RE-Xtreme RC DRB-REW Prototype #001 - DEBUT and play!


Setup nearly complete. FD3s Installed.


RE-Xtreme RC DRB-REW Conversion is ready for it's first live test. result--- AWESOME!



A last minute switch failure saw me swap the Airia from the DP-RWD into he DRB.


DP wipers are awesome items. All you need really.


First lap was good, second was better and only tuning can improve from this point.

I already love the way the chassis works. the ability to place the battery directly over the rear wheels is spot on with a shorty pack.

I tried many locations including a long full size battery all which gave excellent results.


Performance is already more predictable than of my previous DP Weight Shift Setup.


New Speed-Line setups are requiring a bit more camber to get the rear side bite happening.


But the DRB-REW is already spon on. Massive front steering angle is very very beneficial for CR-1 compliance.


With the level already high at GCRC,


We are all pushing ourselves to get consistency and improve more and more.

Good days ahead.

RE-Xtreme RC DRB-REW Prototype #001 - Wired


Wiring in... first laps around the kitchen tile are of course great.



I decided to ditch the massivly oversized Sanwa Super Vortex Plus D in favour of my trusty Accuvance setups. the small size means I had many more mounting options.


I have kept everything pretty tight. I may need small weights on the pulley side just to balance the rear slightly for equal roll.


Now... I am still finding the right setups for the M12s and Twin Servo Arrangement. But I'm making progress.

I haven't had as much time as I'd normally have for test and setup. But in a couple of weeks the final spec will be ready and I'll be taking pre-orders from that time.

I already have Pre-Production Prototype #002 design well underway having solved the minor issues so far.



RE-Xtreme RC DRB-REW Prototype #001 - Inboard Twin


Getting closer to debut.



Servo moved to inboard location.


ESC will be mounted rear right


Free battery location will allow for perfect balance.


fore, mid and aft of the rear axle.

RE-Xtreme RC DRB-REW Prototype #001 - Twin Config


Starting to install my test setup. Specifically designed for Twin Servo.


Setting up the front end without the central ackerman control bar or turnbuckle is less restrictive for setup with the M12S or Futaba 4PX in their dedicated twin model modes.

Resistance is also much lower with lower torque required for steering movement.

Steering servo can be mounted further inward by reversing the servo mount. with perfect fitment for low profile servo. But as I will be mounting the ESC between the servos, I am keeping them in the relatively normal locations widely spaced for weight shift.


Determining the exact height of the battery tray and getting the battery plate lined up for flush mounting.

Production model will include some slightly different details. 

You will notice the small decoration pieces on top of the stabiliser mount. Similar design for those without this item to add rigidity. I use the one the front without the stabi mount for rigidity.

Ample ground clearance and shock travel with low shock tower for weight shift.

Drift Package Diffuser mount also available fro common RWD ReAR battery setups.

Drift Package TypeC suspension positions and lower holes for 55~60mm shock and upper holes for 60~65mm


Battery mount available through bulkhead for position right above the rear wheels. Strap mounting is simple but effective. Black bands to be sourced.


Due to the reverse location of the motor, I'm running this belt conversion. Sakura Pulley is sightly modified for fitment. MSt 11T is sleeved for accuracy. This will be replaced by a 9T shortly.

Rear pulley is 13-40 using the standard size front belt. I will also be using a custom 9T here with the rer DRB tensioner.

it's all coming together.

Just need to fire up the ESC after changing the wire length... then it's test time.






RE-Xtreme RC DRB-REW Prototype #001


RE-Xtreme RC is proud to display the DRB-REW Prototype #001 in it's raw unfinished form.


The full carbon set is now a hands on experience.


From design to reality is a great experience.



Every measurement of every piece is accurate. 


Support for a whole host of different options.

4 different steering positions are just the start. 3 Different servo configurations, Many battery locations.


To start the build I had to choose a colour. Yes... Blue it is.


So the deconstruction of the blue Overdose DRB began and choices for original config were made.


Config No1 is as shown.

DRB V2 Front. Drift Package RWD Long Wiper.

