Ha, true! 18 holes of disc golf in the snow, she was cashed. For that matter so was I, but wanted to see tower together for a dry run.The doggie is not impressed, Justin.
In all seriousness, it's really looking good and coming along very nicely. Looking forward to the video of the launch this Spring!Ha, true! 18 holes of disc golf in the snow, she was cashed. For that matter so was I, but wanted to see tower together for a dry run.
Just curious... what is the reddish material that was applied to the tip of the nose?

Neat thought, but probably a solution looking for a problem...
Thin CA, then dab on CA accelerator, then rinse/repeat.What do you tack that stuff down with? superglue? 5min epoxy? other?
I just hastily put together an OR sim. The airframe diameter is 4mm with 0 wall thickness and this is just my concept from the photos you've shown to this point. Interestingly, the rocket needs a lot of inertia for altitude. My sim shows only about 24K feet at a 3,800' launch altitude AGL ... but it hits Mach 3.45. You really should switch to CF fins. I'm not sure the G10 is going to hold up. When you presss the button, this thing is going to sound like a very loud gunshot.
Here's what I put together. I don't have your fin dimensions, but what is in here seems optimal. You do not want fin height to be less than 1.1x airframe diameter or you may have a serious coning issue. There is 4 oz. of ballast and the electronics, sled bulkheads, etc. are estimated to be 4 oz. Single deploy with a 24" chute and a 20' long Kevlar shock cord.
Feel free to use the OR file if you want. I'd love to see a video of this. Something pulling 55Gs is just a thrill to see.

Kloudbusters high altitude application submitted and approved.
Negative... Saturday March 27, 2021, Argonia Cup Competition/KLOUDBurst 29.Airfest?

Do you know what the rocket's on the pad weight is?
Negative, been too cold. Maybe some primer between now and then, we shall see.Jf
Any chance to paint it yet?
