Is it better to cut them BEFORE or AFTER glassing the fuselage?

My experience has shown that fiberglass does not like to span even small holes elegantly, (voids/air pockets near the rim) however cutting thru cured epoxy/fiberglass is not kind to forstner bits.

Any thoughts?

I do all the fitting cutting and any pre-fabrication before I glass for paint,, just like I would before Iron on,,, I've found light cloth cuts away very easy out of open bays, I don't see a problem there at all,,

Only thing I suggest is you put some tape inside the tubes so you don't have to sand epoxy out later

good luck

Good Idea!

Thanks for the advice. I'l be using .5 oz cloth with thinned finishing epoxy and I probably would have realized I should've covered the ends of the tubes while I was trying to dig the resin out.
Would you also advise taping the servo and incidence adjuster holes from the inside of the fuselage?

No, you can trim the light cloth with a xacto knife later very easily,
