Had another negative encounter, it's been a few years since the last one, just an uneducated ******, going on about drones being illegal yada yada yada.    :-/
Still that didn't spoil my flying time, had an absolute blast  ~~

DB that just means you have shed loads of props in the first place ;-)

Just had a thought, even with all the crashing I've done, I haven't bought any replacement props in over a year ~~

May the sun shine and winds be light for BFU#8. Son't forget lots of vids for those of us unable to attend.  :D

While sitting here watching the rain come down in Yorkshire stair rods a thought trickled its way into the conscious side of my brain. The average multi has a number of sensors or small circuit boards in various exposed areas of the craft. What would be the negative impact of spraying with a silicon spray (obviously avoiding sensors) to make them water proof or at least water resistant? Silicon has a high dielectric strength so shouldn';t cause a problem?  :hmm:

Also I thought about a basic waterproofing of an IMU with carefully applied heatshrink. Would it interfere with its operation? Anyone tried either method? :hmm:

Just thinking about adding a bit more resistance to light rain, not downpours or river dunking!  :whistling:

We use Silicon spray on our two-way radios I do repairs for the RNLI and lifeguards etc I always cover their radios to Silicon spray you';d be amazed at how well it helps the thing to remember is it is a good insulator so just be careful you don';t get too much on the contacts cover them up first

Put it all in a waterproof box?

Would need to be a big box!! :o

Very simple cheap way is to put a latex glove over electrics and cable tie round wires

Just spray it with this stuff when it';s available :smiley:


I don';t see why it wouldn';t take off from under water as long as you had a radio signal.

Looks impressive!  ~~

Wonder when it will become commercially available here?

How well do you think it would work on things like a Naza, ESC';s or the Rx where you cannot easily get inside?

Who would be prepared to try it in a pond?  :hmm:

Yeah I saw that video too, it';s a bit naff but I';m sure it won';t be long until someone perfects it.

The Rustoleum looks like something with a very interesting future.
There will be some situations where being able to ensure that water does not penetrate for a short time will already be a big deal.  It is a product to follow.

It';s not new, it';s been about for quite a while now if they are using the same technology - used it to make windscreens on rally cars keep clear, almost made wipers unnecessary.

Its so expensive  :cry, I wonder too if you coated the entire board would the Rx plugs ETC still make good contact it would be a very expensive experiment if it went wrong. I just fly on dry days and away from water whenever possible  :crossfingers:

Would be best to mask any connectors, barometers etc before using it

The future of waterproofing technology is a nano-tech coating along the lines of what';s been posted already. The difference is how it';s applied.

If you put your electronics in a vacuum chamber then inject enough molecules of the coating in gas form, the molecules perfectly evenly coat the outside of whatever you put in the chamber - where ';outside'; includes the insides and any air / water gaps that might exist.

Water will run straight off the circuit boards.

At the moment they are deperately trying to get the economies of scale up so that they can install a few of these machines in a large mobile phone factory. So many phones get damages / returned due to water damage that the first person to get this working on a mass scale, cheaply enough, will make a lot of money.

The spray on coatings work similarly well but wear off far too quickly to be useful. If you coat the inside of all your electronics in a vacuum chamber it lasts much better.

It doesn';t help us much right now but i may try and borrow some time on my dads waterproofing machine at some point in the future, if possible.
