120 G’s !!!!
That’s whatcha call “Ludicrous Speed”.120 G’s !!!!
The sim says 153g's on an H999 at current weight
I would imagine - after pulling 100G’s It’s all Academic...I have noticed that with sims (more so RockSim), after 100Gs it starts to exaggerates. I have a small one that sims at 170G with the H669 and it only got too 99.3G. Next flight with that rocket on an H999 sims to 230Gs, but I don't think it will go above 150Gs. But with my Raven V4 maxing out at 105Gs I will not be able to get an accurate reading. All none Warp 9 flights with this rocket have been +/- 2 Gs from the sims.
One thing I noticed is that the burn time on my last H669 looked like 0.4 seconds, which could explain the lower Gs.
3” diameter, 10” longWhat are the dimensions of a stock Big Daddy body tube?

Big Daddys going big. BTW I used about six ounces of nose weight on Angry Daddy to balance it where a stock Daddy balances with a D12-3; just slightly in front of the leading edge of the fins at the root.
3.0" O.D, 2.93" I.D., and 10" long.What are the dimensions of a stock Big Daddy body tube?
Hmmmm.... I have a piece of 6" carbon fiber body tube about 20" long. Upscale time? Is that a 3 to 1 or 4 to one nose cone?3” diameter, 10” long

That means I might have to make my own nosecone. Cant find a 3 to 1, 6" cone....
Due to the 1/8" fiberglass fins I used, the Angry Daddy started out relatively tail-heavy. Using a two-grain 54mm motor, a decent percentage of motor weight is ahead of the target CG, so that helps some. Point being though, using the stock CG location will keep the rocket stable at least to around Mach 1.
I'm on the road now but will try and get you that on Friday.What does the Angry Daddy weigh?
Inquiring Minds want to know... remember that old tag line?I'm on the road now but will try and get you that on Friday.
Angry Daddy weighs just over 25 ounces with all recovery gear. Add a small amount for the chute release and T3 GPS.View attachment 435871
For some reason you now have to download the attachment to view the file.Flew my 38mm Big Daddy on a H219T Blue Thunder at AirFest, gone like a scalded cat. Hope someone finds it…
First, are most of you guys running 1/4" lugs or 1010 buttons on your kit bashed Big Daddys? Second, with such a short airframe, how do you pack the chute (especially when running longer motors)? My 24" chute folded 3 times down to 3" long, has 1" of space between it and the 5" motor mount tube! Third, the Vander Burn upgrade kit comes with 3 centering rigs and an 8" motor mount tube. I'm assuming I should cut it down and only use two of the centering rings?
1/4" lugs.
Both my 38 and 54mm Big Daddy's have no bulkhead in the nose, just a kevlar tether on a glued in anchor with the nose weight. The parachute winds up largely in the nose.
I have two centering rings in all of mine, and the MMT is no longer than a 38mm H.
