Upgrading the Tamiya DT-02 MS Sand Viper and the Tamiya DT-03 Racing Fighter 2WD 1/10 Buggy RC Cars with a couple of affordable SUMO brushless combos and digital servos from Yuki Models. Well, and then some steel pinions and my favorite set of tires and wheels.
The DT-02 MS in the video features several upgrades from Tamiya and 3Racing. The DT-03 Racing Fighter features several upgrades from Tamiya and GPM Racing.
From the looks of it, the brushless motor, brushless ESC and digital servo seems quite generic and resembles products from similar Chinese brands such as Surpass Hobby, GoolRC and the likes.

Upgrade? ... or rather downgrading the electronics from some rather expensive Tamiya-stuff, hoping that these cheap brushless combos and servos will be a better match for my two favorite 2WD entry--level buggies? Now I should be able to run them with some peace in mind.
Looking forward for some acceleration and torque with the high RPM and the lower gear ratio option, the 17T pinion. Worked really great with my last 3500 kv motor in a DT-02.
Also changing the tire and wheel combo on both units to my favorite set: The Tamiya DT-01 narrow off road front tires and the square spiked off road tires coupled with the Tamiya Star Dish Top Force / Astute wheels, front and rear.
This set up should also make it possible for some good comparisons. DT-02 versus DT-03 ... 3Racing upgrades versus GPM Racing upgrades ...

Also, can i suggest you cover that exposed bearing in the end of the motor, with a small square of duct tape or a decal or something. Why they leave those exposed like that I can't understand. Before i started covering my ones, i often had to pull motors apart to clean and re oil bearings. Now i put a small drop of oil on the bearing, then seal them up. Nice video, as always 😁

@NordicRC Год назад

Hi Pete! Uhh! That was a good tip! I would probably only have thought of that after seeing it filled up with dirt and dust! Thanks! That deserves to be pinned. I wonder if there is any way to make it look pretty … might ruin the looks. But better that than the bearing and motor in this case.

@madsrcbuggy Год назад

What a great tip! I have had a bearing seize up after a muddy run, on a motor similar to this, I will definitely keep this in mind in the future!😀

@peteuncle2935 Год назад

@@NordicRC you can use a nice small Tamiya decal left over from a kit to cover it 😁 A cut out circle of black duct tape you would not even notice with your motor colour. I used silver tape on one of my blue motors, and it matches the alloy bling bits on the car.

@Tamichtube Год назад

Wow I never noticed the sticker at the bottom of my 3300kv motor actually covered a hole. What a weird design choice, must be because it's cheaper to drill a hole instead of moulding it to hold the pin.

@peteuncle2935 Год назад

@@Tamichtube yes Tim, i have seen some of the earlier hobbywing motors, and I'm sure others, did in fact have a sticker over the end bearing from factory.

@johnellefa Год назад

You keep convincing me to pick up one or two It's amazing how good and affordable this kit is

@NordicRC Год назад

Yeah, both the Racing Fighter and the Sand Viper are great value for the money. Tamiya-wise at least. Love them. Years and years of fun.

@MarkBryanRC Год назад

Hi Mikael! I see you have been spoiling your lovely pair of DT's with some new electrical equipment! And what a beautiful 😍 pair they are, too! The new motors should add a bit of pep to their performance, I'm sure we'll find out soon. Hope your Sunday is going well my friend, all the best from Mark 👍

@NordicRC Год назад

Hi Mark! He he, yeah, but I wouldn’t say spoiling. It’s more of a down-grade. They were spoiled by those expensive Tamiya brushless motors and ESC’s and Sanwa RC. Now they are ready to run and fly without me being worried. The MS needs a pair of cheaper shocks too though before I’m happy. A bit more RPM too with the new Chinese motors. Hope it isn’t too much ☺️ Ohh, well, if it is, I’ll have fun changing them next winter again 😅 Best of Sundays to you too, Mark. I’m sitting inside and enjoying some Hopper-time.

@madsrcbuggy Год назад

Oh, that was nice to watch, as always, Mikael! I really like how you illustrate how versatile the hobby is, all those little choices that affect how the buggy is, it's great fun!

@NordicRC Год назад

Hi Mads! Yeah, it’s fun messing around with different set ups. With the DT-02/03 I usually change them every winter. Not sure if they get any better but at least I’m having fun trying out different stuff ☺️ Thanks for watching, my friend.

@NordicRC Год назад

Uhh. And hello from your old country: it’s a sunny Sunday today. Beautiful.

@mattiasrc Год назад

@NordicRC Год назад

Thanks my bro! Yeah, looking forward to the spring now! ☺️

@marresjepie1887 Год назад

Oooff.. vèry purrdy alu goodies. Fighter body in blue metallic looks actually way better than the stock orange. In my experience, the Sumo stuff is simple, no worries, and pretty sturdy at that. I use the simple 12kg Sumo servo’s in both my Wraiths without much issue. The longer DT-03 chassis is better at speed, I found out. It stays reasonably controllable, even with mad 5.5t BL motors. The DT-02, on the other hand, is a bit more twitchy, and really likes shorter circuits with a lot of sharp corners. Both are great entry vehicles in their own right, though.

@NordicRC Год назад

Very cool to hear! Hoping the motors will do good. I haven’t actually run them yet, waiting for a good occasion where there is time enough to take them both out and feel the difference. Thanks for the interesting comment bro!

@K-Anator Год назад

The DT-02 is so much fun with a brushless system in it. I stuck a Gool 4300kv kit in mine a while ago. I'll see if I can't dig up an unlisted video for ya.

