Motor has a little rattle in motor mount

[Paul Farmer]

I'm building a fiberglass Mad Dog 6 and when I dry fitted the Aero pack 98 to 75mm adaptor in the 98mm motor tube there seems to be a little rattle. More than Im comfortable with. Maybe a 1/16 play. Is this the norm. This is my first fiberglass rocket build and I have never experienced this kind of play even with a motor adaptor. Any advice?

Not a big deal. The slimline retainers I use give more slop than that and fly fine.
