	Now you want to apply solder paste to your PCB, BUT, before you apply solder paste to your PCB's with a stencil, make sure to wipe down both the PCB and the stencil with isopropanol alcohol to clean the surface, this helps more than you would think. Once the IPA has evaporated, align your stencil on top of the PCB, and use masking tape or painters tape on one side to act as a hinge, so after you apply the solder paste, you can carefully remove the stencil. Please reference Clemen's Youtube video for soldering: https://youtu.be/Y16kbAK3vaU		Now you want to apply solder paste to your PCB, BUT, before you apply solder paste to your PCB's with a stencil, make sure to wipe down both the PCB and the stencil with isopropanol alcohol to clean the surface, this helps more than you would think.

-Get Organized: Before you start assembling and soldering the PCB's, it's recommended to organize all of your parts. One method is to print off the iBOM.html file, tape it to a piece of cardboard, and then put double sided tape next to each line item. Only take out the parts/components you need for (1) xESC at a time, or the parts for the Mainboard, then place them on the double sided tape. Here are a couple of examples:
