@@EastTactics okay, I saw that before but I’m in doubt because ultimately, the will have to go to the balancer of a 3S battery. Are the outer edges of a balancer cable positive and negative even though the colors aren’t necessarily red and black? In other words, what if I were to pick up the battery in my hand and remove the two center leads off it’s Balance or Cables. Would ice still get the proper positive and negative power from the two outer edge wires?
You definitely don’t want to mess with the wires on the battery itself. Just the terminals on the connector. To answer your question regarding batteries, the answer is yes, the outside ones will always be a positive and a negative but they should also be marked accordingly by the color. The batteries should all be exactly the same. And by default they really should be a red and black on the outside automatically on every battery you ever see. If that’s not the case then that’s a little bit odd. but either way it’s just an outer covering If after hooking up your fan (or splitter) with the balance terminal connector, and you find it’s not working, then try switching the leads on the fan side. But you’ll never have to mess with the battery balance terminals. It will always be the two outer ones
@@EastTactics You are correct sir. Your instructions work well for me and I have built my own dual-fan for my motor. I used the Integy 5th scale heat sink and it came with two fans but everything looks really nice including the mesh material dressing up the wires. I have the high-quality 18,000 RPM fans on order.
There's no link for the wire mesh that goes around the wires on the fan? You got a link for that? I think you said it was from Amazon but I don't wanna get the wrong size............ Thanks 👍
In the description there is a link titled “ High powered fan DIY” Let me know if you can’t find it. It is a list of all the goodies you need. Near the bottom you’ll find that wiremesh.
Did you order the Exact ones I sent the link for? If so I think I’ll probably arrive sooner than you think. Typically the stuff I ordered from AliExpress as a date it’s sort of out there but they surprise me more often than not.
@@EastTactics Yes, I ordered the same ones. I hope they come in quickly. I ordered several. This info is exactly what I needed for several cars. I’m done with putting weak fans on my rigs.
I've been trying to get a soldering iron but the link to the one you put in the description does not have it on off switch on the keyboard it has it on the on a box that is connected too so is this even the same one cuz I want the one that you had looks like it works good but it don't look like the same one when you click on a link you provided not saying it's not they just didn't look the same the one in the link has a big Orange box that sits there I didn't see that with yours I'll switch on the cord the one in the link it has an on-off switch on the base
@@EastTactics thank you sir yeah that looks better the one that's in the video the link goes to a different soldering iron and I want to make sure I got the one you got cuz that one looks like it works great and for 20 bucks that's amazing thank you so much as always
I’ve always wondered if the Heatsink that I’m showing In this video could actually work for larger cans. For Example my motor is 42 mm approximately, yours is 56 mm. Would simply using longer screws that span the gap between the upper and lower sections make this heat sink still function on your motor? I should look into that.
i built the fans with crimping the jst connectors but everytime i unplug them either positive or negative jst connector pops out and i have to redo it so is it just like plug it in and leave it for good? or am i doing something wrong
What’s your method of connecting the red and black wire to the little metal thing is that snap into the black housing? Are you using a crimp tool? A lot of the JST connectors that I’ve hooked to my fans I’m actually come from a prebuilt JST. For example my stock fan broke so instead of throwing the fan in the trash I snipped the JST off and when I connected it to my new 40 mm fan I just soldered of the red and black wires together. The Jst portion was already created. If you have that option do that if you’re finding your custom jobs for actually reconstructing the jst housing is failing. I have recently run out of prebuilt connectors and so I did pick up a crimping tool and the actual components to make my own. So if that’s the way you’re doing it, I might have some tips for you there as well just let me know which way you are actually constructing it.
OK I reread your post. It sounds to me like you are crimping them yourself, and they’re just easily coming apart. I actually might know what you’re doing wrong. I was thinking about making a video on how to properly use the crimping tool because honestly it is a little confusing. Answer me this, do you set the little metal thingy when you’re about to crimp in the valley of the jaws or at the peak of the jaws? Are you questioning the construction of your crimpers because I’m cramping it doesn’t fold the metal over the way you expect it to?
@@EastTactics i dont use the crimping tool i use needle nose plier it crimps fine but it doesnt pull out the whole wire it rips it from below where its crimped the wire stays stuck and i always have to get it out
So the crimp job you’re doing with the pliers is providing a weak point and when pulling the JST out in tears the wire from the Little metal thingy. I call it metal thingy lol have no clue what it’s actually called😜
The only thing I can suggest, since I might be misinterpreting what’s happening, is to find an old JST connector in your parts graveyard and use it instead. If you instead need to build the JST connector yourself, I would suggest buying the recommended crimping tool. Sometimes, if the little metal piece is just pulling out of the little black housing you can take the tip of your tweezers and push the little black tab deeper down to prevent your wires from backing out. But it sounds to me like your wire is actually breaking below your pliers crimp?
When you add the balance connector to the switch, it has 4 wires. Then when you start soldering, there's only 2. How do we know what wires to eliminate?
@@EastTactics Cool, thank you. That's what it looked like in the vid but wanted to confirm. I have everything ordered now. Just time to play the waiting game, lol. It's been around 110-120 degrees where I live so the parts can't come fast enough... Have no clue how long Ali express usually takes, but fans say probably a month unfortunately. Thanks again for all your help man, I'm excited to throw these things together.
