About 2 years ago I built an Estes Plasma Probe for the heck of it because while I love to fly big rockets...I also love to fly little ones. And this one is just gorgeous. It flies exceptionally well on B6-4's and C6-5's. From the time I built it I had always wanted to upscale it. So when I bought the materials for my "Der Mad Max" I also added a section of 3" BlueTube for this design and had Upscale CNC cut both fin-ring sets at the same time to save on materials costs.
The original kit was 18.25" long and flew on 18mm motors. Forward section was BT20, Aft section was BT 50. Scaling it up to 3.01x almost perfectly scales the rocket to 4" and 3" airframe along with a 54mm motor tube. The motor tube diameter is critical because the aft section is exposed in the design. The upscale length
I have a 4:1 PML nosecone that scales perfectly. The only thing that does not scale properly is the 3"-4" transition available through LOC precision. The transition is about 1.5" too short in length. I suppose I could have one 3D printed, or I can fabricate it using the BlueTube. Haven't decided yet. I will either reach out to Stickershock for the vinyl decals or I will print my own waterslides.
Unlike Der Mad Max, this will be a slow sub-mach rocket that I will fly with longer burn motors and skidmarks. I want this to give a nice show. Here are images of the design.
