The Carbon Daddy...

Nosecone still go on? It's hard to tell from the photo.

It does. With a little room for NC weight.

Maybe I'll build me a Big Daddy with a red nose cone and fins, and cover the BT with CF pattern Monokote.
Yours looks great!

Don't cheat! I might be able to make you a tube some time. I have a little left over CF and extra BT.

Did I miss what you did for retention? Has this flown yet?

[Aksrockets]

Nope, Hasn't flown quite yet. I'm running a little short on money for 54mm motors this year, but I am planning on selling some stuff. Hopefully that'll balance out the budget a little better. I want to fly this at LDRS on the J1055 Vmax. I've also got a 1G 38mm motor in my motor box.

Retention is just a friction fit and masking tape.

Friction fit? You are a braver man than I, sir!

People (I have) have flown N motors (and bigger-not me) in 70 pound rockets with friction fit. Its really nothing to be afraid of.

I prefer positive retention in all sizes of my rockets. One less thing for me to worry about.

I'm with you, I hate to lose a $30 casing much less a $200 one. I know I would feel horrible if a rocket I launched kicked a motor that conked somebody on the head.

Shock cord attached to the forward bulkhead of the motor pretty much assures that will not happen. Don't get me wrong. I use Aeropak retainers whenever possible. Some applications do not allow (minimum diameter).

Aeropack has a device for minimum diameter retention.

Or broke somebody's windshield.

I have used them and like them.

little short on money

Really? A LITTLE? Really?

Well, Since I left a good portion of the aft MMT tube exposed, I can get a good amount of tape wrapped around there and since I have access to the front of the MMT tube as well, I can wrap tape around the front of the motor to the front of the motor tube. I've friction fitted almost every HPR motor I've flown without a problem.
