This is a rocket that looks like it should be a two stage attempt. So I did. Went with 3 fins and going with C size motors. I have another one of these kits that I will build to the plans.
Interesting mod! I can see why it looks like it should be a two stage. Conversely, I thought it was a design homage to the RIM-8 Talos missile, minus the booster.
Looks great!!! I'm sure it will fly very well in 2-stage configuration. I believe you've inspired me to go pick one of these kits up at Hobby Lobby. I envision adding a payload section to the top to loft videocams, altimeters, etc.
Flew my version this weekend at Michiana Mayhem. Great flight on D12-0 staged to C6-5. Watched the sustainer drift away over the down range farm - oh well, will have to build another! (And use a streamer next time!)
Ok I picked up two Esam-58. I did this one as per instruction except with a D size instead of a C. The next one will be two stage. Debating on D too C or with my original thought of two D's
I only added the clay weight that came with the kit (14g, I think?) for my two-stage Red Nova conversion. I did move the upper fins rearward 1" from the original design, and that is where the stage separation point is. My OR sim file is posted previously.
