Tamiya DT-03 Racing Fighter: Assembling & Testing the 3Racing Shock Upgrade!
ฝัง
- เผยแพร่เมื่อ 4 ธ.ค. 2021
- I'm a bit baffled and shocked, to say the least. These where marketed by 3Racing as the World's Best RC Hop Up Parts. Let's see about that. Here's an assembly and test of a brand new set of 3Racing DT-02 Shocks - on the Tamiya DT-03 Racing Fighter 1/10 2WD Buggy RC Car ... versus the GPM Racing Shocks from the last test, the stock CVA shocks on the Tamiya DT-03 Neo Fighter Buggy and the original DT-02 MS Hop Up Shocks.
Are you shocked too? Would love to hear what shocks you are running your DT-02 or DT-03 with, in the comment section.

The plan is actually to remove most of the DT-02 MS parts - and re-use these in another project. Already got some new parts from both Tamiya and more from GPM Racing. Hopefully it will turn out better than this dreadful start. But hopefully it will save somebody else, watching this video, from wasting money on these shocks when upgrading the DT-02 or DT-03.
Off camera, I did try to mess around with both oil and springs. The tricky part, I found, is that both the GPM shocks and 3Racing shocks do not fit the usual Tamiya shock diameter . And that left me with little choice of springs - as most of my spare parts, including my springs, are "Tamiya-size". If anyone knows where one can buy other (softer, shorter) springs that are suitable I would love to hear about it.
And well, even though the 3Racing shocks are approx. half-the-price compared to Tamiya's own aluminum hop-up shocks for the "D-buggies" (DF-02, DT-02, DT-03, DF-03) - the performance, as you can see in the video are worth every penny. From a far it's hard to see the difference. But what a quality difference of the parts. Especially the shock bodies feel so different. And the assembly and fitment of the parts are again so different. Everything is just so much better when it comes to Tamiya. I would even call the stock CVA shocks a hop up part compared to 3Racing and GPM Racing.
And no: I don't suspect that a battery in the car during the tests would make any real difference. Maybe a heavy old 6S 6000 mah NiMH might make a difference, but not a light modern 2S LiPo.

Hiya Mikael. Oh wow so it's the same old story of the after market shocks not being suitable for the Tamiya buggies. I actually went back over the footage after seeing the result to see if I could spot anything you did wrong with putting the rear ones together. It looks like what was happening with the FAV I have with the Wild One shocks being bouncy. It was because the piston tops were not a snug fit in the shock body. Once I found some better ones it was perfect. If they are already snug then maybe a piston top with fewer holes and/or thicker oil? Just shows that although the plastic Tamiya CVA shocks aren't pretty, they do the job very well. Also I don't think I've broken any or not many anyway. Great vid my friend. Must be frustrating for you if these were bought with your own cash rather than being sent for review. Hope you are having a good Sunday. Cheers for now :-)
Hi Pete. After seeing the bounce I checked all again. These where build exactly after the instructions. If it is the stock piston tops that are wrong it will be quite hard sourcing out some that fit perfectly I think. I only got the Tamiya ones to try out. But I could check and maybe try out some others. An extra set with 2 holes are included. And maybe with some Tamiya oil. But the springs are still hard. But yeah, CVA shocks for the win again. And yes, everything was bought with my own cash. I could have bought a set of Tamiya hop up shocks for the price of the GPM Racing and 3Racing 😅 Anyways, thanks for the input. Maybe if I find the time I will try to tinker with these again.
And cheers, my good mate. Hope your Sunday is good.
@@NordicRC Yeah good so far thanks. The sun just peeped out from behind the clouds so I have put some lipos on charge but I expect the sun will be back in by the time they are charged. Want to do some more testing of my 6WD Volvo truck. First test run was great. Enjoy your day. Hope you can get those shocks sorted. What a palaver!
Great test, that shows again, that the original shocks are pretty good! No need to change !
Yeah, no need to change 😊
Hi Mikael. Sorry for the late watch but never saw a notification. Anyway I think I will stick with the stock shocks on my two DT-03s. Many thanks for taking the time to show us all just how awful some supposed hop-ups can be. All the best and keep safe my friend.
