You will have better flights on a full 40 n-sec E15/18 or E28/30 Aerotech Composite.
All the 24 and 29mm BP SU engines from Estes are what I would call "barely adequate" for anything classified as a "Maxi Brute"; case in point, the 1/45 Little Joe II has ONLY the E30 as a suggested motor; ZERO BP motors.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !
