No doubt, every situation is different. I honestly don't remember the last time I flew a rocket that wasn't minimum diameter - Adrian is likely in the same boat.... so from my perspective, QT is not ...

Really? I'd fly warp in plain QT, honestly. It's surprisingly difficult to shred a body tube from thrust alone. I partly agree, but mostly disagree.... you can't fly QT in minimum diameter as it will ...

Interesting. That's the first I've heard of a tracking problem with the dog collar. Was this a Kestrel? This was a custom, 3" min-dia rocket (not a KestreL)

I can't remember who told me that they'd never use the stuff again... I've not seen it, haven't played with it, and I have an obvious conflict of interest 😀 That said, someone was quite upset with t...

For those interested, Sue's daughter is involved in a "race for the cure". Tax deductible donations can be made here

Sean - how high was flight #1 vs. flight #2? did you go appreciably higher on the second boost? The gremlins come out and play at mach 2+ and ~20K altitude... it took me a few swings at the plate to ...

Sean, one way to get around the joiner nut on the eyebolt is to use an eye nut You run that down tight onto a piece of all-thread.. You can torque them down incredibly tight, use lock nuts, and also...

John, hats off to you and Mark for going out of your way to give credit where credit is due. I didn't know Edward had contributed so much to the project -- but I am not surprised. Edward is a "lifte...

I'm saddened to report that the Bert Harless' wife, Sue passed away earlier today. Many of you know Bert (a/k/a "Santa Claus") as a regular flyer at the NCR launches. Sue lost a brave fight to can...

No worries. The PerfectFlite guy (Peter) printed his circuit boards before he got my comments... that is why the boards don't show the 24 seconds but the manual does. That is a is a decent little alt...

Scott, there is a 24 second mach delay.... Go to and scroll down to page 8 of the manual (which is page 11 of the downloaded .pdf) You lay the jumper horizontally across J3 and J4 on the pins close...

Could be the new galactic headquarters for 3 Dogs Rocketry!!! 8) That is awesome you did that Mike - Very nice thing to put up there for others to use.

We had a very severe storm come through Windsor and it headed exactly at the N site. There were several funnel clouds up around Nunn. The rain was intense, I sure would not be surprised if an inch f...

Sean, I would sure suggest you hang a note on the tower asking / suggesting / requiring folks to come see you before they tweak away. I had a tower a few years ago that was pretty well ravaged by the...

Invite the kids to our next launch 8) our own fire department!