Hi Rob! Yeah, good idea! You will be pleased to see the next hop-up then 😂😉 All the best my good friend.
As I mentioned in the last video, I had the same results as you. Went back to the CVA's, then pushed the boat out and got DF-03 Alu dampers, which as you know are superb. I guess you get what you pay for. Awesome video as always, you will save people a lot of hassle and money.
Hi Matt. Yeah, I hope it will come to people’s aid when they are looking for their first hop ups. And yes, all my Tamiya hop up shocks works great for both the DF-02, DF-03, DT-02/03 and TT-02B. Just superb. I might go back to the CVA’s on this one though since I just wasted all money for it on GPM and 3Racing 😅😊
i'm very shocked about these shocks. What a shocker these shocks are
Yes, shocking bad performance on a DT-02/03. Should never have been marketed as suitable for these light cars. I suspect they are even to hard to work properly on a TT-02B too.
Just use the CVAs, they're dirt cheap an work perfecly fine and better than all aftermarket shocks together.
Only option beside the CVAs are the Tamiya HopUp Option.
Yeah, CVA’s all good! What a coincidence. See today’s video. I figured since I had them I could make them work. But still not recommending them.
Great example of how bad some of the aftermarket shocks can be 🙌🏻 I have been using some from JK-RC for my CW-01 and they have been very good. I have some for my Rising Fighter project in the summer and we’ll see how they go. Worth taking a look at their shocks 👍🏻 Great video as alway 🙌🏻
Hi thanks for the tip! JK-RC. Never heard of them. But thanks. Uhh, the Rising Fighter is so tricky. So easy to get too hard shocks for it. The CVA’s I got on mine are way too hard at least.
I never changed the shocks on my DT-03. After 3 years of really hard use, they still work like on the first day. No need to upgrade them from my side.
Yeah, I still got them on my first DT-03, the Neo Fighter in the video, as well 😀 works great. Just fun to try other set ups and hop ups for the other one, for the project itself, but also just to have two very different ones.
Thanks for sharing this video and experimenting with these aftermarket shocks! That's spot on-I had bought a GPM set for a project and it was terrible (even with Tamiya oil). Only thing I could think of is replacing the springs but I didn't even bother and ended up not using it. I would assume even the 3racing ones wouldn't be any better and glad you tested it. I think I'm taking a break from these aftermarket brands for a while.
Hi my friend! Great to read you here. As you know I enjoy your videos very much. Yeah, I think there will be too much invested trying to purchase some springs in the right diameter, softness, length. All my Tamiya springs do not fit. I had high hopes for the 3Racing at first - since in photos they look like identical copies of the Tamiya hop-ups. But sadly the combo of wrong springs and bad quality make them pretty much useless. I think I am taking a break too from these after market brands. Especially the shocks. Got some good machined alloy parts from GPM and 3Racing. Maybe they should stick with that and don’t try to make shocks, as apparently they have no clue what makes a good shock. It has to be tuned perfectly to the specific car. Springs, pistons, shock body length, oil etc.
@@NordicRC Thank you! Good to know the Tamiya springs don't fit. I wonder why they didn't make the shock body diameter more universal. I agree with you and maybe they should just stick with the alloy parts. I do like them and still continue to use them. Anyway, thank you for making these great videos! - Marc
nothing wrong with using 3racing shocks just need to buy better rear springs i used team associated #1582 tuning kit 2.10 spring rate. i built mine using the 2 hole piston tops and using TLR 70wgt oil and im very happy with the results !
Hi Cameron! Sounds like some good tips. They certainly need some adjustments. Yeah, especially the springs.
Thanks for sharing your test video, I hope you find the right hop up shocks. Great looking buggy too👌🦘🇦🇺
Thanks bro! I hope somebody who is thinking about buying these watches this video. And I hope I find some for my Racing Fighter some day 😊
@@NordicRC
I hope you find some!, they're such a nice looking buggy, I've never driven one but hope to buy one some day and get to try it out.
Oh boy, thats unexpected! Tamiya CVAs for the win!
