Yes Bret. Drill some 1/4" or 3/8" holes in the bulkhead.

Well, if not an eyebolt in the motor case, my other choice would be to build the booster section zipperless and install the eyebolt in the forward bulkhead.

Exactly what I'm talking about - except that I wrap the packets in different # of layers - one packet with one layer, then 2, then 3, etc. That way they pull apart in the order I want to prevent tangl...

Congrats Daddy....

Personally I'm a masking tape Z-fold guy...1 layer where I want it to break first, then 2, then 3, then 4... in 4 bundles. Has worked well so far. I use masking tape because it is cheap and biodegrada...

12 grams may seem excessive on a 6" airframe, but it depends on the length of the bay and as I recall Conway's bird was a bit long. The UprOar project, a 7.5" project with an inner airframe of 6"" and...

I got 90 degree SMA connectors at JB Saunders in Boulder - I think they were $1.50 or something like that.

Wilke still uses the free version of Rocksim 4.0 I think.

At least with Rocksim 7.x I've seen that the manual optimization works far better than the automatic. Rocksim 8 (paid for) doesn't work on any of my systems at all.

Ah Bruce - you should place credit where credit is due. The altitude king of NCR is John Wilke and I have borrowed more ideas from him than I could list. Of course I've liberally borrowed wherever I f...

Most rockets aren't complicated at all. People leave tons of space in their designs to fit things like shock cords and chutes and electronics. Where things start getting interesting is trying to fit e...

Looks cool. I expect it would be quite heavy compared to an equivalent composite or paper/phenolic rocket.

To each their own I sez... For my L3, I wanted to avoid the hubris I had going into my L2 cert process which ended up causing the loss or destruction of 4 birds before I successfully certed. As it was...

Sounds like one of my L2 attempts Sean... I wanted to tickle our 20K waiver. Whatever happened, it is still out there on the prairie somewhere - probably 8' down. Lots of people told me not to get com...

I've seen carbon tubes fly that were a single wrap of 5.7oz fabric. You could nearly flatten it with your fingers, but it was rigid enough for an H motor. It is a matter of what you're trying to do. I...