Slim Hyper Drive brace, Team Suzuki Rear end and BD7 Ball Diff


There are a lot of overly complicated designs out there is RWD land. I've gone for simple to start with.

I am still finalising motor belt pulleys to replace the spur and spacers for the battery mount screw lengths and more but I am already super excited where this is going. 

NOTE: pulley on top of the OD motor mount will be removed as not required


The front is super optional. The upper deck can support the DP positions shown here with a lateral servo. Just ahead of those are the GRK slide rack positions.

There are 2 positions for the normal DRB wiper set in carbon replacing the alloy mount point. 

From the pictures above you will also notice 3 sets of steering wipers that I am evaluating to accompany those options.


But already the DP long wipers seem more than adequate. For someone who has already upgraded to the narrow scrub front end, this is an easy change.


Narrow chassis allows for a LOT of body roll. Rear tower has positions for 5mm longer shock or using a longer ball end to raise the length and regain stroke. All bulkheads have been raised 5mm in these images. 


This works with the cutout in the rear shock tower to allow for a flexible battery position.
Large cutout for rear spool also allows for a larger spool pulley to slow the rear wheel speed.

I will be running 9-40 ball diff and testing 9-40~45 rear solid axles in testing.

I will also be running 11-41~45 Motor belt pulleys to cater for the rear motor position.


Shorty pack or course allows for the most variations.

This is my current fave position.

There are soo many places to put the battery I stopped before I took too many photos.  


Most will mount the battery here. Only angled because of current temporary pulley. But the rear shock tower cutout allows for a low position.

Simple OEM DRB rubber straps will hold the battery no issues.


As you can see, I've incorporated the optional DP suspension positions and the rear diffuser location.

Twin servo and other positions are all ready.

I am still deciding a lot of what the first setup will be. But the electrics will be installed soon.

M12S , Sanwa Super Votex Plus D and Twin SRG BLX, Etc Etc....

A slow process but the results will not be bad. I can already see the hours of thinking about items paying off.

It literally took 1 hour to convery my other chassis to this position with everything bolting in perfectly.

Stay tuned for final config and first tests.


RE-Constructing the Samurai.


Starting point...


Finishing point... A little build that took a beautiful afternoon. 



With beautiful weather, I wasn't going to build this machine in the garage.... A balcony build for me...


Yes... Overdose parts a plenty.

Full SSG Carbon Graphite chassis and Shock Towers, Motor Mount with custom 3mm spacers for large pulleys. Steering and turnbuckles, Servo Saver and Antenna Post.


I can almost build a DRb in my sleep these days. But you always forget the sequence for a couple of things.


But a DRB build always starts here. the static parts form the base. 


Then you keep going until you start to get the belts flapping around too much.


Eventually you get the front joined to the rear with the upper deck keeping the chassis plate from flexing. 


Twill carbon on the Overdose parts can look a bit dull sometimes, but other times its just a nice thing.
Here we see Overdose, Kazama.


onward we press, Black grease on ball joints, oil on bearings... clean and pretty. V2 Front end with Wrap up next items also in place.


Ahhh, A roller. Finally. Belts tensioned. Shocks positioned.


A few pictures before the body mounts were added. Team bomber front support completes the carbon set perfectly. Customised SSG Hyper Drive Bridge adds strength to the weakpoint of the DRB. 


Red. Blue and Silver Overdose triplets.


So the end result reminds me how awesome the DRB can be.

It's a good thing I take these pictures because I can see a couple of screws still to be added.  


It's time to admire... While the prices of WELD Overdose Brand items have increased recently. The upgrades were never a cheap option.With only a single production run of most Japanese brand "Tuning" parts, you have to be lucky to pull these together.

This machine has been with me a while... Starting as a DIB-R then DIB275, then DRB HT, then DRB OD, then HIGH CS DRB as it currently sits.   Final spec is still around CS 3.2:1  F40-9-18-27R 

Unused Kazama FXR wheel kept for that shelf queen imagery.  

It's definitely seen some action... Good enough for the shelf or for the street.
