I've been busy busy designing rockets to build this year. Next up is a futuristic missile, inspired by the Estes QCC Explorer.
This should be 40" long, BT-80 sized tube, hoping to use some LOC 2.56 tubing if I can find any. I intend to use 1/8" plywood rear fins, and the rest of the "fins/strakes" are balsa (1"x1/2", 5/16" x 1/2", and 1/8"). Should fly on Aerotech F composites, with low-G a possibility (I'm not certified level 1 so my G choices are limited).
I had a devil of a time tweaking the design; it was overstable initially, and it was challenging trying to get the engine's ejection delay to more closely match the "optimum delay" in Rocksim. Just about there, but as I don't have it built yet, nor the plywood on hand I can't weigh certain items to get an accurate weight. Same with glue/paint weight, though I've assigned that as 15% of the unbuilt weight in keeping with my previous builds.
I will have to cut off an BT-80 nosecone to get the rear transition - I had originally not wanted one, but it was the only way I could figure out to lower the stability below 2 for most motors.
Rocksim file attached, in case anyone wants to look at it, or offer suggestions.
