Cool. Is it coming back? As in, gonna fly?
Cool, love to see it actually happen. Can you give us any info on the motor itself? Understand if that's gotta be held tight for now..
What are your plans for electronics?

Well yesterday was a good day.
The reason I backed off the project was the R motor. Pat G smartly stepped back due to his plate (as always) being full and then some. I realized I don't have the years of practice needed to build and test successive motors on up to an R.
Yesterday a couple of very experienced rocket motor guys came to the house. They are on the road right now and I don't have permission to give names. However after a lengthy discussion yesterday it became obvious that they are quite capable of producing the R motor needed for this rocket. One of them can't actually build due to other aerospace agreements but one of them if given time certainly has the skills to produce up to a mid R motor.
The plan will be for me to transfer the 10' motor casings, liners and casting sleeves to this gentleman.
BALLS 2020 is the immediate goal. The motor builder will provide full support meaning he shows up at BALLS with the R motor after full approval through the Tripoli C3RC review process. After the flight he takes the casing back for cleaning and prep for a future launch.
A man must know his limitations and I know mine. I can build a great rocket especially with engineers (and many of you!) providing input and corrections. However I don't have the required knowledge of propellant formulation and actual mixing to do the motor on my own. I don't (yet) have the ability to converse with the C3RC team on motor formulations with enough knowledge to get the proper approvals. The C3RC takes this stuff very serious as they should.
However with an expert motor builder I know we can get through the C3RC process correctly. The rocket is solid and I'm looking forward to getting it through the C3RC.
The only things I sold that need to be replaced are the electronics and the recovery harness. Easy to do in the months ahead.
If this rocket and motor flies successfully we will then look at a 16" G-12 airframed rocket with an S motor.
I've learned a great deal in the past year and will continue to do so.
This is an AWESOME thread and for the first time a very big rocket was built from scratch using inputs of dozens of you. Trust me there are many old-timers out there who haven't approved of my approach. I respect their discontent however I also know a team approach produces superior results 100% of the time. There's a reason the airlines, shipping, railroads, hospitals and many other fields are utilizing a team approach to the decision-making process. As an airline Captain trust me the past three decades have drastically changed how I arrive at the smartest decisions especially when hundreds of lives are in the balance.
So we move forward with strength! As always I'm open to ideas and corrections. I don't know it all. But there is a 22' foot rocket sitting on a world-class launch trailer built by THE Levi Seaton that is aching to stretch it's legs. It's exciting to know a new path has opened for this to happen.
Merry Christmas everyone!

Yes it's not going to be a "showy" motor. It's going to be designed using modern methods for producing the most power. Using these methods a 10' casing should be able to produce upwards of a mid-R.

Yes it’s gonna soar....
Funny seeing the ' in lieu of the " when referecing motors.Yes it's not going to be a "showy" motor. It's going to be designed using modern methods for producing the most power. Using these methods a 10' casing should be able to produce upwards of a mid-R.

If the rocket doesn’t exceed current flutter Mach after new motor data is collected I don’t see a need to sim it again. However if another flutter sim is needed I still have access to finsim v4.53.
If this rocket and motor flies successfully we will then look at a 16" G-12 airframed rocket with an S motor.

That's not the "real deal" but something Curtis Turner made. I'd worry about aerodynamic heating at the velocities that are expected. May not have an intact NC into or after the planned flight. KurtChuck,
I think I might have found your Nose Cone for the "S" Motor . . .
