I have a 29/360 Aerotech case and the closures I need to sell off due. Lost my job so I’m selling all my unneeded stuff. $40 shipped takes it. Doesn’t have a seal disk.

I'm starting a thread for Launch Pad rocket plans to be uploaded and shared. These rockets are too unique and beautiful to not be shared with current or future builders who enjoy scratch building and challenges and there should be no reason to not have a "Plan Repository" for these kits . I have...

I'm working on a half scale Arcturus rocket and the ARC nose cones are secant ogives and not tangent ogive. I'm using FreeCAD to try and make a nose cone in their workbench but from what I've gathered on the difference between the two ogives, the one in FreeCAD is a tangent ogive. Would someone...

Those that have built the larger Boyce Nike Hercules, where did you put the rail guides? If I attach them where the instructions claim they go, the lower one sits higher than the upper one and I think that won’t work.

So last August I acquired two free rockets, one being a PML 2" AMRAAM and the other was a rocket I couldn't identify. It looked similar to a DX3 and the PML Intruder but not quite. I scoured the web for a few days and came across a picture (the only picture and mention) of a North Coast Tempest...

Does the drag from tube fins change depending on if the tube is not square on the ends? The Pemberton King Kraken has non-straight tube fin ends so would it have the same amount of drag as if it didn’t have cut tubes or would it have the same amount of drag as a wood fin in the same shape...

Working on an Aerotech Astrobee-D and I'm confused by the instructions. They say cut out two scale launch lugs and place on opposite sides of the rocket on the bottom between the fins and then it mentions a forward lug but gives no instruction on if it's another one of those or something else...

Is there a way to fix corrupted STL’s? Found the files to a WW2 looking bomb on Thingiverse to upscale to 4” but the tail cone file is corrupted and will not print right and I’m betting the other files are corrupted as well. https://www.thingiverse.com/thing:3920822

Lotus 3 minus decal. The decal was damaged upon arrival. 70 shipped

I could've sworn I saw 3D files for the Estes Blackbird nose and engine nozzles but I cannot seem to find it anywhere now. Has anyone printed those parts or know what website they'd be on?

Selling my Lotus 3 and Mach1 BT55 Blackbird kits. Thinning my pile and I don't have the time or space to mess with fiberglass kits anymore. I'll get pics later today. Lotus has been washed but not built and is $80 plus shipping, Blackbird is $50 plus shipping still in the bag.

Looking for a Madcow Cricket kit, seems like they decided to discontinue it at some point.

I ordered a Composite/Rocketry Warehouse full scale ARCAS on Black Friday that I’m still waiting on to ship but in the meantime, I’ve been looking at different techniques on building it and I noticed it has a molded-on tail cone so I can’t do my usual and take the aft ring off for fillets. I was...

Anyone have an OpenSCAD file for tail cones? Building a 38mm frame Black Brant III and noticed the Estes one has a tail cone on it.

I feel like a thread already exists but I can’t find it. I just purchased my first large fiberglass rocket (Rocketry Warehouse ARCAS) and I’m used to BSI epoxy but that would cost way too much for this. I’ve heard about US Composites and West Systems but have never used them and after looking...

What length/diameter ratio qualifies a rocket to be stubby.

Can a rocket have too much over-stability? Bought a Mach1 Alien Splitter last year, have yet to launch it because it flies too high around here on a G (1600ft) so I thought of trying an F67 as the rocket only weighs 1.6lbs or so loaded. Problem is, the design is at 9.1 stability which seems too...

Needing a chute for my 5.5 LOC Goblin and I noticed on Top Flight’s webpage, they claim a 50” chute will work for a 7-9lb rocket at 17-22ft/s. I’m assuming the 17ft/s is for the 7lb. Can anyone confirm these numbers? I’ve always been told a 6ft chute for 7-9lbs with a 17ft/s descent rate.

Bought this but don’t need it. Selling for what I bought it for. $50 shipped.
