ROCstock was absolutely awesome! I got far too much flying done over the course of the 3-day event to do a play-by-play report, but here is a quick summary:
  • My Super Gnome made five flights: three successful flights in two-stage configuration, along with one successful flight in a single-stage configuration and an unsuccessful two-stage flight in which the sustainer failed to light. This rocket attracted some attention from a few attendees who had seen it here on TRF and wanted more information on how I made it and how it works.
  • My rebuilt Phantom made all of its six flights with a cardstock liner inserted in the body tube to preserve its transparency. This included my first ever night flight, with a blinky installed in the nose. This flight was the one that did it in; I have since replaced it with an Estes Generic E2X, although I’ve held onto the nose and blinky just in case I ever want to do a night flight on that one.
  • I intended to enter my stock Estes Goblin reissue in the contest for Goblin derivatives, clones, and upscales. The guy at the check-in booth just laughed at me. I think it ended up flying three times through the event, ending its weekend with a tangled chute and two cracked fins.
  • My Hi-Flier XL made two successful flights on the reinstalled motor mount, but while I was loading it up for a third flight, the forward centering ring failed from damage sustained during its splashdown at Fiesta Island last month. I purchased a new mount kit from Discount Rocketry and I plan to install it soon.
  • My Star Orbiter made not one but TWO successful flights on E23s, my first flights with any kind of reloadable. I have since cleaned out the hardware and ordered Aerotech E16W reloads through AMW.
  • I tried my hand at working the launch control system and PA system, hitting the button for rockets up to M power and helping a couple of flyers make their certification flights.
Overall, fun weekend. I look forward to joining ROC in the future, that was a great event. I take my hat off to all of those who made that possible.

He laughed because of its condition?

It’s small! The other entries were upscales that flew on J and K motors, mine is just the normal size with a 24x70mm mount. I’m not sure what the parameters of the contest were, but I think they were going for altitude.

Those were some pretty awesome flights! I loved the speed on the sustainer. Glad you enjoyed ROC! Now what about a 3 stage gnome......

I’m glad you enjoyed the Super Gnome! 😁

I, too, was surprised see the thing really kick when it staged. The 1/2A has a surprising amount of initial thrust when you consider how small it is.
Now what about a 3 stage gnome......

I got exactly that question from another attendee. It’s doable but I don’t think I want that kind of complexity and difficult of recovery in that configuration. Rocksim also indicated that stability gets tricky with additional stages. Three looked fine but I wouldn’t want to go for four without an enlarged custom fin unit. I’d love to see somebody else build on what I have done though, I don’t see a whole lot of multi-staging at this scale.
