Why make a Patriot Pro clone?

I'm starting to rethink one of my 2023 rocketry projects.  Years ago I bought a 3" body tube and nose cone from North Coast Rocketry (when it was a part of Estes, ~1998) with the idea of building a Patriot Pro clone using a 4 X D12 engine cluster.  However, after reading a history of the Estes Pro Series on Ye Olde Rocket Forum I realized this was silly.  The excess weight of the four engines would make this a marginally stable rocket which would be unlikely to go very high, even on 4 E12 engines.  Four D engines = 1 F engine; four E engines = 1 G engine, but four E engines have a high likelihood of at least one of them experiencing catastrophic failure (CATO) and I can buy anything up to a G engine without Level 1 certification from Apogee and other vendors.  A better use for this body tube and nose cone would be to build a clone of an Estes Leviathan, with a 29 mm engine mount capable of taking Estes E & F engines and larger AeroTech engines (up to G).  A company called Launch Lab Rocketry sells a conversion kit to make a Leviathan out of an Estes Big Daddy kit, but why spend $30 or more for a rocket just to use the body tube and nose cone when I've already got what I need to build a 43" tall Leviathan?  I'll just buy some laser cut plywood centering rings for a 29 mm engine mount along with four plywood fins, use the 24" nylon parachute I just bought from Estes and I've got a new rocket.  The plans for the Patriot Pro look cool, but I've been stalled trying to hand cut the centering rings to accommodate four 24 mm engine tubes.

The Leviathan was 41.5" tall with a 3" diameter, and sold from 2012-2015 as a Pro Series II rocket, with a projected altitude of 1500 ft on a G80-7T engine (a discontinued Estes engine).

My version will be a couple of inches longer (43"), but should be a great rocket for larger fields and larger engines.  I'll order the fins and centering rings from EBay and should be able to complete this rocket in the spring.  I'm not sure whether I'll match the original color scheme or not but I definitely a) need to make it visible and b) need to use the JLCR to control rocket recovery.

3D printing a rocket no longer produced using OpenRocket

Image
Well, I finally decided to try merging my software skills with my new toy to try to recreate an out-of-production rocket, the 37 inch tall Estes Maxi Brute Honest John  (available 1975-1983; on page 31 of the Estes catalog at  https://cdn.shopify.com/s/files/1/0686/0220/0369/files/Estes_1975_Catalog.pdf ).  The nose cone is unique and no longer available, so I decided to try to take advantage of a new feature in OpenRocket version 23.09 that allows the export of parts of a rocket as an .OBJ file, suitable for 3D printing.  The OpenRocket team put together a great tutorial describing the process.   Luckily for me, someone posted a RockSim file for the Maxi Brute Honest John on RocketReviews.com in 2010, and OpenRocket supports the import of RockSim .rkt files so I thought I'd give it a try. OpenRocket displays the nose cone in two parts, a cone and a "transition" that inserts into the body tube.  Selecting each part in the OpenRocket design then choosing File/ExportAs al

Resurrecting my X-15 with my scratch STRETCH X-15

Image
Back when I used to launch rockets with my kids, I built a model from scratch of an Estes X-15 (here's my old fleet ).  It flew great the first time , but on the second flight , the shock cord must have burned through because all I ever recovered was the nose cone and parachute.  I always like the looks of that rocket, partly because of its role in getting astronauts ready for spaceflight, and kept going back to look at the plans on Jim Z‘s site .  I finally decided to build a new one, starting from the nose cone I recovered.  I printed the plans , cut fins from 3/8" balsa wood (more on that in a moment), cut the body tube (BT-60, 1.637" diameter), glued the fins together on wax paper, brushed them with wood filler and sanded them to get ready for assembly. I decided to use some epoxy putty to make a "cockpit" on the nose cone and plan to use Kevlar to avoid having the next shock cord burn through. After gluing the fins together on wax paper, I coated them with

Building my SpaceX BFR

Image
 I've always admired the retro look of the SpaceX rockets but didn't want to pay $150 for the ready-to-fly SpaceX Falcon 9 model from Estes.  When browsing Thingiverse I came across a f lying version of the Starship Super-Heavy by jsheedy , previously known as the SpaceX "BFR" (let's go with " Big Flying Rocket ").   The author provided files to 3D print the "BFR" nose cone, transition and fins designed to take my favorite 2.6" diameter body tube (BT-80).  I used some modifications made by jgutz20 on Thingiverse , allowing just the Starship to be a rocket by itself without needing a booster stage.   Starship BT-80 Full by jgutz20 on Thingiverse , not mine! I printed jgutz20's nose cone, which includes modifications attach a parachute and shock cord and 3D printed launch lugs, along with other parts from jsheedy (below), then built an OpenRocket simulation file based on their weights and fin shape to ensure its stability and pred
