I like that--and imagine I'd be more inclined to watch blinks than try to listen to beeps. Looking forward to it becoming available!

Good luck to you, Bill!

Ground test. You'd be surprised what charges cardboard can handle. The Info Central calculator: http://www.info-central.org/?article=303 gives you good starting points for ground testing.

Sounds like a job for a kid. They make 'em with little arms and hands so they can reach into airframes... heheh

Bioptical sensoring works well enough for me, most of the time. If I need a handy guide while doing so, I've got a laser level which can project a straight red line. Never ran into any project...

Well done! Congratulations!

I must say, I dig the conduits-- look forward to more photos of the flight!

Put the data and speculation away right now. Go to the prom, and make memories. I commend you not only on the attempt, but on the way you've handled it. Well done. Inspirationally well done.

I would very much like to see the video, once you do this...

I don't think there's anyone that'd mistake a CTI motor for any other: they've got too many distinctive features to be confused with anything else.

My understanding was that Canadian L2 not only permits I's, but also hybrids. Is that correct?

Do they have a specified cert level for Ex motors?

Honestly, if you're already owning a 3-grain case, and are going to take advantage of the case offer for certification flight, may as well go to the 6 or 6XL.

Finished repairing DB's Upscale Hornet and applied TQOTU's Mega Der Pink Max replacement sticker --Thanks, Mark!-- also, built the av-bay (sans electronics, at current) for the upscale Phoenix Bird...

I use JB weld. It's easy to squeeze out equal sized lines on a paper plate, smudge 'em till grey with a balsa scrap and apply. And it handles heat, too--which is good. If 30 min epoxy were as easy...

Congratulations! Nice flight, there!

I have a pair of Mega Der (Blue/Pink) Maxes that've both flown on G's fairly well. Both came in at around 1,100 grams. G-106's to ~1,000 ish feet.

Sounds like you want a longer-burning motor, not necessarily a higher impulse. Could you post a Rocksim file?

Any substantial HPR rocket, given a flight anomaly (weak motor ejection, failed parachute, whatever), could damage a vehicle or hurt someone coming in from altitude. That's always a risk--albeit a...

Is this for a planned cert flight?

Cut The Queen of the Universe's Mega Pink Max's zipper out, got replacement BT section sized and primered. Also got the Hornet's replacement fin attached. Once the repairs are complete, going to...

I think this will be the year of altimeter proliferation here at Cooper Kitchen Tech. Heh. I cannibalized the Goblin to fly my son's Hornet, felt dirty doing it. Wanted to grab a couple of Adept...

Direct hobby-related injuries are mostly going to be minor abrasions and lacs with a side order of punctures received in the build process. Flight-line injuries/maladies are going to be primarily...

Yes. Sorry.

Ari was working on something a while ago with break-apart recovery, but I don't recall hearing a flight report --the airframe broke into several tethered sections like this. He was using...

In thinking about it, the goals didn't start coming until I had the certification. L1 goal was to get basic build techniques down. I figured I was ready for L2, so I incorporated all I'd learned up...

Make it out of something a bit more formable than paper?

I'm not sure I understand what you're asking. The payload section is routinely pinned to the av-bay. Sure, you could use screws to hold the pieces together if you wanted to. But why would you want...

If I need a custom NC for a particular build, I call the Sandman at www.roachwerksmachining.com. I figure he's forgotten more about making NCs than I ever learned. He's made a few for me (4" Red...

Model rocket--that is, less than 1.5kg and using G motors or smaller? Have at it... safely. That's how high.
