I want to connect a gps to my flight controller but cant seem to locate a open Ground pad, I have open rx,tx and voltage pad ,just dont have enough grounds 

Can i maby share a ground pad between 2 wires?

Yes, you can piggy back two wires onto a single pad.

yes you can, how i do this:

this naked wire next to 5v is a risk, i would suggest to improve that at the same time :-)

thanks for the help i will do that =)

FWIW, I have discovered (especially with small whoop boards)… if I need to “share a pad”.. I will make a “Y” cable” with wire, connect the components .. THEN, solder the single wire to the fc…
It minimizes the heat to the fc and less chance of a bridge.. plus, it’s easier when ur working in tight areas

Options. Pro and Con

1. stack two wires vertically.
- silicone gets in way.
- easy to get cold solder

2. Place wires side by side
- silicone gets in way
- need wide pad
- chance of short to adjacent

3. Place wires side by side - opposite directions
+ more compact
+ easier to check both are secure

4. Solder to different GND point like exposed wire
+ solder to vtx or rx gnd
+ or scratch off some silicone and solder somewhere midway
+ messy
