Protection from water
Various methods are available, but not all are applicable to all parts of an RC aircraft:
- Hot glue
- Liquid electrical tape
- Conformal coating
- Heatshrink tubing
Methods 7+3 or 7+2 can be used together. The glue is used to shield the ends of the tubing.
No protection is generally needed. Just make sure the solder joints are covered.
Protecting PCBs (e.g. Flight Controllers, Receivers etc)
Methods 2, 4, 5, 6 are known to work, but all have cons and pros:
- 2: heavy, can't be easily removed
- 4: a bit heavy, can't be easily removed
- 5: should be the best, as it can be soldered through
- 6: messy
Board cameras can be coated with 4, and probably other methods. Mobius etc cameras need to have all holes/buttons covered. More experience is needed.
Protecting other electronics
Methods 4, 5 ,6 probably.
Use 8: tupperware or other plastic food boxes. make holes for cables coming in/out but insulate them. Motors need to be left outside the box obviously. Be weary of heat issues in the box!
Protection from the sun
On a sunny day, in a sunny country, electronics may be heated overly by sun, especially while the vehicle is stationary (no airflow, e.g. when waiting for GPS satellite acquisition). Copper or aluminum tape can be used to protect these components and help reflect sunlight.
