RC CG Point

prusaprinters

These pointed dots are quite small. ( 5mm across )   I print them in white and paint as needed and glue them in the exact spot where the CG is located.  They are easily located with your finger because of the small point I put on them.   No more trying to see underneath at the same time fighting to balance the plane. I print 32 at a time at 100% infill with a brim so they don't get misplaced and stay put until I need them. It takes about 12 minutes without a brim or 17 with a brim to get the job done and it saves a lot of frustration.   Generic PLA works for me.
