I moved not all that long ago. So, my rockets are buried in boxes in the attic where I can't get to them. Worse, I didn't have a way of getting photographs of my Magnum mods back in the day. So, I'll try to describe them for you.
In 1990, I returned to the US after my stint in the USAF, and while I was waiting for my acceptance into college, I rediscovered my love of model rocketry. One of my pride and joy's was the Magnum. However, I didn't like the gap between the lower edge of the upper stage's fins and the upper edge of the booster. I bought some balsa (1/8" if I remember correctly) and created my own fin that kept the original upper stage's angle, filled in the gap, and continued the line of the booster's outside edge on the upper's outside edge.
I also have a habit of chopping off the tops of the payload section's coupler and the bottom off of the nosecone (this greatly increases the payload section's available area, but the nosecone is now for payload duty only). I'd paint the inside of the coupler and the nosecone the body colour and I feel this greatly improved the look of the rocket upon close examination.
You'll have to take my word for it, the paint and decals were some of my finest work. I launched it several times at the local school's playground, until the upper stage failed to ignite, and the rocket ballistically came down in the school's neighbor's produce garden (about 4 inches stuck into the dirt). Save for the booster section (and the upper stage's unlit C6-7 engine), the remains were not salvageable.
A 2nd attempt was made, and it Catoed on it's first launch. The booster engine exploded and in the process knocked the upper stage's mount loose, and ignited the C6-7. The rocket flew off with the nose pointed straight up, but at an angle reminiscent of a Naval surface launched cruise missile, then fell to the ground and ejected the parachute after impacting. My roommate's 8-year-old nearly reached the rocket before a yell stopped him short of grabbing the rocket before the ejection charge fired.
After that, I stopped painting my rockets until after I launched and recovered them at least once.
I built a second variation of the rocket from the salvaged payload section of the catoed rocket, and a purposely bought and cannibalized Mean Machine (this one lacked the Magnum's decals for obvious reasons). This time, I kept the lines of the upper stage's fins (and increased the count to 4), and designed a slightly larger version of the upper stage's fins for the booster. This rocket flew beautifully and in a stroke of luck on one of its flights, the booster engine ejected itself from the booster stage, this allowed the stage to glide down like a boost glider. On one of my most memorable launches, I launched it (single stage) on a windy day. The rocket got up about 45' before a sudden gust canted the rocket into a nearly horizontal trajectory, directly over the heads of a soccer match, and heading straight for the soccer match's fans sitting on their 2nd floor deck at a nearby apartment complex. I honestly thought that the rocket would impact directly in and amongst the fans. Fortunately, less than a hundred feet from them, the ejection charge finally deployed the chute, and due to the wind, the rocket sailed back over the heads of the now paused soccer match and into my hands less than 18 feet from it's launching point. Oh how I wish I had a video camera back in the 90's.
I have a desire of building this again someday, and perhaps with a keychain video camera (or 2 or 3) payload. I'd love to get a look back, look ahead, and side view of a rocket launch, but only if I'm certain I'll recover the thing.
