- In this video I build and chat about the DT-03 Tamiya Aqroshot RC buggy / short course truck chassis. Along the way I hope to throw in a few tips and show some of the essential hop-ups for this kit.
Many thanks my mate Rob @robbrennanrc who got this kit for me as a gift. Also a big thanks to Peter @cw-01creations46 for sending me the excellent Orion 12T motor and ESC.
About the DT-03 T kit:
This assembly kit R/C truck features a stylish body inspired by U.S. stadium racing trucks. Made from lightweight and durable polycarbonate, it features a rear wing, and can be decorated using the flashy markings included in the kit. The chassis provides suitably dynamic driving fun, and is mounted with front and rear wheels of differing offset, mounted with radial semi-pneumatic tires.
The stylish slimline form of this chassis stems from its lightweight yet durable monocoque frame, which features a longitudinally-positioned battery and the R/C equipment along the centerline for excellent balance. The combination of a long 287mm wheelbase and 4-wheel double wishbone suspension married to CVA oil dampers with long arms at a 25-degree attachment angle, allows the model to handle with stability on poor surfaces. The rear-positioned gearbox is sealed to protect from dust and dirt, with the built-in differential gear offering smooth cornering.

●Length: 425mm, Width: 298mm, Height: 143mm ●Wheelbase: 287mm ●Tread (Front/Rear): 251mm/243mm ●Tire Width/Diameter (Front & Rear): 47/84mm (Front) ●Monocoque Frame ●Rear Wheel 2WD ●3-Bevel Differential ●2-Piece Steering Tie-Rod ●Front & Rear Double Wishbone Suspension ●CVA Oil Shocks ●Gear Ratio = 9.28:1 ●Type 540 Motor ●Requires electronic speed controller (sold separately) - Auta a dopravní prostředky
Masterful as always Mark. Love watching your build videos chap! Looking forward to seeing the body creation dude 🙌🏻
That's very kind of you, Craig! 🙏 Glad you enjoyed it and hmmm... I'm still deliberating about the paint scheme! Have a good one matey! 😎👌👍
What a beaut! Your build are always so informative! Cheers!
Thank you kindly, Sir! Cheers! 😎🙏👍
Great video once again, Mark. You're really tempting me to grab one of these trucks. 😁
Thanks Fil, well you already know how good the DT03 chassis is and this version will hopefully be as good as that! The bigger wheels should be good out on the rough! All the best, dude! 😁 👍
Another brilliant video Mark. You have so much patience. Take care 😊
Awww, thank you my friend! Patience comes with age I'm afraid! Take care too, Kim, have a smashing weekend! 😎🙏👌👍
Thank You for the mention my friend 👍
My spidey sensors tell me that you might do a speed run with it soon 🤔
You are always welcome, mate! And thanks for the cool ESC and Motor! 🙏 Definitely be doing a speed test, gotta get that body done first though! Cheers my friend! 😎👌👍
lovely chassis to build and nice plastics 👍should be a good truck 👍
I agree with that, Dom! Yeah I think this should go well with that 12T motor and proper tyres! Have a smashing weekend, mate! 😎👊👍
Hi Mark, a great installation video of the talented DT-03 chassis. I like the way you’ve highlighted the design features of the chassis, those more flexible plastics, acting as buffers to the more rigid plastics. Lots of hints and tips too…a real experienced modeller at work, 😊😊. The DT-03 chassis is such a great beginners model,yet has plenty of hop up components as standard, and for the price, it’s amazing value. I’m interested to see how yours goes, with that AW grease acting as a LSD 🤔. Oh, pop some Team ZX-1 micro oil on those bearings 😊, makes them run really smoothly. 😊😊looking forward to seeing the Mark Bryan bodywork😊😊hope you and the family are keeping well, best wishes 😊😊
Hi John and thanks as ever! Yes I thought it would be a good idea to chat about the features of the design for a change, thought it might interest the RC enthusiasts like you out there! Glad you enjoyed it!
