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

Hi, Mike,
Not sure exactly where, but I would definitely move them forward. My first instinct is to position them about midway along the length of the outer booster tube. If you add a coupler, then move the fins about another 1/4" forward.
