How to Solder Battery Lead to RX42-D Micro receiver

Im not the greatest solderer so if i can pull this off, you can too.
few tips for successful soldering:
1. make sure your solder tip is nice and clean ( i like using wet tissue, clean tip after every solder )
2. make sure your soldering iron is VERY hot before you start soldering. ( 450°F to 650°F is ideal ) Here i am using 450°F generic iron.
3. do not hold iron too long on surface, a quick tap will suffice.
4. use small amount of flux if your iron does not have flux core ( here i only used flux on wire end, the receiver is very small so i did not want to over heat the board, no flux needed there.
5. use a magnifying glass if your eyes can not see very well.
6. heat the wire (tin) for few seconds first before applying solder ( i did not heat the wire in this video, oops )
7. take your time, soldering is actually pretty fun once you get the hang of it.
8. practice on a piece of metal, practice makes perfect.
