[@lramage]

I'm new to the RC hobby and this has been a great help. Thank you.

[@hybrid32494]

glad to help my fellow RC friend!! any question on anything im always here to help, even if that means writing back to your comment while I am on the bus going to work, LOL.

Dig the vintage Lunchbox in the background!

[@hybrid32494]

hey man! Thanks!! Glad you noticed that, I put it there on purpose, lol. I have another video on that exact lunchbox running a small 3S lipo and a Venom 13T motor, the thing hit 30 MPH, it was quite good. And no damage from the run either.

[@Otiesh]

Grate man! You have really answered my questions . I have to go and reset my RC. I was about to buy other shocks thinking they are the ones that are poor but truly you have answered it all.

[@hybrid32494]

glad to have helped you!!! which model are you working on btw?

[@Otiesh]

Actually. I was a victim of those poor aluminum shocks that you mentioned , So I just restored back my old Team associated stock shocks with 60 weight oil and they are doing much better. I am looking at buying Hot racing big bore shocks

[@hybrid32494]

Which team associated model is this you have? As I recall the factory team associated shocks on most of their models are very good, they almost never leak either (the alum body ones). I just checked out the hot racing big bore shocks on eBay and tower hobbies. Not sure of that brand honestly, if you can get proline brand ones, thats the way to go. Even stock traxxas shocks are not bad compared to many of those terrible chinese ones.

[@Otiesh]

It's an upgraded Team associated pro rally, sure these shocks had lasted for long 'till one shock started liking after a hard crash that broke even the front diff. I had just upgraded it with a Castle motor and Hobbywing ESC first run test when it crashed. Yeah! I saw them on eBay and I might go for them since I had upgraded my chassis with aluminum under protection and I wanted to get off from plastic shocks.

[@tomphillpotts]

Great video bro, nice one. I have watched other rc shock videos and they say if the damper bounces out with no spring on the shock that means there's too much oil. Now I see they are wrong. Very helpful.

[@hybrid32494]

hey bro! thanks for watching! LOL, yes, they are totally wrong! You want a little rebound of the piston without the spring. This also acts like a tiny progressive effect on the shock, you know.

[@cwatson42785]

Hey hybrid this is probably the best shock explanation videos on KZbin. Very well done, very professional. Added to rc playlist. Great job buddy. Hope you and your fam had a great xmas.

[@ryanwinder5479]

New to rc. Very good video. Simple explanation. Will subscribe

[@pbednar]

I have really bad RC car but after your guide it works much better, thanks

[@Cronicbarbarian]

7:00 They are "Friction Shocks" I believe. They don't use oil. They reley on friction of the piston and rubber ring. Thanks for the content

[@jayryan7473]

I'd be happy to try friction shocks. I'm so tired of messing with oil!

[@Bags2723]

I realize this video is a few years old bit it's one of the best I've seen on oil dampening and rebound. I purchased an rc truck for my young son for Christmas and after he busted a shock shaft on his second battery I realized right away that the shocks suck ass. I'd like to upgrade the shocks but since I'm new and still learning I was wondering if I can replace them with a different size then what came as stock. The stock shock sizes are 87mm front and 109mm back from eye to eye but I'm having a hard time finding those sizes. Will slightly longer or shorter shocks still fit on my truck so long as the shaft ends are still the same size? I'd really appreciate any help you could offer as you seem to have a great deal of experience. Thanks.

[@dominicfortner2795]

Hey hybrid I have a question what’s the length of the exceed shocks I can’t find it anywhere thanks

[@bishopnick777]

Thanks for all the info very helpful man....

[@hybrid32494]

glad to have helped, thanks!!! which model are you working on?

[@richardcarlson1567]

Well done video! I'm cleaning up a Tamiya Neo Top-Force (item 57711) car that wasn't used much and has be in the box for 15-20 years I guess. Will be sending to our son for his boys. Checking the car out the front shocks didn't rebound at all. Didn't know the shocks actually contained oil - and when opened there was only a film of oil. I'd like to just put same weight oil in but don't know what that was. Hybrid - any thoughts on what the original oil weight might have been or a suggested weight? I already knew how to open the shocks but you did an exceptionally good video!

[@Ed-ty1kr]

Also, just because they are aluminum does not mean they are better, even if you buy the same design, and a high end manufacturer. The shock caps on the other hand, I would recommend aluminum, so that they dont pop off. As for the shock bodies, sometimes the composite or plastic high end shocks do work better. Especially on those super hot track days. Because after you run the vehicle for some time, the aluminum bodied shocks tend to heat up the shock oil, and thereby ruining your perfect setup. I found this out from the Team Associated rep... or directly from the horses mouth, if you will. After I asked why my buggy tends to loose it's compression and rebound effectiveness after a few minutes into a race. I even thought the first time this happened, that the oil was leaking out somehow, but it was all still there. So aluminum does heat up quite a bit, from the friction caused by heavy use, or if you live in Florida like myself. And when constituency is a key to victory, a car that behaves differently at the start of a race, to the crucial last few laps. It makes a huge difference.

