Is it possible to waterproof or at least make the phantom 2 mildly resistant to rain??
well you could cover the vents, but that would cause the internals to over heat. I think you can buy waterproof shells but they still cause over heating
if your flying in really cold conditions then you can partially cover up the vents
Lots of good information here.
You could do that, but water would still get in the shell and just sit there causing dry rot
It would be possible to seal up the shell. The two critical issues are cooling the ESCS and venting the barometer to atmosphere. Both are easily solved.
what if we did not fully cover them, but just put like a tiny cover over, not the whole way over through ?
Even if waterproof, just a few raindrops on the lens will ruin any chance of getting good images.
You really need to cover more than the vents. The shell of the Phantom is open around the motors. Water could be easily blown down into the shell and short out the ESC's if they were not coated to be waterproof. The ends of the arms could be plugged with something like silicone putty to prevent water from getting in from the motor openings. ESC's can be cooled with heat sinks and do not really need outside air. I have built several quads that are waterproof and floating, using the Dex shells. I have had flight times up to 47 minutes without overheating the electronics.On a completely sealed, watertight shell, the barometer in the flight controller must be vented to atmosphere. You can use a Gortex or neoprene patch or a flexible diaphragm. If the compass is mounted separately on the landing gear, it will need to be waterproofed. A bit of dielectric grease will keep water out of the connector. If the compass is mounted in an external plastic housing with the GPS module, then it is a simple matter to seal up the plastic housing.
With the Phantom, I would be more worried about the camera and gimbal getting wet. These might tolerate a light rain as they are under the umbrella of the Phantom body. They would be difficult to seal watertight but not impossible.
