Finishing up:
I attached the rotors, and added a bit of CA coating a few places that are likely to get handled a lot. And, as promised, fixed up the Sharpie at the front:
Everything fits together nicely. Final weight is about 2.5g heavier than the facecard value, which makes sense for the stuff I added. If I were doing this again, I would have needed to add less stuff (like that ridiculous cardstock wrap at the front).
On minor annoyance that I discovered:
My hold-down clips cover part of the tail where tape is applied to hold in the motor. Only 1/4" is left exposed (now coated with CA, natch). I don't have any concern about it having enough contact area to hold, but I'll have to cut the tape narrow to fit it in there. Another fix to be made in a 2.0 version, should there ever be one.