[@Nio_music_]

My rear left shock is stuck do I rebuild it

[@streetshots1274]

Axial SCX10 already leaking in the rear. Only had it about a month

[@hybrid32494]

hey dude, that sucks. Open the shocks up and check if any of the rubber O-rings are binding. Sometimes a rebuild will help. Just check for any damage the shock seals at the bottom.

[@DNRailworks]

Thanks for this video, i recently got a Rustler and Tmaxx, he said he rebuilt the shocks but the backs on the Tmaxx dont really go back up at all, i know the weight of the engine and all but im going to redo them!

[@jonathankoh3118]

Hi Hybrid32494, u said that if a RC car doesn't bounce much from a landing, it is good. how do you achieve such results? what wt oil were used? thanks

[@hybrid32494]

hello, thanks for watching!!!. In general you want the shocks to absorb any impacts and not bounce up and down with a very springy type motion. I generally use 50-80 weight shock oils, depending on the shock types. Its really a matter of you doing trial and error with each shock you have. Some of the cheaper RC brands are unpredictable and have poor shock quality that are difficult to tune. Try your best to get it to not bounce and drive plush.

[@supboy666]

I have the gold shocks and the only thing i dont like is they dont have a propper bladder or bleed hole. I bought my Traxxas rustler 4x4 vxl of a friend with them installed and he didn’t know he had to oil them apparently. I felt the car really bouncy so i checked and they where empty. I oiled them and they work pretty good and better than stock except im never able to completely bleed em. Any tips would be good. Maybe using them without oil looses em up a bit then you throw in some oil and they are set lol

[@wdavie27]

hiya iv just purchased the wltoys across and going to fill the shocks with oil but can you or anyone tell me what size of Orings I need to Bay for doing the mod

[@SnoopyGSX]

Hey hyrbrid32494 nice break down video! Maybe you can help me....I've purchased 90mm shocks for my Traxxas Broncho and I'm trying to oil them up before running them, but after thinking I have all the air bubbles out I'm still getting "bouncy", and squishy reload. It looks like the truck has hydraulics. I'm using 35weight oil. If I fill them up, as seen others do, the shocks don't bound at all...stiff.What am I doing wrong?? Speak to me ole' RC wise one...you're my only help. Thanks

[@hybrid32494]

Hey buddy, I have been called an RC GURU b4, lol. Honestly the air bubbles are not a big issue, I don't really even worry about them much. Are you filling the shocks up near the top, but still gotta leave some room on top for the little rubber bladder piece attached to the shock cap on top. SO when you say bouncy you mean that it is not dampened enough?? If that's the case, you need heavier shock oil. 35 weight oil is really light stuff, try getting any 80-90 oil. If that is too thick you can always mix the two, they are all mostly silicone oils anyway, should be fine. I do that.

[@Obsequious1]

I use DOT 3 brake fluid. Works very well.

[@andyprairiedog]

Nice...how has the DOT3 held up since this post? Looking into using that as well for my (beginner) Blackout XTE shocks. I have bought new shock sets but now thinking of going into the 'rebuild' realm.

[@Obsequious1]

@@andyprairiedog holding up very well.

[@SolRC]

brake fluid is pretty hygroscopic and terrible for the environment, please pay a nickle extra and use silicone shock fluid in your rc shocks

[@TheACCmy]

Great explanation, im new to this. I saw that some oil have ratings but you didn't talk about it. All silicone oil are 1 kind?

[@acche-rc]

was hoping you can provide some guidance on how much weight to use for what type of car/truck

[@hybrid32494]

hey buddy! That is a good question, a good starting point is to find out what the stock shock oil weight is that comes in the RC from the factory. Based on that you can see if you want more or less dampening, you know? It's not really a fixed method because most shocks can also be tuned with various pistons that will control the rate of oil flow, so alot of variables there. Best to know the stock rated oils and go up about 10-20 weight at a time, until you're happy with the result.

[@alexmay9284]

I have GTR shocks on my Traxxas Revo and it has something like a nut in the bottom of it ( not the main cup on the top side of the shock!), and if I tight it well, the shock is not rebounding! What is the correct tight position of it? If I lose it, the shocks start rebounding. Guys, please help! Thanks!

[@justiceonly9105]

Hi, Very grateful to you.

