The helicopter flying out of the tank of water was cool as hell.

You guys should make a submarine plane. It can fly like a normal one but then it can dive and function underwater. Not a bad challenge idea if you ask me.

I would rate this as the number one best RC tip I have seen. I live in rainy Oregon and often have tempted fate to try to get in some flying in between rain showers. So far I have not lost any electronics this way, but this idea will add a layer of insurance. Thank you!

I just want to say thanks for everything you guys are doing. Your videos are a big part of what inspired me to try flying multirotors. Now I have 2 450 size and 1 230 size quadcoptes. You walked me through my first FPV setup, and so much more. I'm about to build my first plane now, and your videos have taught me everything I need to know to do that too! Now this video showed me how I can fly my new plane in Oregons nasty rainy weather! Thanks again.

Such a great video. Josh asks all the right questions and Peter gives all the right answers. Great editing and sound too.

This is one of the most useful videos I've ever watched. Thank you man!!

Thank you Peter. I have been using Corrosion X red label for years, saved many rec, escs and servos. I learned about it on the WaterPlanes Forum on RC Groups. I also ordered it from the dist. in Michigan. Later I found small cans of it at my local hardware store. I also use it on light bulbs in the car, house, connections on my trailers and all those lights. It works great. I also use it on the tongue jacks on trailers, and I know some people who buy it by the 5 gal cans and use it on snowmobile trailers, their snowmobiles and all the other outdoor stuff they have that they want to keep lubricated and worry free.

I live near a lake, you have no idea how helpful this has been! Thank you!

Ive been viewing this channel for some time without subscribing and I have to say, you group of guys are awesome and informative and make youtube a much more better place in so many ways. Thanks guys for providing us with informative videos and taking the time to show us how to properly fix, build, and waterproof our drones.

even this is old video it is still insane, well done

Best RC hobby video in the world. Period.

Thanks FliteTest. Great timing for this, the wind picked up this morning and freed my Versa Wing from a very tall tree. It spent 3 rainy days up there. Although the wing and battery were a total loss I was able to save the electronics with a little spray. Looking forward to getting another one as I lost it on the second flight.

Good job Peter! Thanks for a very timely video just in time for snow season! Merry Xmas flite test team.

I like Peter's videos, he's always really informative. More Peter's tech tips!

This isn't natural feeling to watch!! But an interesting idea. I was so worried when Peter put the battery in before coating it. He brings an interesting new aspect to Flitetest. Nice work guys!!

thank you so much flight test for all the great advice and help to the community.

Man, I'm blown away by this stuff.... I need it bad!!! Thanks for the informative video guys!

Very nice guide! That underwater helicopter was amazing.

This was a great episode. Very useful info. We can sure use it up here in Minnesota. Thanks guys!

New guy to FPV, Hyperion 280 racer, been drinkin, I love you guys.

Everyone: Water and electricity dont mix FliteTest: *_Am i a joke to you?_*

This in my eyes is a Great Achievement and for you to bring it to us for free is nothing short of Awesome! Thank You so very much!

Thanks a lot for your great episodes, and this one in particular! Thanks to waterproofing my ESCs and motors I did NOT loose my entire tricopter mini prototype to water damage after crash landing it in a big puddle of water :-) Thanks again, keep up the good work :-)

It seems waterproofing electronics is easier than I thought. Thanks for sharing this great video!

Excellent stuff, that video is a must-watch. Thanks a bunch Josh, - and Peter.

Thanks for this video, it is going to save my solo drone, from splash downs during lake shoots. keep up the great work guys.

Wednesday should be renamed Peter's day :) Excellent job!

Make magazine did an article on this, and you guys were in it!! Very cool

Peter is the perfect kind of crazy for this show. Thanks gentlemen useful advise as usual.

Pending on price that is awesome!!! Little to no mess, and instant set up! No wait!

The best video! That guy is just full of info . Thank you

Thank you guys. you sacrificed your ESC and took the risk of sacrificing your other components and maybe your life too(putting a battery in water seems extremely dangerous) to help others understand how to waterproof electronics. This makes my respect for you guys even higher.🙏

