1999. So, which will it be 😆 As for the yolk thing, I theoretically got an egg to well over 300 gees, an...

I have to agree on that. I have looked into some designs, and I think I have what I want to do picked out. It should be pretty fun, and the E BG's have some real potential with the E6 motor.

Well, I don't see E BG anywhere in those - Nate'll be disappointed (as will I) Other than that, I like option B.

Honestly, you probably have as good a chance that day as any. All of us who go there every month manage to procrastinate and all fly in November anyways, so it's not like we pick and choose the month ...

That must be one helluva wind shear if it's shredding rockets when they're already at near mach or greater speeds 😯

Well, the NCR folks will see it polished and painted before anyone else 🙂 It should be all nice and pretty by the flight at Mayhem. With any luck, the paint won't be scratched up for its LDRS flight 😀...

I used the time-independent acceleration equation, V(f)^2-V(i)^2 = 2ad In this case, after a fall of around 15 or 16 feet (around 4.9 meters), the velocity works out to be right at 9.8 meters per seco...

I'm not saying anything you commented on is wrong. I have no experience with your tapering method, so I can't comment on whether or not it works, and I will definitely have to try it sometime. If anyt...

Nope. Simply knowing the speed at impact and estimating the distance that it stopped in based on the amount of deflection needed to cause a crack of the kind observed in the tupperware container. Turn...

As far as resonance goes, I have to disagree with you about cf vs fg. The nice thing about CF is that it is FAR stiffer than FG, so the resonant frequency of the resulting plate goes way up. Although ...
