Would it be better to mount the fins so that the leading edge of the fin is even with the front of the booster's body tube? Also, both engines remained in the 2 stages. Best regards, Mike

You could also try locating the booster fins using this old school method from the Estes TR-2 white paper. I'll bet it comes pretty close to Doug's "that looks about right" placement.
