One of the cautions against using canned air is that the powerful force might drive particles into crevices or vents and be difficult to remove if they cause a problem.Air puffer is less powerful and less likely to do that but it might.i use an air puffer to blow dust etc off the drone, or you can use canned air ,i make it part of my pre flight routine at home before i go out, at the same time you can check for damage, when you check the props you will often find insect splatter on them, just get a wet wipe or some damp kitchen roll and remove it and check for any damage, the same if there is splatter on the body of the drone
I suppose that could be a good idea if there was a protective coating of some sort that could be sprayed or applied to the drone, that would protect against any corrosion. I too leave my car close to the water and over time the build up of salt can be quite a lot so I can only imagine what it could potentially do to my drone over time.Never gave much thought to the seawater part. I live on Long Island & at the moment my car is parked 10' above sea level & just 50' away from in inlet. I remember a product we used for computers, an electronics wash, obviously not water based but basically spayed it on & blew it off with canned air.
From a photographers point of view the real damage from canned air is the liquid propellant that can escape and splatter sensors and other internal bits and bobs.One of the cautions against using canned air is that the powerful force might drive particles into crevices or vents and be difficult to remove if they cause a problem.Air puffer is less powerful and less likely to do that but it might.
The best use for canned air is to shake the can,turn it upside down and spray a fly in midair.Fly will freeze and fall and shatter on impactFrom a photographers point of view the real damage from canned air is the liquid propellant that can escape and splatter sensors and other internal bits and bobs.
Your post reminds me of my USAF days, where there was a similar rule on fresh water wash for aircraft flying below a certain altitude above ocean water - I think there was also an exposure duration there too...don't think a wash was required every time you flew an over water approach.I’ve wondered this since owning my MPP, i fly a lot over the sea and coast and I’ve always wondered if the salty sea air will have a negative effect on any of the motors or internals.
I work in aviation and when our aircraft fly below 500ft over seawater the engines require fresh water washes.
I know a drone is a lot different but I guess the principles are very similar but on a much smaller scale. Would salt crystals form in places I can’t see/reach over time?
Would my drone be getting salty air through any of the vents of in the motors? I try my best to clean the drone after each flight which is over the sea, but it’s always something that played in the back of my mind.
So it will always get dirty? Even with hand catching and launching?
Same in Arizona... one reason sunsets and “afterglow” is so beautiful here is the incredible amount of suspended particulate (dust) in the air... almost as bad is when all the citrus trees bloom and the pollen blows into the air... every thing literally turns yellow.The air is full of dust and bugs. Here in AUS anyway. Just and and do maintence and enjoy flying
