Fins sanded and fit,  aeropoxy ES6209 spread into the slots, then fins buttered and hammered into place.   Nice tight fit and stayed in place, so no fin guides.  Lined them up by eye to a printed template.   Right about 14" from the end of each fin to the next.  works for me.













I'm really liking this size rocket.  Large, but still very manageable.  Should fly on a fairly wide range of motors too. 

Next up is the ever exciting injection of fillets.  planning on ten grams of aeropoxy for each fillet, half in each hole.

After that, externals of proline 4500.

Injected 20 ml of aeropoxy into each side.  5ml a hole in rotation so it could run out a bit in between injections.  Then I taped the holes.





At first it piled up in two globs.  after a few minutes, it had ran out fairly well.

Work has progressed, I've been lazy on updates so here we go

Aeopoxy poured over the top of the retainer.  It's not coming off...so lets make sure it's never coming off.


Look what I picked up at URRF.....



I also decided it was going to need a new cone, the old gelcoat was a mess.


Fillet locations sanded and marked out-













When I'm taping and pulling and mixing multiple batches, I find it easier to just keep a box nearby to toss everything in-

In primer.

I'm using a 3M sanding sponge to very ver very lightly sand the rough off the primer.

Dave, remind me please, NAR or TRA L3? I've been following along with the whole Build process and you've been doing a beautiful job. Just let me ask please, can you give me at least a weeks notice that you are going to go for your cert flight. I didn't know that you were planning on trying in September until the Monday after, this way we can make sure that I haven't planned anything else and can be there for you. Like for this October Launch, I already have two L3 Certs to do and Sunday is my 24 wedding anniversary and I plan to leave by 1 PM to go take Linda to dinner.
So it would help if a head of time that I knew that you were planning on trying for a certain launch.
Thanks, Dutch

Thanks for the comments, it's been a long build but fun.

It'll be TRA.   I'll certainly give at least a week or two notice.  I'd taken the whole weekend off in sept, but right when I was about to make the call to fly or not, my daughter had some minor surgery scheduled and I decided to put it off.   

I'm done flying for this year, so I'm going to spend the winter working on this avbay, but the rocket is essentially finished.

OK so since your going through Tripoli, you will need two TAP's to approve your build. Can you put together a proposal so we can send it off to Jim Livingston so he can be your second TAP. Jim comes up from SC every year to his house on Conesus Lake every summer. he is a club member and comes to the launches and flies with us while he's here but I don't think he is on the club forum. You only need one TAP to witness the flight but two have to sign off on the build.
I can give you Jim's Email and Phone number but not on a public forum. Let me know if you would like to contact him.

Yep I'll amend the proposal and make sure it's up to date, and get a copy to you and Jim. 

I've got the nose buttoned up, no glue so I can make a bay of it later if desired. 



And a splash of color-

11.5 Lbs !!!  And an M motor !!!  In this state? LOL.

 This is a BALLS Project and I want to be there. It will go like hell or shred.
Knowing you it go like hell. Cool.
I hope your NOT using rocket sim. There predictions over Mach don't do well.

LOL, thanks Paul.... it should be fun :)   

I used Rocksim for CP and CG (measured against actual) and fired the M2550LB at it in there.   Also fed everything through rasaero and the numbers actually weren't far off rocksim.   I'm going to rebuild both sim files from the ground up over the winter to double check it all, but looking around 16,000' and mach 1.5

This thing looks awesome! the light weight will help keep it under the waiver. I've had really good results with open rocket over mach, a few flights right around mach 1.5. good stability results and good speed/altitude results. The only challenge I've had is with stubby rockets and boat tails.