I agree, this chassis is perfect for a beginner but still has good performance even though it's a relatively simple kit to put together. I'm interested to see how it goes too, John! Fingers crossed. Thanks for the ZX-1 tip, I'll look out for that! All the best to you and yours too, take care mate! 🤗👌👍
I like the DT-03 chassis, although it does tend to understeer under power due to the long wheelbase. I had a Racing Fighter a couple of years ago, but I converted it to a DT-02 Sand Viper and added a few hop-ups, and it was awesome. It jumped well, ran well, and I didn't break anything on it. Oh, I also replaced almost all of the screws with hex-head hardware. Sadly I sold it as I needed the money at the time, but I'm so tempted to get another one. Awesome video as always!!
Hi Barry and thanks for the great comment 👍 I have to agree the DT03 does tend to understeer compared to the DT02, but with the Blitzer front tyres I reckon it might be a little better 🤞 I get 100 m3 10mm stainless screws for 3 quid, so it's a no brainer! Always room for another RC car, pal! Cheers! 😎👊👍
I love this chassis, it's so well designed yet totally beginner friendly. Really wish Tamiya would use it as a jumping off point for a new platform.
You and me both! Totally agree with your comment! This could be the focus for so many more cool RWD Tamiyas! 😎👌👍
I like it too. But it *lacks a slipper-clutch* ! Just not competitive enough for serious racing. Especially on a hilly course...
You make the some of the best build videos in the RC world. Most others are too "lazy" to video their build.
I just came home from Birmingham after visiting the Classic Car Show at NEC
I found some cool inspirations for painting some Tamiya bodies, including a Supra (A80) and a GTR (R35)
Did you see that awesome mechanical bull they have on display inside New Street station ? amazing!
Hi there Are! Well i must admit I'm very flattered by your kind words. I do try my best to make informative build guides, yes it does take a lot of effort but I hope it's worthwhile!
Wow, you came to Birmingham! Sounds like you had a great time at the Classic Car Show - definitely a good place for inspiration! Oh yes, that bull (made to celebrate the area called the Bull Ring in Birmingham) is a work of art for sure! All the best, cheers! 🙏😎👍
Nice build Mark , looks great again, good tips and tricks mate👍
Many thanks, Fons! Have a lovely weekend my friend! 🙏😎👊👍
Nice build and looking forward to see what you may do with the body 👍🏻
Thanks Damian! Yeah, still trying to decide what to do with the paint job! Cheers mate! 😎👊👍
What a great build tutorial again, Mark! I think these videos are really helpful, especially for newer hobbyists. And even though I like to consider myself experienced, I like to watch a few build tutorials before starting on a kit myself. Partly to catch the tips and issues beforehand, but also as part of getting hyped up for the build.
Another thing, you described it really well, the use of softer plastic to make it quite a durable RC. I had actually not thought of the way the gearbox was attached to the main chassis, it's quite nice!
Hi there Mads, yes this chassis design is pretty cool really! I'm the same as you, I enjoy watching a good RC build, even if its a chassis I'm familiar with! Glad you think mine was okay! Looking forward to seeing how this one goes on those bigger tyres! Cheers mate! 😎 👊👍
I tell ya this thing is looking Very Robust so far. great looking build bud. Mark you always do a great job on these brother. Well done
Thanks muchly my friend! It's turned out very nicely 👌 and should be a good runner I reckon! Your kind words are much appreciated, brother! Cheers! 😎🙏👍
Lovely build dude.. look forward to seeing how it looks with the body and some driving footage maybe a few jumps 😊😊 have a great weekend.. Pete
Thanks muchly my friend! Still deliberating about the colour scheme - any ideas?!?!?! Yep, i reckon this buggy will handle a few jumps well! Have a great weekend too, Pete! 😎👌👍
A great detailed build with great tips, I have racing fighter and think it's a good quality build kit, I put the traxxas 12 turn with a small mod and glad I did ,it does 27 mph but acceleration is really good, I look forward to Finnish and see you run this one mate, thanks for your upload 👍🙏🐱
Many thanks Cat! 🐈 That racing fighter of yours sounds awesome with that motor fitted! 👌 27 is well fast enough for an off reader. If mine goes as well I'll be chuffed! All the best mate! 😎🙏👍
great build marky very detailed tips n tricks keep up the fantastic content man😎😎look a cool buggy cant wait to see your magic on the shell 👍
Hiya mate, I'll do my best brotha 👌 Yeah this is a really cool buggy, should be a sweet runner I reckon! Hope Sunday is going well my friend 🙏 😎👍
Love how the servo mounts into, so much better design than the early little posts where the screws can come undone. Will be interesting how fast the motor will be in this, I find the DT-02/03 not that fast over the DT-01 with the gearing. I'm with you with the tyres, but you know my choice is Madbull 🙂
Totally agree about that servo mount, Mal. I think this should run quite well as the larger rear tyres will increase the gearing a bit! Haha, oh yes, i know how much you like those Madbull tyres! Cheers! 😁👍
@@MarkBryanRC 😁
Great build and tips Mark. Interesting that you limit the travel in the diff. I'll keep an eye on your running video. Oh I have a little one for you, too. The front c-hubs're to soft, better change them into metal ones😉
Thank you Sir! Yes, the AW grease really does tighten up the diff and helps with traction on a loose surface! Thanks for the little tip, noted! All the best my friend! 😎👌👍
Thanks to Rob for the kit, thanks to Peter for the motor and ESC.....