@K-Anator Год назад

Yea there we go. Last winter with the Gool motor/ESC, 2SLipo, and some home made snow tires. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Nh3WAIsKZzc.html

@NordicRC Год назад

Nice! Yeah, love the DT-02. Got another Viper with a 4700 kv in it. Crazy fast just on 2S.

@K-Anator Год назад

@@NordicRC I wound up having to make a skid plate for this guy out of Meccano; I've just about worn away that back screw on the transmission from the wheelies. Apparently this system is 3S compatible, but given I set the same ESC on fire last spring by getting it wet, I'm not sure I wanna dump that much power through this one. Not to mention I already struggle shoving a 5000mAh 2S hardpac in there.

@robbrennanrc Год назад

Very nice upgrades Mikael. But for me I would have put the black wheels on the DT-03. But they both looked fantastic with the bodies on.

@NordicRC Год назад

Hi Rob! Yeah, they do look good. But prefer the white. Got another Racing Fighter with the black wheels though ☺️

@Pablo668 Год назад

Two very nice chassis from Mr T. Love the selection of bling on them too. What is that front end on the DT-02?

@NordicRC Год назад

Hi Pablo! Thanks! The DT-02 got a lot of bling from 3Racing. Out of production sadly.

@Pablo668 Год назад

@@NordicRC oh bugger.

@Tamichtube Год назад

Great build video, I noticed at 5:50 you had white grease around the pinion and spur, which grease is that? I'm pretty new at RC and usually run that part dry since the cars I had are like that stock,so I'm curious to learn more about the pros/cons

@NordicRC Год назад

Hi Tim! Thank you! I use Tamiya grease. Both Tamiya silicone and Tamiya ceramic grease. On open spur/pinion gears I run them dry too. But on these sealed/closed gear boxes I add a little. Can’t use too much though. Excess will be thrown off to the side when running so it’s bullet proof.

@camrowdrone6497 Год назад

😃 Enjoyed

@NordicRC Год назад

Thanks for watching, my friend!

@tjohanne Год назад

Beautiful. But isn't it better to just throw in a cheap speed controller that handles 3S and a 3S battery. The old silver can handles 3S great (but I did put one on fire in the Lunchbox, having bigger wheels and that).

@NordicRC Год назад

That could do yes! Like a cheap hobby wing brushed ESC. I do have brushed silver can DT buggies. But brushless motors are still more efficient, less battery-hungry and cooler on a hot summer’s day ☺️

@tjohanne Год назад

@@NordicRC Yes, I agree. I think it's a pity that the standard Tamiya speed controllers don't have a LIPO cut-off.

@BasBoyRC Год назад

Will be interesting when run which one is better and how good those Sumo motor combo are.

@NordicRC Год назад

Hi Mal! Yeah, it will be a good comparison set up. Only problem is that the Tamiya DT-02 MS shocks are way better than the GPM Racing. And yeah, crossing my fingers on the Sumo combos. But at least they are way cheaper to replace than the expensive Tamiya combos that I had in these last year.

@BasBoyRC Год назад

@@NordicRC Tamiya is not cheap when it comes to electrics. But it will still be an interesting test as the DT-03 chassis is different.

@DemiWorks Год назад

I see a lot of GPM parts... You're happy with the quality? I have some GPM parts on Axial cars, and their usefulness is - well, limited, sometimes to the point of "they could never have tested this on a rolling chassis". Hope they have a better fit on the DTs.

@NordicRC Год назад

Yeah, the alloy GPM for Tamiya is usually a good fit. Well, apart from the GPM shocks you see on the DT-03 here. Completely useful out of the box.

@IowaBudgetRCBashers Год назад

Which one do you like better??

@NordicRC Год назад

Must say I’m pretty attached to the DT-02 and the Sand Viper body. Got three of them now. They are pretty addictive 🤭

@IowaBudgetRCBashers Год назад

@@NordicRC I love how my dt 02 holiday buggy. It handles so well.

@ktu831112 Год назад

Where can I buy the blue option of DT-02?

@NordicRC Год назад

Second hand I’m afraid … it’s mostly 3Racing parts that are out of production. The GPM racing alloy on the DT-03 are available though.

@justinsmagula9579 Год назад

Where you get the ESC combo

@NordicRC Год назад

Bought them from Tamico in Europe some years ago. About 60€ for a combo.

@bradkalman2353 Год назад

These will be silly fast with that brushless systems.

@NordicRC Год назад

Hopefully not silly fast ☺️ Got a Viper with 4700 kv and 19T pinion that is silly fast 😅

@bradkalman2353 Год назад

@@NordicRC I had 4600 castle but couldn't use it in any my Tamiyas. I think I could have used a different company's system cuz I would think would have less power than theirs of the same type I couldn't use it in my super hot shot.

@paulv4130 11 месяцев назад

Why wouldn't you just get an associate B6?

@NordicRC 11 месяцев назад

Yes. Only somebody with the ‘Tamiya-bug’ can understand why 😉 No rational reasons. Only emotions.

@bradkalman2353 Год назад

How much for those systems USDand do they sell them state side?

@NordicRC Год назад

About 60-70 usd. They seen quite generic, so probably very similar (or identical) to other Chinese combos in the same price range.

@bradkalman2353 Год назад

Please do GPS tests on them.

@NordicRC Год назад

I will come spring ☺️

@davidhumble6892 Год назад

I can honestly say that these ESCs are trash. I have had 3. 2 needed to be returned as they didn't work and 1 died after 2 runs with it's paired motor and only 2s lipo.

@NordicRC Год назад

Uhh, doesn’t sound too good at all. Hoping mine will be alright. Got some other similar Chinese ones that still work fine.
