Here's a tip I wanted to share. Maybe some of the old modellers know this anyway! But may be useful to some. My cheap RC Lidl twin fusi will be maidened soon.

Oooh feelable lumpies where cg should be. I like it. Teensy screws should work also.

I always use a dowel to punch an indent into the right spot. Raised bumps are probably more accurate with big fingers like mine.

I've seen some good ideas come up since posting this. Somebody suggested model making pins are even better, of even a blob of hot glue!
