It was a very nice day at the North site. There was a cert or two, and some notable flights.
Sean Serell flew a G-to-G on a nice boost that claimed a Tripoli 2 stage record of 9,200′. IIRC Sean said he had a 12 second delay on lighting the second stage. It was *very* cool.
Hats off to Adrian Adamson who had a MONSTER boost on an I600 to over 16K. Unfortunately the rocket came in hot, but the altimeter was beeping away. It was an utterly straight, energetic, outstanding boost. Incredible shot Adrian!

Yes it was. Great weather and Great People.
Here are some pictures.
There is one pic. of a lost and found piece of electronics.
What is it? Or was it. If it is Yours, You sure can have it.Adrian

Thanks, John. You had some very sweet looking Performance rockets today.
Congratulations, Sean. Even though it’s the first record, I bet it will last awhile.
Here is a quick Youtube of the liftoff. Thanks to Sean for shooting the video with my camera. The flight was 2:37, so if it took 30 seconds to apogee, it averaged 87 mph on the way down from 16,379.

Both charges went off, and the apogee charge did its job, but my friction fit to hold the main in was too tight, so it never came out:

Just as an FYI, NCR does not have the capability of tracking records for anything other than single motor, single stage, non-clustered rockets at this time. While we would like to do so, we do not currently have the programming resources to expand the altitude record application within the website to accomodate that. Until a new programmer steps forward to assist with this, I can offer no timetable for this upgrade to our website’s capability.
Tripoli does and I highly recommend you apply to the TRA Altitude Record committee for the record.

Yep, we signed off on Sean’s record and got the paperwork headed to TRA. My hunch is Adrian will be back at the drawing board for the I boost as well.
One of the odd (but good) challenges for altitude geeks now is that so many new motors are being certified, it is hard to commit to building a rocket because by the time you get it done, there will probably be new motors out that will be more suited for your project — and they may not fit the rocket you just built.
I think I’ll start on a K project, size it for the K350, and cut it back if/when new and better motors come out. This is a great problem to have 8)

Great pictures, looks like everyone had a blast. Didnt have the Aspire done yet, so decide to work and do some catch up here around the house. That giving me 2 more weeks to get her finished. Hopefully she just got her finally coat of primer, little sanding, then some color. It was very helpful getting to see the pictures, made me think of several other things that would be nice to bring, CHAIR and table maybe. oh yeah and a shade tree, hehe, j/k.
did make me a 15 volt power source box, light weight. Although looked like you guys had that all under contol. Haven’t even got to use the new launch pad and set up, just did igniter test. Not a one black mark yetaAgain great pictures!

Yep great day! I wanted to thank John especially for loaning me his tracker which was definitely required. I had a nice shot on a 29mm G to G (I designed this rocket on H to H but the casings I needed didn’t arrive so I stepped it down). Hopefully I can get it launched with the H to H before Adrian gets time to work on a staged project (thanks for letting me use your tower as well!). -Sean

I built one of those!
Dont spend to much time finishing it!
If you see it come back, it tail lands….. with a streamer…..damage 😕
If you dont….. well…. you dont……… 🙄Chad
Good point about the streamer. Our launch sites have so much space, there is incentive to use a parachute to slow it down to <30 fps. I've got a custom 8.5" X-type parachute, and the readily available 10" X-type would probably be just fine too. Do you have RockSim to get an estimated decent rate?
Then again, there is so much tall grass out on the prairie, you just might have a nice soft landing.

Tall grass yess.
My Pawnee Arrow fell from 6000′ or so on a 36″ drogue.
A 5″ by 7′ duel deploy. It only broke a 4″ piece just below
the nose cone. I was pretty amazed.Right now the grass is pretty forgiving.