and a big thanks to Mark Bryan for another very clear and professionally presented build video.
Always enjoyable to see these kind of build videos on some of the more modern offerings mate.
As someone who generally sticks with cars from Tamiyas first 100 (up to 1992 ish) it's interesting to see how the design and the components have evolved over the years, different construction/build techniques are also very apparent.
Tamiya have made designs less complicated, lighter, stronger and more efficient.
This chassis looks like a good example of this.
Do you think that the anti wear jizz is of noticeable benefit?
I've got a huge metal tub of late 1970s Castrol molybdenum jizz that I've been using on everything since the mid eighties (new builds, restorations etc)..... I've never had any issues with it despite hearing it can attack plastics long term.
Looking forward to seeing this thing running fella,, I'm guessing it will be quite nippy nipsta with that motor, and a whole load of fun! 😂
👍 👍 👍
...and a massive thanks to James for another thoughtful and interesting comment!
Yeah I do like the contrast between the classic chassis designs and these newer offerings. Both have a fascination for me! I love the older, quirky nature of the constructions but it seems that Tamiya continue to be quirky in the modern day! Yes this DT03 is stronger and more efficient but does have some cool solutions to those issues. As for the AW grease, yes it definitely has benefits. For keeping joints sealed, it's unbeatable, it's like gorilla snot!!!! And in the diffs you can definitely feel the difference when driving.
I've used moly grease as a standard lubricant for many years and never had an issue with it damaging the plastics - hell, Tamiya even supplies moly grease in some kits!
Yep, hoping this one runs well, fingers crossed, fella! Cheers! 😁👊👌👍
@@MarkBryanRC
Quirky is kinda cool mate.....
I may well get something more modern, one day..... but for now there are too many boy hood dreams that require the Tamiya tokens! 😂
I do very much enjoy watching you guys build and test the newer offerings though!
Not guna lie, the BBX is one modern cat that really has got my interest..... especially after seeing Fils in action!
Interesting to hear about the
'gorilla snot' super jizz, and I am most surprised that you can actually feel the difference in the gearbox!
I have a couple of round pots of that, I think they came with my monster beetle kits..... Will definitely try it out now mate, cheers for the knowledge.
Looking forward to seeing this new project of yours in action bud, I bet that Gorilla jizz will be perfect for taking up the sandy bottom! 😬
😂 😅 🤣
😊
I know what you mean about boyhood dreams (most of mine were about Debbie Harry though! 🤣)
But yeah I'm with you on the BBX, by hook or by crook i will eventually get one!
Oh, you sod, wet meself reading your "taking it up the sandy bottom" 🤣😁👌👍
Rob did good getting this one for you! It is a fun and simple build but performs nicely and looks terrific! I agree whole heartedly in ditching the stock tires, they look great but are not good on any surface really! Kind of oversized drift tires! LOL! Great job explaining the build as you went and although I have built a few on this chassis I enjoyed watching along! take care mark and have a great weekend!
Thanks Addam, the weekend is going well thanks, hope you're doing well too! You know how cool this buggy is and it's gonna be a smashing little runner I hope! Haha 😄 oversized drift tyres!!!🤣 Glad you enjoyed the video even knowing the chassis! Must appreciated my friend!