[@hybrid32494]

hey buddy!! thank for watching, glad to have helped.

[@MrRui33333]

Hello, I come for this reason ask for help from someone who knows, which is: about oil shock absorbers, ... once bought a pack of 4 or 6 bottles of 60ml with numbers on its label that goes from 800 to 3000cst, .. I believe this is the name, and what I wanted to know is with the increase of such number (cst) the oil gets thinner, or thicker! overall and for 1: 8 and 1:10 scale cars of road, what would you advise? , .. because I think what I have very thick, though, that some say is also for differentials, if you can give me a help in this issue of damping oil I appreciate, .. thank you

[@queenjane7054]

I think HPI JUMPSHOT SC is built one of the best for the money I even changed out all plastic to aluminum upgrades

[@nikhilbhatt9114]

Hello Hybrid! I’ve been a subscriber for a few months now, loving your content. What brought me to this video is that I have a wltoys 144001. Just got it a couple months ago. I’ve probably had 15 runs with it and the shocks have begun to leak. What do you recommend for that car ? The shocks out the box were awesome, but over time the rear ones have begun to leak. What oil do you recommend ? Thanks!

[@jayryan7473]

Some people set the bladder inside the cap before screwing it on. Does this really matter?

[@hybrid32494]

hey dude, I've done both. It really does not matter, as long as the bladder stay in position correctly and you don't loose much of the oil you put in. thanks for watching.

[@EXTREMERC416]

Well i will say they are no so bad shocks maybe its hard to move the shock but it acts like oil would do no?

[@dannymcdonald1591]

Hello what would a 40wt b like

[@matthewneufer1758]

You can put sicolone oil on the shaft and it will make it smoth

[@brandonbentley8532]

The gold shocks might have been built with the wrong Orings, making them tight on the shock shaft.

[@hybrid32494]

hello, the gold shocks are terrible. THey were included for free in some eBay auction I bought, I'd never buy non brand name shocks. lol. But yes you're right, if the shocks don't leak and the oil is proper viscosity there is no need to rebuild. thanks for watching!!

[@brandonbentley8532]

I love tinkering but ive learned to not fix it if it isnt broken. The shocks may have been free because the previous owner didnt know how to fix them.

[@Lucas.stalcup]

I though when the piston came back out that meat it has air in it

[@hybrid32494]

hey bro! To be honest with you I don't really care about the tiny amounts of air bubbles in there, this is the most normal and reliable method on filling shocks with oil, you wont notice any differences by removing the tiny air bubbles, this takes time and effort. The rebound as I showed is adequate.

[@Lucas.stalcup]

Thats how i do mine.i have a rustler 2wd and typhon 3s blx 4x4 and a outcast 4s blx 4x4.ive never had a nitro rc but love your videos

[@alexkayman8483]

Wow. Those little toy cars are so complicated. I am surprised.

[@hybrid32494]

hey man!! Yes, there is a lot of engineering involved in these models to make them driveable at high speeds. Some can easily do 50-65 MPH with no upgrades at all, right from the factory.

[@luis.uet124]

Toy?

[@firstnamebunchofnumbers]

That’s why we don’t consider these ones toys. These are hobby grade.

[@chrisfarrell6470]

The gold shocks loosen up after you put oil in them.

[@JoseMorales-xz1tt]

Can I use any oil man? Lol

[@hybrid32494]

you can use any RC quality silicone based oil (that is the most common type). If you mean use engine oil or something like that, then theoretically yes. Ofcourse you would not have the same handling characteristics as RC specific oil viscosity blends. What type of oil are you trying to use?

[@queenjane7054]

Traxxis is to EXPENSIVE for all that plastic

[@hybrid32494]

hey!! thanks for watching!! You're right. Their shocks are quite cheaply made. Although a simple aluminum shock cap upgrade makes them pretty good instantly. I gotta say though, they could definetly be worse, too, LOL.

[@jordanonate8995]

Awesome...hehehwhe

[@hybrid32494]

thanks!!!! You into RC too? what kind do you run?

If your shocks arent leaking dont rebuild it, only change oil.

[@Sulphursprangs]

Na bro disagree with u on that many great reviews on those shocks dont leak either

[@TJ-jq9ee]

I find 2 stroke works best

[@hybrid32494]

hello buddy, thanks for watching!! Do you mean you like running 2 stroke nitro motors? or do you mean that you use 2 stroke oil additives to rebuild your shocks??

[@TJ-jq9ee]

I use 2 stroke in my shocks im riding on flat track with the odd jump there and then and its what I find best so far.

[@hybrid32494]

sounds interesting, I've got some 2 stroke oil, ill give it a shot. thanks!!!
