Bruce,

The last of my flights listed (9/11) did have gps at apogee. It was over 100K, but not by a lot. I'd have to dig to find the actual number.

The flight listed on 9/15 as 130,570 feet.

The flight listed on 9/21/18 didn't have gps at apogee, but it did have gps at 160K both going up and coming down. The 175K apogee was estimated from the attached graph.

Thanks Jim! I was curious about the CarbYen names. Is there a story behind them? And can you explain a bit about your stabilization system?

Mostly, I'm just not very good naming rockets. I had a shred a few years back and decided I needed to build stronger rockets. You could say I had a yen for carbon. The low carb diet was popular at the time, thus, the first in the series was the LowCarbYen. It just went from there.

Here's a flight video that has some information on the stabilization system. We keep making improvements and it works quite well. More videos can be found on my "page" (search jiminaus50).

USC RPL Traveler IV
EX R motor
90% confident 320,000'

The video left me with questions...

What is 90% confident? Was this a simulation prediction? Or did they get GPS data up to a certain point and the apogee was extrapolated? If that certain point was the 160,000 foot COCOM limit, then it could be a significant extrapolation.

Thanks Tony! Might you be able to tell us how the rocket got the name Mr. Fish Business?

Any new high altitude projects in the works?

Luckily for you they wrote a 24 page report on that exact subject. The answers to your questions are contained within.

Here's the report

@Bruce both of my 100k+ flights used a CTI N2500 in the booster. Both flights were with the same rocket. The second flight hit 154k with updates to the launch pad and it was pretty hot day too (90F). I did try a CTI N2501 a couple times but had no-lights on the sustainer.

I am building a new project 4.5” O4500 (28k Ns) to a 3” M800 (8k Ns). It will be ready for summer of 2022. Expected altitude is ~225k.

Thanks Kip! Your next project sounds interesting. Can you tell us if you'll be able to have a non-COCOM limited GPS onboard?

OK, here's a list of the 100,000 foot Rocket Flights known so far.

The first group is individual flights with the altitude recorded by GPS.

The second group is flights where the altitude was not recorded by GPS or the rocket was built by a team.

7/18 Kip Daugirdas - ~154,000ft, N2501 / M685
9/16 Kip Daugirdas - ~145,000ft, N2500 / M685
9/21/19 Jim Jarvis - 142,109 ft, P8535 / O6061
9/15 Jim Jarvis 3 stage - ~130,000ft
9/20/14 Neil Anderson Money Pit - 118,638 ft, N5800 / N1560, 36,949NS, 105 lbs
9/20/13 Jim Jarvis FourCarbYen - ~118,632ft, N5800 / N1100,

07/14/14 Ky Michaelson CSXT Go Fast - 385,800 ft, team project
9/21/18 Jim Jarvis ThreeCarbYen - ~175,000ft, no apogee GPS data
9/30/11 Derek Deville Qu8k - ~121,000 ft, Q18,000, 143,000NS, 320 lbs, no GPS data
9/11/12 Ken Biba AeroPac - 104,659 ft, N1000W / M685W, 21,650NS, 61 lbs, team project
9/11 Jim Jarvis - ~100,000ft, N5800 / N1100, no GPS data

Let me know needed additions and / or corrections. More data such as the rocket's name, weight, exact date and altitude would be most welcome.
Just that list is impressive, not to mention others that will turn up. I guess I need to set some goals in rocketry once life settles down.

Seems like ALOT of 2 stage rockets... getting the second stage to light.. ya, I'd be a bit nervous

Great stuff !!

Hey, don't forget the three-stage rockets! And yes, in my two three-stage projects that are listed, the second and third stage motors for both flights were recycled from the previous year. Sigh....

Please correct me if I'm wrong, but it appears COCOM ceased to function in on 31 March 1994. Given that maybe we should not use that terminology anymore? It appears that the Wassenaar Arrangement is now the new thing?
The US included most GPS hardware on its munitions list but removed it a few years back. That was the source of the altitude or velocity limit. That applied to exports but the limits were included in nearly all GPS receivers.

So now rather than ITAR there are State Department rules to deal with.

Yes. And that change is what allows an unlimited altitude capability for commercial GPS units. There is only a 600 m/s velocity limit now.
