Gotta give Ya props for getting me thinking about the tube spacing. That extra.125" between centers on the rear centering ring/thrust plate/landing pad seem to have paid off. So far, so good. I really want to put those last two tubes in but I have to be up early tomorrow so I guess their just gonna have to wait.
Thank You Sir. Long distance high five for the super service....
Chuck; I make no claims about being a machinist, I'm a retired Union Carpenter that loves to tinker with and fabricate "stuff". That is a Harbor Freight combo 9"x34" lathe mill combo machine (which pretty much means it's not great for either
). The lathe actually isn't too bad, the mill is almost useless but I've had it for about 11 years and it's paid for itself several times over.I have Rocketflite clusterfire (Clutermaster Boris Kataan swears by it) and Eggtimer Quantum (at least 'till I can afford a 4 pyro altimeter) for now. Multiple airstarts is my eventual goal. I know, stupidly expensive but oh so cool...
I hope never to see 10 G's, just used it as worst case scenario. Haven't even looked at volumes or even chutes yet. I figure it's easier to get actual built weights first. The weights I posted are educated guesses using a combination of actual part weights and historical guesstimates on recovery/glue/paint and don't forget the all important whatnot. My Y harness will not be easy to replace so I just need to be sure it'll handle those weights @ 10 G's. If so, I'm gold..
That seems kinda high. Can you explain further?
Looks to me like they realized the fin to body tube connection was a weak point. The instructions reflect this, the fin tabs do not. Odds are I received new/updated instruction sheet and new old stock fins?
rding the fin tabs. This way we'll know for sure. And I had a pleasant surprise awaiting me this morning. Everything fits like a glove. If you like a challenge, I highly recommend this kit. Price seemed a bit high at first for a "cardboard" rocket, but it is a very "complete" kit. Comes with everything needed (if you intend to fly single deploy that is) even has all needed hardware, harness and even a chute. And it's just so damn versatile w/7 motor tubes. Potential flights are almost endless, be prepared to waste an entire day playing w/sims. 
). Here's an example, if I remember correctly it's an Eggtimer Quark with and ordinary toothpick and a grain of Minute Rice for reference. Believe that was shot through a 7x loupe. Cool huh?
Wow, just Wow! Did not expect that kind service at all. Thank You kind Sir and or Madam (having a hard time with all this political correctness crap, I'm old dammit, can't I just be old and set in my ways?) I will absolutely be doing future business with you guys. Just for the record: My original package had a crunchy body tube and unfortunately it was the sustainer with the shipping damage at the aft end near the fin slots. since this precluded me simply cutting off the damaged area and carrying on I shot Loc an eMail. 2 Days later a box was at my door with a shiny new tube. The fin issue I could have worked around and actually already had a plan in place. The only thing missing was execution of said plan. This will be a huge time saver on my end. Loc Rocks!
Once I got my computer running again and could use O.R. I played a bit with sims/mass objects/motor combos and discovered that with all the mass I'm adding up front with the av bay, main,harness and whatnot that I could mod the stock/short tab fins and still be plenty stable. Burying them an additional 3/8" at the root only shifted the CP forward .631" so even with 7 G75's I would still have close to 1.5 calibers stability. These pics are just for reference since they're not real world weights and numbers, just an RKT. file I found on rocket reviews and modded using some actual weights and approximations. After I complete the whole mess I'll create and accurate file and post it then. For some reason the file I found on Rocket Reviews did not accurately reflect the actual kit. 
How cool is that...I thought those numbers were suspect. Either your rockets are impossibly light, or your hardware incredibly heavy...
