I have redesigned my older Alien atmospheric probe rocket. The previous version had stability issues - the main fins needed to be wider, and the strakes seemed to introduce even more instability (particularly since they were so long it was really difficult to get the glued on straight).
I redesigned the rocket, keeping the older nosecone assembly, but upping the main body tube from a BT-55 to a BT-60. I cut down an BT-60 nosecone to make a transition to insert the old BT-55 nosecone into. I also used an BT-60 plastic tailcone. I also upped the rear fins width and went from 3 fins to 4, and added an integral semi-strake attached to the main fin.
Old rocket:
New rocket:
I will take a few pictures of the build process, but all in all it is pretty straightforward.
