FPV Worry Free is Better Than KOTKING. FPV Drone waterproof coating – kotking vs worry free – Review
And so yeah i mean good job man, good job im, really pleased with that. I was going into this kind of expecting. This was just gon na, be like another knock off like you know, not really any better than coat king or any different, but this is definitely different from coat king and i definitely recommend this fpv worry free over codeking. Also, i mean good move with the branding, because fpv pilots are probably going to want to buy something. Thats called fpv worry free and has you know brandon, fpv name and branding on it, as opposed to codeking, which is rc coding and theres, not a whole lot of like familiar branding with this and its like? Who are they where they come from? You know you dont know, whereas this you got the face of brandon fpv whos, a professional fpv pilot and youre like oh okay, yeah, so yeah good move there, man all right. I need to go, buy another tube of this and coat everything. So all right. Sweet! Welcome back to rc with adam, and that is the bottom line on fpv worry free, hope you enjoyed that were going to talk about some important details and disclaimers in just a second. But first i want to say thanks to our sponsor for today, pcb way pcb way makes custom printed circuit boards. So if you have some kind of cool diy project – and you can draw up a circuit board schematic – you can send that over to them, theyll make it for you.
They got all kinds of options and they can actually put it all together with your custom. Electronic selection uh on the board and put it all together, its just amazing, its amazing. You just got ta, go check them out. Also they do rapid, prototyping and theyve done some of that for me and its turned out quite nicely, so they do 3d printing. They do injection molding sheet metal, cnc, machining, all kinds of different stuff, so if youre working on a diy project definitely go check out pcb way, link in the description now lets get on with this video now. First thing i want to get out of the way right away is uh. Brandon fpv did send this to me for like a dollar to test out, so technically i paid for it, but technically it was also heavily discounted, but either way you know thats not enough to make me say that somethings good just because they send it to me. This, in fact, is much better than coat king and were going to see why, in this whole, video its going to be kind of a long one, but i want to give you all the details just in case you are interested in it. The second disclaimer is that this is just a workbench kind of laboratory, laboratory sort of setup, and i havent actually tested this out on a quad in the field. Yet my main concern about that would be potential overheating issues that you might have by applying such a thick coating of waterproofing material, but other people have flown this a lot and i havent heard of any issues about overheating and its winter time right now.
So its going to be a while till i can test this out in the summer and you can see in the side by side the coat king is very yellow compared to the fpv worry free and the fpv worry free seems to drip a little bit more. Its been maybe about two hours, the fpv worry free is like its not even really tacky but its like grippy, whereas the code king is like you see, it grabs my finger like that. The worry free feels way more solid, far more pleasant texture. It doesnt feel like its going to stick to a bunch of stuff which that could be actually a really really big deal, so it has been not quite 24 hours now. These things are like fully cured. Fpv worry free. It basically feels like a silicone caulking, its grippy, but it its not sticky. The code. King is definitely sticky. Its actually sticky, like it doesnt, leave a residue, but it it kind of grips my finger and its its definitely softer all right now, its time to actually get some escs and put the fpv worry free on these guys im using two different escs for this test. Im going to use a small one like for a quadcopter and then this larger one like for an airplane. Now this has a heatsink on it. As you can see, i just took it off right there, but what i want to do is actually leave the heatsink on and ill be waterproofing kind of around those fets and well see that in just a second.
But first weve got to put some alcohol on this and do a little scrub. A dub to you, know clean it up and get everything so itll stick the best and here im going to take apart the small esc and do the same thing with the alcohol. Here we go lets just start applying this stuff. Now ive learned from previous from the previous tests with codeking that really you need to apply a lot. You really dont want to wimp out so just put a bunch on there, because it will kind of ooze down and it wont be as tall as you would think, see that right there in the middle, see how theres like a tiny little spot, where it hasnt. Quite gotten to it, if i just kind of im, just going to add a little bit more right there and its pretty thick right now, but it will ooze down. Actually, it looks like theres a bubble, so im gon na kind of move that around a little bit so its been about an hour lets see how goopy this is so its still kind of squishy. It did not drip as much as i had thought right here. Its actually not covered, i dont know if thats going to be a problem or not, but thatll probably drip over from the other side very tacky. But it doesnt seem like its going to ooze anymore im going to apply a layer between the escs or between the fats.