I loved watching Josh's panicked expressions throughout.

~~~also loved when he went full geek on the servo exps and josh went DUH LOL. Love you guys happy holidays Flite Test and support :)))))))

i have a challenge for the Flite Test crew. make a fpv plane that can fly in the air and under the water :D bonus points if you can make that plane jump out of the water and take off to the sky. please up vote this, so they can see this post :3

Josh: Is this going to kill me? Peter: You'll be fine. Josh: Don't do this at home. Josh: Don't do this at home. Josh: I don't care if it works here. Don't do this at home.

You guys are awesome, just ordered all of it. Thank you!

I sail radio control schooners . this will be a great help , thank you for posting .

I used Corrosion X HD after watching this episode on a cheap HXT900 servo I have setup for my underwater ROV and so far it is waterproof in fresh water up to 40 feet deep so far. Next dive should be 80ft or more. Thanks Flite Test for the great idea!!!

I see much more potential for this stuff in other areas as well. Looks like good stuff !!! thanks for the info.

Guys! This is AMAZING. Thank you! Very awesome information. I run boats too, so guess what? I'm totally doing this!

I learnt the hard way when I used a non waterproof steering servo in my nitro RC car in the rain, one minute it's driving fine in a straight line then the servo starts twitching at full speed and flips the buggy. Make sure to water proof your servos or buy a water proof one! Great tips Flite test :)

Peter is awesome... You too Josh... and Josh... and Alex... and Chad... and David (miss that crazy Swede) and everybody at FliteTest...

FliteTest Thank you for posting this! This stuff isn't available in my country, and the description on amazon just says "anti corrosion lube". There is probably some analogue product available, but to find that you need to know what "Corrosion x" is. What is it? For a similar application I just put generic silicone grease in a syringe and fill up all the empty space, then I wrap it in vulcanizing tape. Is this similar to silicone grease? A thought on your heat shrink ESC solution, epoxy has the disadvantage that it is not pliable in its own. The manufacturer adds a softening agent (like BPA) so that it doesn't crack over time. This crates two problems: 1) The softening agent (regardless whether it is BPA or another softening agent) will migrate from the epoxy and into the other plastics that are in contact with the epoxy. When this migrates into the PCB board's coating, the wire coating and the heat shrink tube, this will alter the properties of these plastics. Migration is a big problem when you design things in plastic materials. 2) As the softening agents migrate out of the epoxy, the epoxy will lose its properties and no longer protect your ESC as you intended. You could avoid this by using vulcanizing silicone. Silicone does not need softening agents, and there are special types of vulcanizing silicone meant for electronics. They are usually sold as "heat sink adhesive" or "heat sink glue". They are thermally conductive, electrically insulating and doesn't damage the electronics. (Vulcanizing silicone will harden into a protective material, silicone paste, silicone grease or "thermal paste" will not harden.) You could easily take it one step further. If you use a syringe to inject the silicone into the heat shrink tube and replace the air, you get something called "pressure compensation". This means you can literally sink it to the bottom of the ocean and it wouldn't leak. You could solve your cooling problem by using thermally conductive silicone adhesive. You mention that by sealing the ESC in heat shrink tubing, you limit the cooling. But if you use vulcanizing silicone, the heat shrink tubing would only have the job to shape the silicone and protect it from abrasion or other mechanical damage. After you've shrunk the tubing you cut a hole right over the heat generating parts of the ESC. Now you add a very thin layer of the heat conductive vulcanizing silicone and add a metal heat sink. After this you fill the heat shrink tubing with silicone as before. This would create a perfectly waterproof ESC housing without sacrificing the cooling.

great vid josh and peter but is there one spray to use for all for just bad weather flying as opposed to full submersal?

you are a genius peter

Awesome video and very helpful info. I am curious as to the odd plane behind Peter at the end however. I don't recognize it at all.

For things with dip switches or tuning pots I have used silicone sealant. Means that it can be peeled off again easy. I have also heard of people using plasti dip as well. Can also use marine grease and pack their servos full of it, electronics and all to waterproof. I have also heard of grease used to protect connectors.

Most intriguing flite test episode ever

Just bookmarked this page, great info guys

You might consider sealing your heat shrink with RTV Silicone as well. Windshield sealant (RTV) will seep into crevices very well. If you think you might ever want to get back into your electronics, RTV would be a lot easier to dig out than epoxy!!! You might also want to try Dielectric grease. It's a little messy, but does a great job of keeping moisture out of connectors. I had a customer who wanted to waterproof his Satellite Broadcast Transmitter. TWTs (Traveling Wave Tubes) Normally run at about 8800vdc on the Cathode, 4400 and 2500 volts on the two collectors. He used Humiseal 1B31 to coat all the circuit boards and dielectric grease to seal all the connectors in his transmitter. Then he took it out to the parking lot...put it in transmit (that means with the High Voltage power supplies turned on) and put a garden hose in the chassis and turned it on!!! He ran it that way for half an hour with with the water running with no failures!!! I doubt you'll ever run into 8800 volt power supplies in your RC equipment, though! ;-)

Peter & Josh very good Video on water Proofing ! Thanks

