The motor mount is just a motor mount.

But, I tweaked the launch lugs a bit. The plans call for two risers, so the launch rod will clear the wider diameter of the nose cone. Atop those two risers would be placed two launch lugs.

I've found that 4th and 5th graders (or, as some may say aboot now, kids in grade 4 or grade 5), can have a tendency to break one lug when trying to lace the launch rod through two lugs. It's like they've never done this before and haven't yet developed the fine dexterity of lowering cardboard tubes onto long rigid wires.

So, I used some of my launch lug stock from BMS, IIRC, and put on one long launch lug straddling the two risers. Just get it started, and the launch rod can't miss.
