I remember hearing 29.92 inches last oktoberfest. Not sure how representative that is though…

Yeah – the GPS would only be an estimate (accurate to 20 or 30 feet).

I’ve always used about 5300 for both. I’ll have to haul the GPS out next launch and get some numbers.

The file I posted should be compatible – it is a .eng and I can open it in my trial of spacecad with no difficulty. Try it…Also, if you post .eng data, rocksim can use it. They are mutually compatible…   Read more»

Can you post the .eng that you’ve been using?I’d love to see it, just to compare it with the one I’ve been using.I know about the bad data talk, but that sounds like REALLY bad data.Here’s the Aerotech data that…   Read more»

930?How on earth…Mine sims at 830, and it is lighter and (theoretically) less draggy than yours…That sounds like bad motor sim data to me…As for the rocksim question – it has a feature where it runs a lot of sims…   Read more»

I realize that. Mine has quite a high ballistic coefficient though, and keep in mind that I have smaller fins. Rocksim says that I have optimum mass, though we’ll have to see…Should be interesting, no question

13.5 😯 😯 8OMine is at what simmed to be optimum mass for me, which is 8.6 oz with motor.How did you get 13.5 oz of rocket?At least yours will be easier to track off the pad…

It’ll be an interesting comparison between mine and yours…My finish is relatively crude compared to yours (from the sound of it), but on the other hand, the ultralight cf allowed me to shrink the fins slightly and allowed a little…   Read more»

Oh – I’m keeping a little. I have a LOT though in comparison to the size needed for fins, and it was relatively easy to make. If I needed more for next year, I could use $10 worth of CF…   Read more»

Good luck to you too, and by the way, if anyone wants some 0.035″ CF plate, I have some left over. I’ll give it away to the first taker at the next launch – I have 2 pieces. They are…   Read more»

Oh yes – that part is guaranteed :)Mine sims at ~43 gees off the pad – should be interesting trying to track it with no flame or smoke…

Funny – I payed a LOT of attention to the fins, but neglected some other things…We’ll see how it turns out…

Well, I swing tested it today (I didn’t really trust rocksim fully on this one, even though it says I have 2 calibers, because the fins seem so small), and it worked perfectly. Completely stable.Now I just sit around and…   Read more»

Speaking of Wilke charges, we’ll have to see how my SSS rocket does. The FULL G80 charge (anyone know what that is? Something like 1g IIRC?) will go off in a 29mm by 1/2 inch space. Should make for some…   Read more»

Well, the rocket is (almost) done – just need to fill in a few pinholes.Mine sims lower on the old G80 too, but it still sims to 7200 on that motor, so I think a mile should be obtainable without…   Read more»

In all honesty, if it doesn’t cato, breaks a mile, and I recover it, I’ll be happy. 7600 would be awesome, but a nice, decently high, recoverable shot is all I want…

I have only had one cato, and it was a relatively insignificant one, causing little to no damage…I think I too am due…We’ll have to see, and if all goes well, I should be good for 7600 or so…As long…   Read more»

I never thought much about this… CATOs are pretty rare. Then I had TWO G80s CATO for a TARC project! AAAAAAGGHHHHH!!!!Do *not * use lot #010406!Some of you guys might be interested to know that the G80 that blew up…   Read more»

We have an 8 inch dob and a 10 inch RCX400. The dob might be a good idea, but I’ll rely on binocs and unaided tracking for mine…I just layed up some carbon sheet for my SSS – now I…   Read more»
