Primed and sanded (mostly). Waiting for the Nosecone to show up, and decide if I want to use a “flush mount” engine retainer, or wait for the screw-on ones to become available again. Also need more primer if I decide I really want to make it smooth.
I am considering doing my certification launch in the "half size" configuration. My only hesitation with that is that it will (obviously) go much higher and I see so many recommendations suggesting avoiding that for a cert flight. To be fair, I'm a long way away from that since I need to actually joing NAR or Tripoli, and probably attend a launch or two to see how everything operates and meet people and get people on-board with certifying me, yada yada.Looks like an...excessively stable...rocket. I have one with almost exactly the same outline except that it's built around a BT-50 (24 mm). Launch should probably be in zero wind.
I wouldn't worry too much about flying out of sight. Either fly a tracker, or else hang around enough launches to get comfortable with what size and altitude of rocket you can keep in sight and act accordingly. (But really, fly a tracker.)I am considering doing my certification launch in the "half size" configuration.

On a personal note, the entire "meeting/socializing with strangers" is the most difficult hurdle for me to overcome. I have irrational levels of anxiety about showing up to events full of people I don't know...hell even events full of people I DO know. Posting on this forum is a first step for me to start to feel somewhat comfortable with the community. But, in the mean-time, i'm just working on my rockets.
I am sending an email to eggtimer tomorrow…I wouldn't worry too much about flying out of sight. Either fly a tracker, or else hang around enough launches to get comfortable with what size and altitude of rocket you can keep in sight and act accordingly. (But really, fly a tracker.)
Re. meeting/socializing with strangers, I'm right there with you. I am shy to a fault, and getting to my first club launch was a major step out of my comfort zone. I will give you this encouragement: I've never met as friendly and helpful people as I have in rocketry, which is good, because in my two years back in rocketry, I've met more people in less time that at any other time of my life. Swallow your anxiety, make yourself take that first step, and you'll be rewarded.
What is that bar for?Nosecone arrived!
Big shoutout to rocketryworks for printing these AND including the first shoulder they printed that was out of spec. The out of spec one turned out to fit better!
It look like an anchor point, or to strengthen the partWhat is that bar for?
Wouldn't use it for an anchor point. The print is weakest along the print linesIt look like an anchor point, or to strengthen the part

That boy tallllll!Busy weeks, but a bit of progress. Epoxied the Nosecone, sanded, primed, sanded, painted, sanded re-painted.
I got most of the paint done on the main rocket. (Having given up on having a smooth finish).
Still waiting to purchase engine retainer, and recovery gear. Also need to install the baffle (but I’m still debating how I want to do it since it’s a bit too small for my tube).
I plan to use “military style” stencils to paint “L0NG-B01” on it.That boy tallllll!
I can't wait to see if fly

I gotta learn to stencil on lettering onto my stuff. So hopefully i can take some notes from you!
Without engine, the entire thing is 64oz.Nice Job! What is the weight fully loaded?
I'm not sure I would risk a 4+ lbs. rocket on a G motor. A G motor doesn't really have enough total Impulse to get the rocket high enough for a safe flight using motor ejection.Without engine, the entire thing is 64oz.
It sims fine in OR (to about 450' apogee)...but since that's technically a "high power rocket" at that weight, and I want to test it on my property, I've decided to do the test flight with just the bottom half (and nose cone of course). I wanted that to be an option anyway, so at least I'll know everything in the bottom section is solid before going for certification.I'm not sure I would risk a 4+ lbs. rocket on a G motor.

Just fly it on a mid range H motor, or even go with a I motor if the day is good and winds low.
Also, I'm a moron. It's 64.4oz with a G motor installed. 60oz "dry."

Yeah, that drops me to 43.4oz with a G78G motor installed, and should apogee at about 900'.Good idea.
Will that get you below 53oz/1500g, for Class 1?
Which G motor?
What exactly are you testing? I think I would just fly it on a H motor for the cert as a first flight.

What's going to happen when you put a large I motor in it? If you believe it can handle that, what is flying half the rocket on a G motor actually going to tell you?
Don't overthink this.
