Ostensibly the one rocket I came to launch was the recently built Sublime by Rocketry Warehouse and designed by Gary Tortora who is active here on TRF. Fretted most of Saturday worrying the parachute bundle was too long and the 3.5 grams of BP in the motor would not pressurize the long tubing and the large transition.
Oh and did I mention it fell over cracking loose the epoxy on the lower transition shoulder?? :surprised::sad::bangpan::bangpan:
Well it was clean so I just sanded it back down thoroughly, and used a bunch of 15 minute epoxy and let it set. It was fine. My pride was more damaged than the rocket. I felt bad because a few people came to see it fly...
But as it turns out, I grew a pair :lol: and hauled it out to a far pad for the "Sunday Morning Wake Up Launch".
Yes I was still nervous... a lot... I had never bundled a chute that big (a Rocketman 84" (2.1m) in a 4" (10cm) tube)
I love it. Most people who saw it do. I think RW may sell a few more though most people seemed to want a 75mm mount. I sure they can get that if the Sim shows it stable.
Here it sits. In the nose is a Stratologger doing the tie wrap cutting via a (what else!) Archetype Cable Cutter. In the bottom is a CTI 1281-K360 cut to a 10 second delay. (That's right, 1ns over a 100% J) The 2 grams of BP in the K360 was supplemented by another 1.5 grams poured on top of the cap and taped over.
Ok everyone... wake up!
Closer crop:
It powered it's way on up to 2521' (768m).
All my fretting was for naught. The chute bundle ejected almost at apogee (certainly as it was arcing over) perfectly. HOWEVER... the main got loose and deployed right there and then! Well drats. That chute material is REALLY slippery and the burrito protector covered about 80% of the chute (bottom completely covered of course).
So I'll have to create a bigger protector that maybe I can tuck in both bottom and top... or something... anyways it was a gorgeous flight and safe. Just a really LONG walk (damn that 5* :wink. Oh and the cutter? :lol: it worked perfectly. I saw it go off and sure enough the tie wrap was severed. Oh well...
