Re: Joe Turners L2 Build Thread

Hi OTT, I did a few sims and I found that Open Rocket raised an alarm with smaller Drogue Chutes. It says "Recovery Device Deployment at High Speed"- which I think it means when the Main Chute is ejected. e.g. for 18" - roughly 29ms-1 When I put in larger Drogue Chutes, the warning w...

Re: More Star Wars Madness

How would put fins on it while keepin the same look? Back end looks pretty big and draggy. Think about how it compares to things like saucer and pyramid odd-rocs. RS and OR are not likely to give believable results for simulations. If I were building it, I would build it as is, load motors, and do ...

Re: SpaceX SES-11 Launch

Nice job SpaceX. Gotta say that one looked extra toasty on re-entry, both grid fins fully glowing and something appeared to be being cooked at the business end then the single cut out. Won't be supprised if this one gets retired.

Re: SpaceX Goes All In On The Big Freaking Rocket

Good video. His new plan is definitely a better solution then the last, still thinking financial funding is going to be difficult.

Re: Joe Turners L2 Build Thread

I think your over doing it. I would not go with the assumption that it won't vent. I this is causing to over do the pins and then to over compensate with bigger BP charges. End result high energy deployment. You'll then need to make sure that you use extra long recovery harness. With a reasonable si...

How would put fins on it while keepin the same look? Other issue I see is all the weight will be a the back, especially once you load 11 motors.

More Star Wars Madness

First up I'm looking for feedback on what to build, with the help of my son we came up with three possibiliti...

Re: L2 Attempt Launch 2018 Questions

In response to you questions: I have a few questions regarding the form. Hoping someone might be able to help. 1."Have you been assessed as competent in the use of explosives within the past 5 years". I assume this is more for Shotfirerers...but I'm ticking "NO". No sure about th...
