This is not a beginner project; you need the necessary equipment and practice to successfully assemble this board. I used BGA packages and 0402 size passive components in the design to minimise the size and weight of the board which is crucial for an RC receiver. If you have never dealt with those type of hardware assembly better not to start here. The minimum essential tools you need:

• Hot air gun (or reflow oven even better)
• Stereo microscope or at least a 4x magnifying glass lamp
• Quality tweezers (forget those AliBanggoodExpress stuff)
• Good quality solder paste
• Quality flux
• Stencil at least for the BGA
• And lot of practice