Very well and deeply explained! Ciao
Many thanks! That's very kind of you to say, my friend! Ciao! 😎🙏👍
Great build And tips mate 👍
Thanks Mark, always appreciated! 😎👌👍
Great vid looks to be a decent chassis can imagine it would be good on sand 😎👍
Thanks Chris, yep it's a cool chassis alright, I've run one on the beach and you're right, it's great fun! Cheers mate! 😎👊👍
Always fancied this kit Mark ,but strangely put off just by the look of the chassis, but after watching your video I actually understand why it looks the way it does,I've realised it is quite a clever chassis tbh, definitely want one now lol,I'm going to sound like a thicko now but I've never thought of putting AW grease on with a brush 🙈,so thanks for the tip.Cant wait to see the body done and a little run around,great video mate very informative as usual 👌👍
Hi Carl, yep this is a strange looking chassis, it's just like a boat! But yeah the design makes sense when you think about it 🤔. Haha well I got fed up of sticky fingers so started to use a brush to apply grease a couple of years ago 😅 Just need to decide on a colour for the body! Thanks mate, all the best from Mark 😎👍
She a beauty Mark, hope you love her long time! Something I found with my Racing Fighter (DT-03) is the energy transference from the front wishbones to the chassis and servo is super efficient (not in a good way). Every time I clip an obstacle or land awkwardly on the front, there's a good chance I'm replacing something.. been through 4+ servo savers, 2 shock towers and 3 chassis in a year at most.
Thanks, yes I hope I can love her long time too! Strange that you have so many front end breakages though. I have had a Racing Fighter for over 4 years and never broke anything. I did fit the front Carbon shock tower from the get-go though. It's running a 13.5T brushless setup, so it's not as if it's slow! All the best! 😎👊👍
@MarkBryanRC ok ok make a fella feel bad huh.. i know when someone's telling me I can't drive in a straight line hahaha.. im just messing, in my defense ive got 7700Kv (like 5T?) motor in it, running 2 and 3S, but my crashes are rarely flat out. Thanks for the vid as always ❤
@@CPB24421 7700kv is a 3.5t
6600kv is a 5t and I've got both of these in Lunchbox builds 👍
Oh no I wasn't pointing a finger! 🤣Thought it was strange, all those breakages, but a 7700kv motor explains a lot!!! 😁👌👍Thanks for watching and the great comments, fella!
😁🤩👌👍
G'day there Mark!, Great detailed build video mate👌, I really like this chassis, we have one but have never driven it. Nice touch with the hex screws. Hope it's out ripping soon Cobber.
Hope you are having a great week mare👍🦘🇦🇺
G'day there mate! You will have to dust off that buggy mate and get it ripping! Yeah those screws are a good addition to any Tamiya, pity they don't come as standard! The weather here is crappy and getting worse, not sure how much RCing will get done but we'll do what we can! Hope your week ahead is a good one Cobber, say hi to Ingrid! Cheers! 😎✌👊🤝👍
@@MarkBryanRC
Hope you get a bit more nice weather Cobber so you can go play a bit. Thanks mate😁Ingrid says hi Mark🙋♀️😊.
Hiya mate. Ah yes I'd forgotten what a nice kit this is. Nice and straight forward and the end result is great with the Blitzer tyres. One thing I'd have done is to use the brass ball connectors to mount the shocks. Less slop and easy to remove the shocks if you need to. I'm hoping that this chassis will be the basis for next years speed challenge. Yours is pretty much ready for the brushed contest! I'm sure you're doing a lovely job on the body shell too. My Aqroshot body got a bit beaten to death and now it's got an HPI Firestorm body but other than that it's still going strong. Anyway, hope you're having a smashing weekend. As it's past 5pm I've obviously got a lovely pint on the go. Cheers for now 😁🍺🍻
Hiya my mate! Thanks for the great comment as always. Oh yeah, I wanted to fit those ball connectors, good call! I need to get some but it will be the steel ones as those brass ones wear very quickly! And yep, this would be my choice for the next speed thingymajig! Haven't started the body yet, too wet and cold! Great to know your DT03 has stood the test of time. I've also got a little tipple on the go and a curry on the stove! Cheers bud, enjoy your weekend too! 😎👌👊👍
@@MarkBryanRC Ooh we have got curry too! Enjoy mate 😁🍛🍺🍺🍺
@@PeteWylieRC Yum Yum!!! Great minds think alike!! 🤩👊👍
Awesome video, I live the DT03 buggy my daughter built and might build another... would live a truck version, especially if a Blitzer body could be fitted...