If i cant so im going to try and get this basically across all of the metal contacts. But i dont want to get it on the top of the fets. Now that i have that first coat on there, while its still wet ill. Take this heatsink and place it on here yeah. You can see theres still a gap there, but ive kind of this little uh point right in there and that keeps this from getting clogged up. Wow right here right there move along here all right. So it looks like its all right so heres. What we have this one might fail, because it does seem like its hard to tell whether these high spots on here are totally covered, but were just gon na go for it and see what one coat gives us. I think this is one coat. I want to say its one coat on each side well see if this works, if not thats kind of understandable, but i just want to see if itll work with one coat right here this one i am leaving this heat sink on so ive kind of used. The the worry free, the silicone stuff as a way of gluing on this heat sink and, as i showed earlier, i did waterproof like this board should be waterproof anyway, but then i sealed around the heatsink, so it should be extra waterproof. This guy were going to be using this to control. The escs right here will be our test: motor in 2205, 2300 kv and ovonic 4s 1500 milliamp hour battery.
Okay, very very salty, like super duper, salty, crazy, salty, okay, so for this test i will be using this. The v fly shortsaber 2. What this will do is if the salt water does cause a bad connection on the esc, which would cause it to draw more amps than it should then. This short saver is going to shut off the electricity to the motors. Otherwise, if i didnt have this, the motor might just go crazy and potentially melt down. Okay, everythings working uh there we go our motor is turning on okay, so lets start out first with the motor not running im just gon na dunk this in here. Okay, oh wow, all right so far, so good, oh yeah, its working, its working baby, wow thats, actually thats, very, very effective, okay, so success on the first try we before we conclude lets turn on our motors just a little bit and then lets give this a Little shaky shake in here: okay, all right, wow, all right, im, not exactly sure how its better than coke king like what what brandon did to make this a better formula, but it seems to be a better formula with a liv with with a single liberal coating Applied it somehow just sticks better and its less likely to drip off tall circuit board areas, so thats thats, really good. This is really good. All right, just yeah, okay, i think im a fan now good job brandon way to go man way to make something for the fpv community and uh, and you know, improve something and put it out there and make it.
You know better yeah baby, oh so this esc, just passed with flying colors, were going to test out this little guy right here, hes like that anyway, that doesnt really matter, but so the motor works. We know it works, lets go ahead and dunk this little guy. In here, uh, okay lets dunk it the other way holy crap wowzers, all right wow. I i really was pretty sure that wasnt gon na work on the first try all right. So the last test is to see how easy it is to remove this uh. Fpv worry free for soldering or how easy is it to swap wires after weve? You know applied the coating because lets say these are motor wires and we want to swap them out or switch a motor or something like that. Ts 100 soldering iron were going to start out at 310 degrees celsius, thats thats a kind of a mess if we can kind of stab through this coating here. Uh, okay lets try something else here, its very its very slippery, because its basically just some type of silicone okay. Now this part, this part is just. I think this is just always going to be a mess, its tricky, because you cant really pull it out of the way because it just springs back into place. Maybe we can just sort of like rub it off yeah. We can kind of do that and well. Well, obviously, need to re coat.
This lets take it up to to earth 330. There we go now. I have to be careful because, okay, because i dont want this to like fling out of the way yeah. So you can see we have some. We have some of the coating kind of holding the wire in place, so thats also kind of a bonus because then, even if you dont have a great solder joint, the coating will kind of hold everything together and youre less likely to have a wire come out. Let me get a razor knife and just kind of now this could be really tricky depending on you know the pad that youre cutting like if this was on a flight controller. You definitely want to be very careful to not scratch the flight controller pads there. We go get some good solder contact and pull it out there. We go okay, so well just try and get as much of this silicone off of here. Okay, well get our soldering iron. Well, add a bunch of solder to the iron and then lets say we want to put this back on here, so well heat this one up heat those up, im kind of pressing it in there back onto the pad. Okay, i think theyre together and there we go. I guess thats about, as you know, about as straightforward as it gets putting them back on there. So thats, not too bad its just. It is annoying. I mean its its just not as easy as working with uncoated uh wires.
I think thats just kind of a thats just kind of a given i mean the only thing thatd be easier, would be conformal coding, but as weve seen with the previous tests, conformal coding just does not perform the same as this stuff does and it doesnt seem To perform very well against salt, water and and against physical abrasion, and that kind of thing yeah, thats, really ugly uh. But the main thing is, you want to make sure your soldering iron is nice and hot, so 330 degrees celsius or maybe even hotter, and then obviously dont burn the pads. But then you really want to press it back into place to make sure you get past. Any silicone coating im assuming this is silicone. It seems to be like silicone ive gotten past, that test so thats. What you need to do, and then you just put some more on top of there and on both sides, make sure it gets all over the place and then youre good to go hey heres, another fun fact that might be relevant in some cases. I left this esc on here with the worry free coating on there and it was clamped in this little little gripper arm here and when i took it out, it was smooshed and deformed, and i dont know if that really matters i mean it does matter. Obviously, because it could mess with your waterproofing coating on here, but uh. Just keep that in mind.
In case you have a zip tie holding something down that has the waterproof coating on it, then its probably going to start to dig into the coating and and kind of deform it and that could affect the waterproofing capability. So keep that in mind.
