Juls’s DB01 vs DB02 dual build thread

Recommended Posts

DB01RR steps 7-18

next up on the DB01RR we build the slipper clutch and centre drives. The included slipper on the 01RR is a standard variation, there is a optional slipper clutch that separately clutches the front and rear drive but I’ve decided since I’m not racing it’s a luxury I probably don’t need.

slipper assembled, quite a nice bit of kit.

installed in the motor mount.

At this point I’ve fitted 51278 DB01 concentric belt adjusters. Ultimately they don’t tension the belt, they stop the belt expanding over the drive pulleys. Need them? Well they are blue bits....!

next up we fit up the motor. Interestingly the chassis has a slot so you can bolt on the motor.  On another note, the gearing between db01/DB02 is very close with the supplied spur. Meaning the same pinion gear in either car is near enough to being the same gearing.

once the motor is sorted the centre gear cover is fitted. This holds the centre of the drivetrain in.

Next up the steering is assembled. I managed to find 54149 allot steering set. Unfortunately I was not able to find the trf501x alloy cross member for the steering assembly.

The Db01rr comes standard with CVD’s front and rear.

now it’s time to build up the suspension, the whole lot is pretty much identical on the DB02.

The 01RR comes with all the nice suspension mounts as stock.

The front hub is shared with the DB buggy’s and the XV01.

now we are done up to the stage of the db02. 

Next up we will fit up and compare the 2 types of trf dampers.

with both kits up to roughly the same level I decided to weigh them, interestingly they are within a few grams of each other at this stage. Close enough to call identical.

Did you finish these builds, are there any more pictures to show rest of builds? I'm  interested to see, especially the DB02 because I've got one on the way, I've brought it from someone selling on ebay. Ty^^

The cars are both sitting at that stage with no progression, I do intend to finish both of them hopefully before Xmas. 

Doing the buggy damper thread kinda stopped the progression, since then life got in the way. 

In the meantime I ordered big bore shocks for the DB02, I also ordered carbon damper towers so I can use the alloy camber link mount I have. 

Hopefully I’ll get back to these shortly.

Yes, I'm hoping to do the same with hop up parts. Where are you getting the big bore shocks from? I've seen the aeration shocks, i dont know how good they are compared to the big bore ones.

I think i got my big bores from Rcmart or Rcjaz can't remember.

The standard aeration are pretty good, the big bores are nicer though, and alot more money.

My buggy damper thread has the full breakdown

How did the DB02 build end up? I just found this thread as I’ve recently acquired a DB02 and am trying to learn as much as I can. It’s great to see the info you’ve shared! Great write up!! Thank you for that!

Yes, I found this build thread to be very well done and exceptionally interesting. My DB-01 build is completely stalled while I try to find a RRR chassis and some carbon reinforced bits, and I'll add the gear diffs if any show up. I've got tons of hop-ups but no chassis!

the DB02 is this far, I'm a bit stalled, life got busy, and lost my mojo for them for the time being.

Hello

Sorry for necroing this thread.

To Thread starter, is there any update with your build, especially with the DB02, im planning to get either DB01 or DB02 for my next build.

I kinda prefer shaft driven compares to belt, but most of comment here (in this forum) says that DB2 is having lots of problems, so i wonder about your experience having/running it.

Maybe anyone else having experience with running DB02 kit? Please share it.

Thank you for your replies

Hi

I'm new to this forum and I just find this thread about Tamiya DB02 from google. It's great to see the professional build of DB02 step-by-step, as I'm new to 1/10 RC car (but I do build drone / quadcopter and fly on my own).

I'm using the DB02 for my own research project. I use it to be the platform to build an autonomous driving car in 1/10 scale. The DB02 is my first RC car and I got it from donation by chance. It was left in someone's garage for dust and some parts were not complete and were missing. I spent some dollars to buy the carbon-reinforced parts and (nearly all) the hop-up options from Tamiya.

You may ask: Why using 1/10 RC car for autonomous research? It's because it is ackermann steering and is very similar to the real car. Plus it has ESC to control speed and servo for steering, both can be controlled by PWM signal generated by a computer onboard.

My DB02 is pretty much the same as Juls. But I'm using the Hobbywing's 13.5T sensored brushless motor and I use VESC instead. The VESC is connected to the on-board Jetson Nano computer through UART. The Jetson Nano has its separate LiPo power and can run ROS with LiDAR sensor for navigation and path planning. The driving command (steering and throttle) can be sent from the Jetson to the VESC and the servo through UART and GPIO. At the same time, the car can be driven using a standard RC radio controller. I use Polulu's RC Mux for multiplexing RC driving command from receiver and that from the computer (or even the computer joystick) to control the car to drive. I'm still working on the project and programming part. The onboard computer will be upgraded to a more advanced Jetson TX2 or Xavier NX. Feel free to comment and give your feedback to me as my DB02 may not be optimal for such heavy loading.

Perhaps I should start a new thread about my RC car project. But I've seen some reviews about DB02 and it's a legendary RC car from Tamiya. So my 2 cents here!