Yeah, well, I had a couple of warnings in the last video, but still disappointed ☹️ But yeah, CVA still wins
Great shock comparison Brother! I Really like the blue that you chose for that model, it's a beautiful color! I really prefer building kits to RTR's because you typically end up with something higher quality and something that you can take pride in from building it but RTR's are fun to get going right away 😁💯🤜🤛🔥🔥⚡⚡🙏
Thank you, bro. My favorite color: Tamiya PS-16 metallic blue. Yeah, I like both kits and RTR’s. All fun 🙂
Nice work Mikael the DT03 is looking sharp i think i might build one after Christmas
Hi Brent! Thanks! Good idea. Just use the stock CVA shocks. They work better than most of the after market shocks,
super nice! you are super close to 20k subs!
Thanks bro! Yeah super close 😊
I have a set of these for the TT02b. I used the Tamiya oil in them that came in the kit. They’ve been good for like 3 years now. I don’t know about the oil they come with though. I chucked it. The springs on mine were softer though. I guess I got lucky.
Yeah, I think they would be better on the TT-02B. A heavier 4WD buggy without the rear mounted motor. Think I will try to mess around with oil too.
Spot on
Hi Anthony! Thanks for watching
Nice share, stay connected, good luck further!👍
Thank you!
Informative video here. It is nice to see, that Tamiya standard shocks are better, no need to invest into tuning one.
Hi Milos! No, the GPM and 3Racing might be more durable, but performance wise worse. The Tamiya hop up shocks work sweet though, but cost about the same as a whole DT-03 kit 😅
Another great video 👍 hope you are good? I’m finding using the Tamiya shock oil in a £20 set of aftermarket shocks from Blacksmith products soaks up the terrain well. There soft but keep the back from bottoming out as this besides the nose are the weakest spots on this chassis. I’m on number 3 chassis 😆 for my Neo fighter I give a hard time to and have a really nice racing fighter on the shelf. Thanks 🙏 for another great review and have a great Sunday I’m going to try out this TT-02b I’ve fixed up 🙏
Hi bro! Good tips. If I hadn’t just wasted the last money on these sets of useless shocks so would try them out. And yeah, front shock tower and front chassis likes to break 😊 So far I’ve been lucky. Or maybe I haven’t run them hard though 😊
Cool with the TT-02B. I’m fixing up some DF-02’s at the moment. All fun 😊
@@NordicRC yes all good fun 🤩 hope you had a good weekend? I managed to test my TT-02b yesterday and she goes 💨💯….enjoy your df-02’s 😎👍
As you say, it's shocking! Goddag, Mikael. Haha - "A Grasshopper"!!! What a shame, they look so nice, but I'd rather have plain looking shocks that work properly than bling that doesn't, and I know you feel the same! I run the stock CVA's with stock front springs and harder rear springs on my DT's. I also have a set of HobbyKing alloy shocks on my DT02 that were only about 25 Euros for all 4 (but using the standard kit springs on the front, which fit perfectly). I'm very happy with the performance of both, with the alloy shocks being only a little better. Great video and very clear demonstrations of the shock performance. Have a great Sunday, my mate!
He he, that was for you: Grashopper 😊 Knew you would like it. Yeah, on this one, which is a runner I definitely would like some shocks that work - more than the bling bling. But you know me. I prefer both - especially when I already got my other DT-03 with the CVA shocks. It’s always fun with different set ups. If I had any money left I would try those hobby king ones. But just wasted money on two alloy shock sets for this one. Might try to mess around with pistons and oil. Thank you so much for watching my mate and for the tips. Hope Sunday is treating you good.
@@NordicRC Hehe, thanks mate, "Grasshopper" - you know me too well!!! :D
The way that rear end just bounces makes me laugh 😁, great comparison video👍
Ha ha, yeah, not exactly optimal. Will be as difficult to control running like one with pogo sticks and non-oil filled dampening.
And thank you!
@@NordicRC No problems 👍
I think I will just stick with the stock shocks 😂😂
Good idea! They work splendid with the right amount of pre-load.
