The same goes for surface mounted fins. But you apply fillets and it's good.
Like Galadriel in the Rings of Power: "You have not seen what I have seen." Younglings and Collegiate Aerospace Students seduced by the dark side power of motorized pods. Brutally rejected at the RSO table by qualified Level Two and Three Jedi Masters, they are sent to "That guy over there in the corner of the parking lot, he will help you."
As a very forgiving oddroc scum I have received many power podded abominations on my tail gate. From motors directly super glued (or even hot glued) to paper towel tubes, to fully simmed college projects severely lacking in build quality and utilizing poorly connected Estes starters for elaborate clustered boosters.
The horror. Pods ripped off, tubes scored and reglued. Field tabs or straps added. Launch lug reinforced fillets added, some with dowels stuck into them to make amusing Pew-Pew laser cannon add-ons. Anything to further bonding over larger surface areas. Thick super glue with quick-set spray; not a pleasant, time consuming, good technique, double bond wood glue process.
Younglings and Padawans, feel the force flow between the motor, the pod or fall away booster attachment, the rocket's thrust centerline, the nose weight. Learn the ways of the Jedi and open your eyes to a much broader world. If you are not grievously injured by your flight, we will watch your rocket building career with much interest.
So looking forward to these power pods being loaded for Bear. Plugged red lables matched to awesome 29mm core power. Four big flames going fantasy supersonic.