Liquid electrical tape is also very useful, and it's pretty easy to remove. I did my video transmitter, FC, Radio, and ESCs and I was able to fly in pouring rain. I haven't tried it submerged, but it I'm sure it will work.

Finally, good content!!

Excellent work!

Wicked helpful information. Thank you.

This is awesome, I will be way more confident flying over the water with this. Good thing I can swim too!

thanks for a timely video, I recently crashed into a puddle and the esc stopped working. I was wondering if we could use the liquid electrical tape on the esc to water proof it ?

I've had good experiences coating my esc units in clear silicon caulking for waterproofing.

Great job guys!

Peter is the man

Awesome video, as usual I am late to the party. I found many uses for corrosion x the last 25 years on many corroded stuff and electronics. I would add is to be careful when using on your transmitter. The plastic on the screw areas and battery compartment in my tx JR 9x slowly fell apart. Remember to wipe away excess spray and keep it on the electronics only.

Very very Educational, Thank you. Hope you had a great Christmas guys.

thx for teaching me something new...this is great.

Thanks guys and its just started snowing UK

Can you do another one of these with some of the waterproofing stuff that's come out recently

When epoxying the esc, use the heat gun on the epoxy you put on to help it flow into all the gaps. You will get a better seal that way.

Standard 5 min epoxy is conductive to a point. I have been waterproofing electronics for over 15 years. For esc the best way is is by using 3m potting compound. You need to disassemble and then brush all 2 light coats over all the fets, resistors ect. Then put back together and you are good to go. Servos corrosion x is good. For the rx you need to remove from case take a small piece of styrofoam stick on pins temporarily and then spray with liquid electrical tape. I use clear but black will work. Spray a couple coats and you are golden with no loss of range. I have a entire thread on OSE offshore electrics forum from about 8 to 10 years ago showing the exact procedures. We were making our gas and nitro boats electronics waterproof long before there was fast electric boats and waterproof electronics for rc. Anyways awesome vid enjoyed watching.

Why don´t use Corrosion-X HD to all components? and thanks flitetest for a great episode!

Cool stuff.. ive been using rubber baloons to seal rx and esc's thx for sharing !

on a lot of the PCB's that Horizon sells, you'll see a clear nonglossy coating around some of the IC chips.

Amazing! Keep the good work!

this guy, Peter, is worth every penny he's paid....and I'm sure he's paid well -- this is awesome.

Excellent stuff. You guys are great

Great video, can't wait to try this stuff out!!! I want to CX my FPV gear, do you think it would it be ok to apply the CorrosionX to the antenna connector? Also, if I use the CorrosionX on a PDB, can I clean it off later if I need to re-solder a connection?

Have you tried sealing the ESC heat shrink wrap using Loctite 401? It adheres to silicone. It's great stuff.

Another great video .. the question I have is how long will it last on your electronics.. or do you have to use it every time you think your going to be around water ? This would be great on my float planes

That was super interesting. I wonder how it affects video signals underwater.

Take a look at Tough-Seal 21 to Pot your ESC's. I have used that product for potting instrumentation that we developed for NOAA. Works great in deep sea immersion and at low temps in Antarctica. It has also survived well in the Tropics of Sierra Leone

Peter thanks, All At flite test and every where Happy Christmas and new year.

hey for testing salinity content you can use electronic testors, or mechanical ones. salinity changes buoyancy. For Automotive battery, and radiators the mechanical testors use different pellets that float at different levels depending on electrolyte content. or a needle that floats.

+FliteTest why not use bathroom silicone for shielding the ESC ?

YOu are not "copying" them, you are crowd sourcing information; don't sell yourself short. You are obviously adding back to the community!

I wish I saw this video a long time ago! Great job!

@7:30 where your holding a DC Motor, can you spray Corrosion-X on the motor and inside it to protect against water? Thank you for the Great upload

So rad! Had no idea! I live on Maui and only place without vegetation is the beach. Long story short, brand new 1/8 scale, running full throttle, servo horn stripped. Straight into the ocean 🤑

Does caulk work to seal the ESC instead of the epoxy?

Thanks! I'm about to assemble a 2.1M Cessna 150 for use exclusivley on a salt water lagoon in Florida. This will help immensley.

I've loved this video for years and have used Corrosion X since then on all my RC stuff and many other uses. Now I've got an e-bike and am wondering if there's any reason(s) not to soak my mid-drive motor and electrics with Corrosion X. Any thoughts/advice would be greatly appreciated.

Excellent video! You guys should make a plane that flys under water. Subs can be complex with ballast tanks but wings can creat lift underwater (you just need waterproof foam!)

Great video, in most parts very informative! I would like to know what the stuff used on the motor was? "This stuff" &"WD40 on steroids"?

Great video. A question for the electronics gurus: What is the reason for CorrosionX and conformal coating not working on ESCs? (e.g. heat dissipation, current, high frequency AC?)

FYI, The Canadian alternative to CorrosionX is FluidFilm, available at most Canadian Tire stores. :)

is there a video on this channel to show how to build a plane and it goes into all the detail since i am very new

Peter ain't scared, fearless!

Plastidip works great! Been using it for 2 years in my RC cards... Works great!

for ur rotor bones kit, can u add all the hardware, like the props, esc, motors...

Great video but I also like the battery, ESC setup. It would be great for bench testing motors or ESC. How would you make something like that?

Superb video guys - thanks so much!

Good info! How long does it keep it waterproof for?