@Nordic RC Visions. Great test. How many mm are the spacers on the original rear shock absorbers?
Hi. Thank you. Not sure.
LOL I knew the result before you started. Got a set with a car I brought not fitted but they were included I wonder why.
Ha ha, yeah, better leave these in the box. Waste of money, unless one could find some other springs that would fit. All my Tamiya ones do not fit again.
Oh... What a hassle finding proper shocks, I'm almost scared of even trying any aftermarket shocks... Good thing the old CVA's are included in most kits, I been happy with them so far...
Your video got me thinking, do you have any weight added to the front of your DT-03? On mine, I have two brass slabs, 28g each, with velcro tape on them, so I can move them over... I guess that might help on the front... But the rear... Damn... Did you try add more preload, or change to heavier oil?
Anyway, was really nice to see one of your videos again, I believe it's been a while?
Hi Mads. Yeah, what a hassle. Wasted my money so far. For the price of the GPM and 3Racing I could have gone straight to some Tamiya alloy that usually works. And yeah, the good old CVA’s usually work. Nope, no weight. I remember I really wanted to do something on one of my DT-02’s once. But couldn’t find any way to hide the weight properly. But yes, it’s a good idea with these. Will get rid of some of the understeer. And no, not tried anything yet. Well, off camera I tested the diameter of the springs. Too bad, not Tamiya-size. And yeah, preload just turned the springs to bricks. Maybe if I find time I will try to mess around with oil and pistons. Ahh, yeah, too little spare time. All house, kids and work these days. It will clear up in a few weeks 😊 But then the holidays are coming. So no time at all for the hobby 😂😅 It’s all good. Kids are the priority.
Did you try putting the white springs on the GPM shocks?
Hi David. Yes. All my Tamiya springs are the wrong diameter for the GPM shocks. Especially in the front. Got a lot of Tamiya spare springs and pistons so if they had fit it would be an easy fix - to mess around with springs and oil and pistons to make them work. But sadly not the case here. Would probably end up costing more in springs and pistons and shipping than they are worth - to make them work now.
Have you tried thicker Damper Oil, for the rear.
Should do the trick.
No. Not tried anything yet. Wanted to show these as they come, so people know what to expect 😊
@@NordicRC I see. I’m not sure why, they wouldn’t use or recommend, the correct Oil Weight in the first place, for the DT03 chassis 🤷🏼♂️
What oil weight did you use? Stock recommended?
I do not recommend the GPM or 3Racing. The stock plastic CVA Tamiya are better. And just with the stock oil, yellow #400.
I see what you have going here I think you could have tuned the shocks and got any of them to work better spring changes piston changes oil weight changes.
Yeah. But sourcing out the right springs and pistons would end up costing more time and money than the shocks are worth. Got a lot of spare Tamiya springs and pistons - but not the right size for the GPM. Anyway, this review was only for the stock set up. A lot of people buying these cheap types of shocks for a cheap DT entry level Tamiya, can’t easily or affordably fix it.
Very true.
oh no :D
Yeah, a shame these are marketed to suit the DT buggies right out of the box.
Hey Mikael. Great video. Yeah... chinese hop ups peculiarities... You could reuse kit springs, as they are very suited for DT03. I have bought several Aliexpress dampers, which look like you GPM ones. Total crap, but I managed to make them butter smooth with lots of effort and some investment. First, reuse kit springs. Then replace chinese o-rings with Tamiya red ones. Then polish shafts with 400 800 1500 sandpaper and then with paste. Lastly, adapt Tamiya pistons instead of crappy chinese ones. Result is great, but with that extra effort and increased price its better to get better Tamiya aluminum shocks or stay with CVAs.
