Slight upscale of the Odd'l Rockets BT-5 based Corkscrew kit.
3" diameter offset ring stability. Streamer recovery.
It hasn't been painted, this is a stability test model. Heavy walled BT-20 and a BT-70 sized offset ring provides stability. The original Odd'l kit was a BT-5 based model. It did some wiggling on the way up as planned.
