Would anyone in the Lafayette, Thorton, Broomfield, Superior areas be interested in looking over one of my designs to ensure it’s flight ready? After my mishap at Hartsel, I’m second guessing parts of the design and would like either a go/no go, change this or that, scrap it and start over, or any other piece of advice that will help me get it off the ground and back successfully at the next launch.

Any advice, good, bad or otherwise would be greatly appreciated.

Hi Ken,

I’m up in Longmont. I’d be glad to take a look.

Thanks Ken. Did you get your L2 on Saturday at Hartsel. Watched a couple of cert flights. Don’t know if one was yours or not.

I sure did. I was the red Intruder with the J350 and dual deploy.

I remember it. Very nice! Wish I would have gotten a photo of it. Any chance we can hook up one evening this week or sometime this weekend for a few minutes?

Hi Ken,

Sorry I didn’t see your post sooner – don’t know how I missed it, but I did. Sometime this weekend should be very doable. Where are you located, and when would be a good time for you?

I’m about halfway between Longmont and Lafayette off of Hwy 287. Let me know if you’d like another opinion. (remember, free advice is worth what you paid for it 🙂
)

Ken, just found this. I live pretty close to you, too. In the Thornton/Northglenn area. Could you send me a pic of your rocket? Is the CG ahead of the CP by at least a body tube diameter? If you’ve flown it, what went wrong? The why isn’t as hard to find out as you might think. Just let me know.

What happened is one of my motors cato’d (post mortem revealed a couple of the o-rings were switched) in another rocket on the 22nd at Hartsel. I was planning on flying for the first time a new bird I just finished, but didn’t because I was pretty spooked after the cato. Anyway, it got me thinking about my design in ways I hadn’t before. Not the design so much as the construction of it. I designed it in RockSim, so I feel pretty good about that (CG, CP, etc), but it’s just how I constructed it I’d like feedback on. This is my first DD rocket and would like to feel really good how it’s built before I fly it – need a little confidence picker upper…

Maybe after I get the aluminum plates done you can check it out too. I can send you a photo if you want.

Thanks
Ken.