Hi bro! Uhh. Some good tips! However, I found that both the 3Racing and GPM Racing springs’ diameter doesn’t fit the diameter of my whole collection of Tamiya spare springs. Especially the front GPM springs are much larger than Tamiya fronts. I haven’t tried the stock springs but I suspect the same. I think the springs are the main problem in both the GPM and 3Racing. I’ll definitely try to mess around with some things on the 3Racing ones though. Oil and pistons. Maybe they can be ‘saved’ 😀 I’ll look into your other tips as well. But yeah, better just go straight to the Tamiya hop-ups. Or just keep the CVA’s 😂
@@NordicRC Yes, springs' diameter is a bit bigger issue. I didnt mention, that I polish shafts on electric drill, and you can easily test their smoothness by gently pulling a bitten shaft through your teeth. You can feel the grittyness. Even CVA shafts are gritty. After polishing treatment, you can feel how smooth they glide over teeth :D P.S. you should try vintage Tamiya nitros, oh what an addiction I got with these fuelies :)
everything is labeled as "worlds best" these days. lol. i swear you'd have way less hop using basically any other shock thats not labeled for Tamiya. Thanks for sharing. your rig looks gorgeous! also, I would try it with labeled brand shock oil, like TLR or TA, getting something heavier. :) have a good day bud
Hi Bee! Ha ha, yeah, everyone is ‘the world’s best’. I like it better when brands slogan are a bit less ambitious. I will try with some Tamiya oil. Problem is the springs though. Not Tamiya size so I do not have any that fit.
Have a great day too, my mate.
I've got the 3racing shocks and they behave completely different on my DT 03, especially in the rear. Maybe it is a Matter of oil?
Maybe you got other springs or other oil or pistons? These where build according to the instructions included
Would love to hear what you have done so I can fix these 😊
But my thoughts are that it is the springs. Incredible hard.
@@NordicRC nothing really, they worked fine out of the Box. Very strange ...
Strange. I checked the footage to see if I did anything wrong after seeing how the rear shocks behaved. I couldn’t find anything that was wrong according to the instructions.
Ever thought of playing with spring rates different fluid for oil to get the results you want?
This video isn’t really about that. Many that buy these after market shocks doesn’t have a large stock of oil and springs. It’s an entry-level buggy. I do have quite many many Tamiya springs and pistons - but they do not fit these, either the GPM or 3Racing. So it would cost a lot of time and shipping money to source out different springs and pistons in the correct size, rate etc. - since GPM or 3Racing doesn’t offer any option packages like Tamiya does.
Thats some backwards engineering you have going on there, turning a racing buggy into a hopper LoL. But they do look good.
Yeah, sometimes upgrades works as downgrades 😅
Seems like the front springs are way to stiff and the rears need heavier shock oils. Hmm, at this rate might as well stay with the stock pogo sticks😅.
Yeah. Both the front and rear shocks are way too hard. Maybe the rear shocks could be saved with some tuning: oil, pistons. Don’t have any springs that for though (different diameter than Tamiya).
Those o-rings make it much more difficult to even screw it up or down.
Yeah! Such a pain to build. Some of the others wasn’t that hard, but the one I chose for filming was a nightmare. With Tamiya those o-rings fit perfectly.
That’s because you are supposed to put a dab of grease on them when you assemble them or you are dragging dry rubber over freshly cut sharp threads. I have to say that vehicle was not a very good test for those shocks. It looked so light , especially at the front I wonder if any out of the packet shocks would have any effect. Did it even have a nimh battery in I wonder?
I think they would be good on a 4wd with thicker oil and maybe the Tamiya springs unless running on carpet. I noticed there was no grease or shock slime put in the cartridge either. That makes a huge difference to shock performance.
@@neontetra1000 Ahh, yeah, good tip with the grease on the rubber rings. I guess I'm used to the similar Tamiya Hop-Up shocks, that are exactly the same but doesn't need grease - and everything goes well together.
Oil filled pogo sticks it's like you never took off the friction dampers.
Yeah, the rear behaves more-or-less like pogo sticks. Just the absolutely wrong combo or springs, pistons and oil 😅
The upgrade was a downgrade after all. I have one unused set of these but we'll see if they work at all. The first set was pretty awful when i tried them about two years ago.
Yeah! The upgrade was a downgrade. Even though they look bling bling the performance is not worth it. I’ve had a comment that somebody else had good luck with these. I think I will try messing around with oil and pistons.
@@NordicRC Mine had issues with the shock body not being round and got some friction with the piston. Three were good but one was pretty terrible.
