Finally got to test fire my 98/20480 (not a typo - Rx case) N1030.
That was a nice long burn!

Dude. Wow.Just pulled this of my 3D printer. A Nike Smoke translucent fin can.

That was a nice long burn!
The N800 burns 17 seconds, with the stepped core on this one, probably a little longer. Haven't counted frames yet.Wow what is the burn time on that one?
stepped core

The motor is a D grain. Cast a solid stick and slice off the side. Most of the grain has a 2.4" wide flat, the last 13" has a 2.8" wide flat. (Area of port is equivalent to 1" and 1.5" round cores respectively.) The N800 is 2.4" all the way. Both motors have a short U shaped booster grain to increase liftoff thrust."stepped core" I have not seen that one. Off-set core moonburner is the only long burner I have seen. I am assuming this is not commercial and specific to EX?
The only temp indicator is a piece of masking tape on the side of the case where the port is located. (This also helps when installing the starter.) No discoloration of the tape and I have used the same case 7 times for N800s (RMS 98/15360) with no problems.Nice burn. I have a question for you- did you measure the case temperature during the burn? Thermocouple of some other method. Burning that long that has got to get hot.
Sounds very interesting. I don't want to cross the line into the research forum so I will refrain from soliciting more details, even though I am curious.The motor is a D grain.

Finally finished a scratch build that’s been on the drawing board since August, an experimental mid-size (A-C) canard designed and built during spare moments and between other builds. Just wanted to see if a glider newbie like me could actually get something airworthy and flyable out of everything I’ve been reading.
Why a canard? Because they’re harder to get right than “normal” gliders, so crafting something that successfully flies well is so much more satisfying. Besides, “tail first” is so much cooler IMHO.
Length 18.75” | Wingspan: 17” | Weight: 1oz

2nd pic is the cardboard prototype that I fine-tuned canard and rudder sizes with.

(Apologies for the full size pics, "attach thumbnail" wouldn't work).
Those parts, paired with a Mach1 Rocketry BT-60 tube. Thier super thin wall fiberglass is just as translucent. Would make a great night flight rocket.Hot off the printer..... because the translucent fin can turned out great I thought I would add a nose cone as well. Next probable print... translucent launch lugs

Received my explosives license today, so I can now legally take HPR motors and buy/take home BP home with me!
I’m off to try to find some FFFF tomorrow. I’m sure it will be complicated and weird (I’ve NEVER even entered a firearm store before).

Just don't bring up the first clause of the second amendment... oh, right. Australia. Congratulations on the license.
