I’ll talk with Jeremiah about it. I can arrange hosting for you for $10/mo or thereabouts.Warren

I would’ve bet my lunch regular phenolic would have shred. I’m quite impressed / surprised that it did not. Seems like years ago I read in PML’s FAQ that 38mm and 29mm would survive pretty much anything, but you should…   Read more»

Adrian, by my calculation, 15 oz. was under optimal mass — but not by much. 15-18 oz. (in my sims) all came w/in 50′ or so of each other. The top of the curve is pretty flat. Even jumping up…   Read more»

Chris,How did your Cirrus mass compare with the optimal mass for that motor?

Chris, that was an extraordinary blast. I always thought my “I” record was the safest one I had, thanks for the wakeup call ;-)15 oz. is very light. When you say “stock finish” does that mean you did not glass…   Read more»

My Cirrus Dart was the first HPR bird I built and I wrapped three full wraps of 6oz glass around that baby. It flew successfully a three times and the forth flight was a spur of the moment attempt at…   Read more»

Yep – 11,950. It was an absolutely gorgeous flight, and the flame out of the I600 was probably as long as the rocket. I also got incredibly lucky with the wind – it would have been incredibly easy for that…   Read more»

His Cirrus Dart went about 11,950′. There was very little wind, he launched from a tower and it was plenty hot. Also note that he used an electronic timer for deployment; this rocket and motor combination would likely shred with…   Read more»

IIRC Chris did just under 12K – he flew it with one of Adrian’s Parrots. He was flying the I600, I believe.I flew an I132 to 12,136′. I sure wish I had used that motor in an optimized bird 8O…   Read more»

I may be mis-remembering things. Perhaps Chris only did 11K+ on his I600. On checking my flight records, my flight was on a 5 grain Cesaroni J285, not an I.Warren

John, we don’t keep club records by rocket or by design… we keep them by impulse class. The club J record is a snitch over 17K. That was on a J570, and it was recovered intact.

I concur with Edward – one of the acknowledge hybrid experts of the club. Any hybrid except the Hypertek should be ignitable by a plain ematch – at least any that use an AP slug or pyrodex pellet. The Hyperteks…   Read more»

I’d use a regular e-match to light the motor. If you look you’ll see the supplied igniter is just a resistor that needs 24v to heat up and get the motor going. Swap that out for an e-match and then…   Read more»

the contrail is very similar to SR and RATT, the floating valve. but as he said their system is a 24v system.