@@EastTactics for sure man. You're a life saver. I've got $100's wasted on crappy fans that barely do the job and don't last. Tired of that money pit..... Looking forward to this 👍
Yeah, I do have a set of the v5 arms. I haven’t installed them yet. You do need to pick up a V5 rear shock tower as I mentioned in that video you watched. I picked up front and rear carbon fiber shock towers from BasherQueen off of eBay. found it annoying that I had to order the red anodized caps for the front end. I also had to order the pins for the shocks. Other than that it should be a direct fit. Where exactly did you find the incompatibility issue yourself?
@@EastTactics well I was talking to some guys and they sold me that all I needed is the shock pins, not sure but I'm running the m2c droop screws and when I installed the rear arms the arm was hitting under the diff output cup. And they are sticking straight out lol.. Can't adjust droop but so much, and its not enough. Maybe its the m2c screws thats making it not work. Since the v5 arms have 2 holes for the shocks, supposedly the outer hole is for the v1-v4 setup. I'm kinda new too arrma and it seems like when they make new parts its always compatible with older models, but idk lol. Maybe you'll have better luck.
I was asking my buddy about his EXB droop screws, and he said they just look like regular old screws. You might be right about the M2C droop screws being too bulky. Yeah I think the reason why you’re running into your issue is because somebody misinformed you that the outer hole is for the V1 through V4 set up. My understanding is that the V1 through V4 shock towers with a longer ears that stick out are simply not compatible “at all” with the V5/EXB arms. Another thing that is interesting is once you do have the correct shock tower on it brings the hole inward a good inch. That combined with the fact that the setting recommended for the V5 and the EXB regarding which hole to use in the rear a arm, is actually the inner one. So the combination of the top hole being moved inward about an inch as well as using the inside hole on the arm makes for quite a dramatic difference then the V4 set up. Lastly… Regarding your drive cups rubbing against the a arm, that is interesting. The EXB arms are definitely beefier and look like they sit a millimeter higher or so. In my opinion don’t be afraid to take your Dremel and open that area up a bit. If you look at the rpm a arms they are completely open in that section, so I wouldn’t be worried about taking a Dremel and shaving off some of that plastic to give room for your outdrive. I do see what you’re saying though it does look like that Outer hole correlates almost perfectly with the V for a arms. Giving the impression that you simply could keep your classical shock tower and simply run the EXB a arms to that hole. I mean… It was Rich Duper bash and RC dude 81 who both told me that the EXB Arms require the EXB rear shock tower. I almost want to approach Arrma customer service and ask them if indeed using that outer hole makes it compatible with the V4 shock tower. It seems like either way some of the plastic needs to be shaved off though to allow room for those drive cups. At least from what I’m looking at. I plan on doing a full installation video on this when I get around to it. However I’m sort of in no rush because I kind of wanna wait for my old stuff to break before I throw in a hole New set of arms. The RPMs are just tank too! Lol Let me know if you figure out anything interesting on this topic, perhaps see if you can’t find out directly from armor if that alcohol is actually designed for V4 shot tower. I’m certainly curious.
Yeah TH-cam auto sets that. However I do have the option to go in and reduce it. So I’ll take a look at this video and maybe reduce it by a few. Thanks for the feedback
There is no voltage warning, or at least there’s no measures being taken that is outside of safe protocols here. The fans are rated for 12 V input power. And the 3S Lipo battery outputs 11.1. So there is no breach of warning here? So I’m not sure I follow ya.
I think Tim means by removing the two center wires and only using the corner/end wires, will you be draining only one cell instead of all 3 at the same time. If I remember the two corner wire will give you the full voltage of the battery and using say the two left wires will give you the voltage of one cell 4.2 fully charged.
Using the red and black outer wires drains from all three cells evenly. As the Mandalorian would say… This is the way. I think I actually just realized what he was referencing regarding his question. He’s concerned that he won’t know when the 3S battery gets below the low-voltage threshold. Read my response to him below now but I realized this. Basically you do need to make sure that this does not happen. But in my experience every single time I get back after about a session to check the voltage on my 3S battery. It’s well above 3.6 V per cell. I myself only on one battery pack to run my vehicle. In the future when I on two, and have an extended session I will be making sure to check the power levels of the 3S battery to make sure it stays above par. My guess though is that one3S battery at 850 mA is enough to run through 2 full packs.
I stopped in an Ohio hobby shop and bought a $20 something soldering iron, piece of junk melted the plastic handle off while I was getting the 2nd battery ready for a new connection.
@@EastTactics Working on a triple fan setup for my UDR motor. Was going to 12v with a separate 3s like you did, but with a low voltage cutoff in-line before or after the switch. Then I found the size fans I need in 24v. So now going to run my main 6s power to a LVC, then on/off switch, then the fans. I could have also ran 12v fans with a voltage step down, but I want to try the 24v fans first, seems less complicated lol
At 18:12, my 3S connector has FOUR wires, which ones do I need to delete?
Pull the center two out
