After watching the latest Spacex news, I began wondering; Like we do with motor classifications beyond S, what would some hypothetical certifications be beyond Level 3? What level cert would Elon Musk be, if it went that far? For example: Level 4 = 100,000 ft altitude Level 5 = Karman line...

Has anyone heard of or tried Brave? I'm really impressed by it and it seems fast. Also has built-in ad blocking if you're into that thing. I was watching YouTube the other day with the Brave browser and realized I hadn't seen any ads.... at all.

It's about time for another scratch build. This time I'm going to try and build a model of the Falcon Heavy. I put together a model of one in OR as a test case for debugging a while back. Out of curiosity, I measured the dimensions of a Falcon 9 booster and lo and behold, it's nearly an exact...

I'm asking out of curiosity, as a way to gauge the interest in alternate pre-defined nose cone shapes for the next-next OR release? I know it's something that some devs have been working on - as in the rounded tips that we seem to add anyway. But what about the HoJo/Expedition(with details), or...

I finally got(yanked) my Cosmic Interceptor out of a tree this last weekend. The chute and nose come are still there and will probably be there for a long time. It's been up there since March 20th, so nearly 4 months of Ontario snow, wind and rain. So what happens? This is what happens. At...

What is the current status of MASA? Still very active? I'm going to be spending a significant amount of time in Minnesota this year. I'll be in the Metro area mostly. I see they just had a launch on the 3rd. Nothing on the website calendar though. Is there a long-term schedule of sorts? Is it a...

What is the best method for repairing clear fins? My Falcon 9 took a hard landing and broke one fin, cracked another. I was thinking of trying plastic cement however I'm not sure if that will hold. I'm not really sure what material this is. Clear plastic/polycarbonate/acrylic? Perhaps a small...

I have a 2.6" rocket weighing about 29oz with a 38mm motor mount that I'll be bringing to NYPOWER in a couple weeks. I would like to take advantage of the large field and really put it up there, but I don't have any kind of tracking device currently other than a pair of binoculars... It will be...

I picked up these two 120deg 720p 808s (guts only) with the idea of doing a stereo onboard launch video. :cool: The idea was easier than the implementation as I've been trying to figure out the best way of accomplishing this setup for a 3" airframe. Here are the two cams that I have Using...

Here for your consideration is a model that I've tinkered with for a while. Seems like it would be a cool build although I have no idea what I would do about decals. Paper wrap perhaps? The main body tube is an Estes PSII 3" body tube, the S-IVB stage is 2", and the service module is a 29mm...

Magnum time again! I wanted to build another Magnum but this time a upscale. The hard part of upscaling this model is finding a 5:1 ogive nose cone. I found a BT-80 and a BT-70 one. If I went with a 2.6" airframe then it would have been heavy enough to need composites and staging composites is...

We've all heard of references to how many millions of horsepower the Saturn V or Shuttle engines produce(as a way to relate to the public). Out of sheer curiosity, how would our rocket motors be rated in horsepower? What exactly would the formula be? I found a series of conversion calculators...

Can anyone provide or verify the measurements in this OpenRocket file? It's the plastic nose block that came with the Estes Magnum #1422/2032, and possibly other kits?. I'm working on creating an .stl file to go along with this so it can be brought back to life via 3D printing. Also if anyone...

I'm trying to decide what to do for a chute for my 2.5" Javelin. I could order another 24" chute more suited to HPR but I have a couple extra 24" Estes nylon chutes sitting here and would like to use them somewhere. I've been wondering: What would need to be done to beef them up for HPR...

Upon the prompting by the OpenRocket Ninja himself, I was reminded that I have quite a few OR files that would be better shared than just sitting on a thumb drive somewhere. Good way to have a backup as well. I may include the occasional custom design if it's been flight-proven. I've tried to...

The Estes Javelin (#2005) was another one of my favorites from the 80's. After tinkering with an upscaled design here, I finally decided to start with a PSII Panavia and modify it a bit. Swap in a 38mm motor mount, glass the body tubes, set aside the Panavia fins and cut some 1/4" ply fins...

While I was at my LHS on lunch today, I was picking up some fiberglass sheets and epoxy for my first attempt at glassing a tube and asked the guys there about what they recommend. The first suggestion was vacuum-bagging, then the "peel-ply" technique, but he also mentioned that I could apply...

Those of us north of the border know all too well the frustration of outrageous shipping costs when ordering from US sites... Checking what's new at one of my favorite rocketry supplies websites(www.allrocketengines.ca), I noticed they have a gaggle of Semroc kits available! :surprised: Orbital...

Holy cow! It's been 1 year now since launching my son's Estes Taser on an A8-3 brought me back into rocketry as a BAR. One year ago: I didn't know anyone other than Estes made rockets. I didn't know there was anything other than BP motors made by Estes. I didn't know there was such a thing as...

I'd like to try building my own pad with a 1010 rail. I've been looking around, maybe I'm not looking enough, but I can't seem to find a local source for a 6' 1010 rail beam. I would prefer to pick up a rail beam locally(GTA) rather than have it shipped if at all possible. I can find them on...