Maybe I could get a Blitzer Beetle, and one of these, and swap the tires to give the road tires to the Beetle...
Thanks! Yep, the DT03 is an excellent entry level buggy for sure! I think the wheelbase is a little too long for the Blitzer body though. Cool idea! 😎👍
Now that's good thinking!! What a great project that would be! 😁👍
I built mine with Blitzer tires as well, the width is right for a Blitzer Beetle but i had to shorten the chassi by cutting a section out in the middle to make the wheelbase right. "Stitched" it back together with strong wire plus epoxy to seal and for strength.
Designed a custom servo bracket to hold it vertical, instead of at the stock angle, to make the my 5200mah battery fit.
Since the chassi was shortened the battery doesnt slide all the way to the bottom in the front of the tub so i had to design a custom battery hold down, it screws in to two of the holes on the front and clicks in place by hooking into two other screw holes, really secure.
Then it was just a matter of making up some custom body mounts and ive what looks very much like a Blitzer beetle from the outside.
Went this route because the kit came with the right rims and i wanted to have a go at the DT03, seemed like a good pick since its more modern than the Blitzer chassi, cheap replacements parts.
The shape of the chassi makes adding a dust cover really easy, just cut a 50cl soda bottle to fit and attached it with a couple of pads of velcro, i also taped over the servo access on the bottom to keep stuff/water from getting in there and possibly fouling the steering/servo.
Had a torque tuned motor in mine and on the first outing it burned out, like got hot enough to partially demagnetize, making it weak and it also started sounding bad, like its grinding on the inside, no idea how that happened, was just running on some gravel. Became my first brushless Tamiya. It can do little wheelies on asphalt with the street tires so i made a wheelie bar for it, not likely it will be necessary but wont hurt anything that its there.
I love the dt03 buggy, debating another one... I'd love to see a somehow shorter version for a Stadium Blitzer and/or Blitzer Beetle style release...
I'm hoping to test a couple Holmes Hobbies retro sport motors after winter, in place of Torque Tuned, Sport Tuned, and silver can motors....
@@isaiahfurrow7414 if you search for "Blitzed dt03" on google the details of my build should come up. There really isnt a lot to shortening the chassi, i picked a place where the width is as consistent as possible and not intersecting any screws, carefully marked and cut away 27mm, drilled holes for the 1.5mm steel wire id use to "suture" the chassi back together. There wasnt any flex after twisting the wires together, i used a method used for tying rebar, with good wire its really strong, i suspect the plastic of the chassi is more likely to tear out before the ties open, even before the application of epoxy, i left a bit of meat between the holes i drilled and the cut. I covered the sutures and joint with epoxy which ought to give some additional strength but mostly to prevent the ties rusting and making the bottom of the chassi solid/waterproof again.
Many thanks for sharing your modification info in such detail! I'm sure anyone reading this could use your instructions to make their own DT03 Blitzer! I've also had a couple of brushed motors burn out, and yes I think it's small bits of gravel embedding themselves in the internals of the motor! Brushless is a great upgrade, anyway! Cheers!
Looking fantastic Mark! These are awesome and with the BB tyres have an amazing stance! Mine is still yet to hit the beach! I have the BB tyres on it so no excuse its ready!
The DT-03 is a classic already!
What's your plan with the body my friend?
Cheers James.
Hi there James! Cheers my friend, yeah it sure does have a mean stance! It's a bit cold 🥶 for a trip to the beach mate, at least for me and the fact that it's 100 miles away! 😅 Still deliberating about the bodywork, any suggestions mate? Hope you're doing well, all the best! 😎🤝👍
@MarkBryanRC yeah its not been good here so much damn rain! I miss going for a spin man! l did mine all black buddy and looks great but seen a blue one the other day and it looked super cool too! I wonder how yellow would look?? Anyway take it easy my friend Cheers James 🍻
Nice video! Just asking if the Super Stock motor is really 13T, the Super Stock motor that I can get is 23T.
Thanks! Yes the Tamiya Super Stock motor is 23T, but it does spin up to 27,500 revs, a massive upgrade on the stock Mabuchi silver can that spins at about 14,000 revs (RPM)!!!! 😎👍
😎😎🙏🙏🙏🙏💪💪💪
Thank you! 🤗👊👍
