Isaiah,
Noticed you were asking about min diameter rockets in another thread. While not a min diameter...this thing IS capable of ~13,000 feet at Mach 1.5 with the really rough calc I did on it a short while ago...
That in itself will be plenty of work to track :wink:

Hmmm... I remember a post somewhere about split fins and Mach, but cant seem to find it at the moment (yes, i searched, but brain no workie this morn)....
So... What are the problems (if any) with split fin designs and Mach?

None really, other than the minor note that they are a bit worse structurally than solid fins, and as a result, they're a bit more prone to flutter. I would imagine the darkstar comes with fins plenty thick to handle the stress though.

They're still available on Tim's site. He was able to get a second batch ordered. Delivery would be late January for the latest run.

Needs work, based weight in G10.
edit- updated, scaled down from 4" and included hardware, chutes, etc. Weight seems a little off, but that can be worked out piece by piece when we get the kit.

If you build it the WM suggested way you won't have a problem. Use good epoxy, I use West System, inject to the MM Fins and CR's and do good external fillets. Great rocket just didn't need to add another DarkStar to my queue of 2.
Just looked on Wildman's webpage and they are still selling it for $159 or you can join Wildman's club and get it for $119. Club membership is only $30 and lasts for a year from time of purchase. Limited production run, when they are gone, they are gone. Can't imagine anyone who likes HPR not lusting after this rocket....
Hey, I'm a scratch builder myself, building a 54mm minimum diameter FG rocket right now. Already have more in it that I spent for the 3" DS, but that won't keep me from lusting....

Even if you love scratchbuilding, this kit was so cheap that it would be worth the price just to harvest for components. The nosecone and a single section of tubing alone are worth the price.

I've never even launched anything with a 38mm engine yet and I haven't been able to stop lusting at that thing since Saturday morning. I keep going to the site and talking myself out of it.

Come on...ya know ya want it :wink:
If you're TOO worried about motor size, you can certainly get an adapter so you can fly 38mm's in the 54mm motor mount. Even something like an I236 Blue Streak will make this little guy hit 2400' at Mach 0.43.

I kept doing the same thing all day. I just failed. One less available. That makes a RW lil rascal, a mini eagle claw, and now the 3" darkstar inbound. I'm going to run out of space to store these things soon...

Still just staring at it every few hours. I'm thinking I will get whatever great deal Wildman has next year for my L2.

That means some carts timed out
Inventory is decrement end when it's added to the cart, but it doesn't stay there forever
I'm betting they will all be gone in a couple of weeks. I know I'm responsible for four sales of that one rocket! Just got my invoice from Jackie...:y:
Five rockets, retainers, recon chutes, motors and cases......
Here's a question, they recommend a 40" recon chute that is rated for an 8 lb. rocket. Any idea what the "Blackstar" is going to weigh in at?
I heard the profusion fiberglass is heavier than regular G10, can anyone confirm that?
My 3" Wildman weighs in at around 14 pounds with a 5 grain 54mm ready to launch. I'm guessing it'll be close to that.

I know it FEELS heavier and more rigid...bought some plate and some 54mm tubing for a min diameter project. The plate actually generated tiny sparks when I cut it on the band saw...wonder what the epoxy is infused WITH?!?
