Hyper Lemon was out to play... Anyone up for the battle challenge? The answer at GCRC is always... YES.

Hyper Lemon... Experience the squeeze!

I don't regret selling this body. Because every time I see it again, it gives me that rush, like it's just finished.

Still looks stunning slashing past. I have to be careful not to look too closely when I'm chasing though.

Overdose Chaser also in the hunt.

Quickly settling into a rhythm.

Gaps of less than a car width are about the norm. Constantly tight, all night.

RE-Xtreme has been feeling the evolution in RC recently, with rear wheel drive options really exhibiting some dynamic changes of late, the look and feel for my own chassis is getting towards the similar look and constant angle of the mid to high cs cars.

180sx FR-D and  Drift Master derived Weight Shift chassis  were working well.

I'm trying hard not to loose the style I enjoy with CS also. 

Seven's month not over yet!

Battle hungry.

Chase Down! Hachi V S13.

Chasing the CS cars with gaps this close requires some major concentration. 180sx is just stopping my loose rear fender from flapping around.

A few great laps with the Hyper Lemon too.

I love this shot of the 86! Showing off the exact style I want!  Powering through. When I'm off throttle, the splitter is on the ground. Such is the way the chassis behaves utilising the long suspension stroke.

Thanks to my photographer... keen to get that shot.

And this is one of them.

All that's missing is mountains of tyre smoke. But at GCRC, it's always a wet track look.

 Handbrake on! Out to the wall!

So as the second half of 2015 is underway, I am wanting to see how far I can push this chassis especially.  

It's definitely got a load of potential.

Aryn's Mistress... "Bianca"

When you spend nearly 2 months staring at catalogs, ordering and accumulating the components necessary to build an top shelf modern spec drift chassis, you can't help falling in love with it.

Her name is Bianca.
 

Arun's Hikotech Bianca is one of the new breed of RC Rear Drive Weight shift drift chassis.

 
All the weight where it should be. Just forward of the rear bulkhead, for a heap of traction and plenty of flexibilty for battery location.

The owner has chosen Sanwa Super Vortex-D ESC with inbuilt receiver and Accuvance Luxon BS Dual motor. All totally controllable from the Sanwa M12. The Gyro is notably not Sanwa however, preferring the feel of the MST V2 instead.

Spur cover is always a personal finishing touch. Tail Slider getting the honors. 

The Bianca chassis is a conversion for the Yokomo Drift Package, however this chassis was sourced from all new components. RC926 Drift Package towers add impact, complemented by Overdose suspension mounts and shock absorbers.

the Hikotech slide rack has a beautifully smooth feel and it matches well with Wrap up Next Suspension arms Both Upper and Lower

MST knuckles give all the lock you will ever need.

narrow Y arms give you plenty of space for componentry



Rear WUN arms also designed for traction and less geometry change.

Chassis plate has plenty of ajustability

Overdose shocks with OD shock oil provide a different feel to most other shocks out there.

KN Kinkaku is the main company behind the RC926 brand. An interesting use of the adjustable body mount looks good here. 

With the long battery currently mounted longitudinally in the chassis for now, performance is great straight of the setup bench.

More to come.

RE-Xtreme Drift Bible - Steering Scrub Radius

 
Let's have a look at the newer trends in upgrades... Why do we need narrow scrub radius steering knuckles?

Focus on the steering here... the rest of the chassis doesn't change. These items are for Full Counter 4WD Drift and/or RWD. The principle is the same.

Doesn't look to different to a stock SSG DRB actually, but what we are doing is aiming to reduce geometry changes and chassis movement through the steering range.

The old parts I'm replacing here are Overdose KPI knuckles. not a bad item, but the distance between the pivot points (ball end) and the shaft thread is about 16mm

Yokomo Option Knuckle 20mm lower & 20mm Upper

Overdose KPI 8 16mm lower, 19mm Upper


NEW Yokomo Narrow Scrub KPI 7degree 10mm Lower 14mm upper. (top picture)
NEW Yokomo Narrow Scrub KPI 0degree 10mm Lower 10mm upper.

Old style requires a pivot point closer to the chassis.
Note the lower arm extension.
Upper Pillow Ball is clearly visible.

For the same track width the Wheel offset is 5mm wider also.

So Pivot point to Axle is 19mm + offset 9mm. 


Note: These MST rims have been adjusted +9mm Offset with the rim face barely visible.
 

The narrow scrub items place the pivot point  further away from the chassis.
Note the larger lower extension arm.
Upper arm is covered by the wheel.

The CVD dogbone changes from 45.5 to 51mm

The wheel offset changes to 5mm and the face is easily visble.

Pivot point to Axle is 10mm + Offset 5 mm

Note: These MST rims have been adjusted +5mm Offset with the rim face clearly visible.

Compare the differences.

Top Chassis is Wide Scrub with the wheel illustrated by red lines on the bottom. 
Lower Chassis is narrow Scrub with the wheel illustrated by red lines above.

Narrow scrub has a reduced distance for and aft when the wheel turns. This is great for body clearance.
The Lift from castor also is reduced with this setting

And basically we gain more response with a faster action. The wheel doesn't move as far.

You can also see this in this picture.

So is it worth the extra money for a setup like this.

In RC, every mm is valuable. I have upgraded many parts on this DRB. When they all work together, the results are noticeable.

But having said that... I have 4 DRBs.
I still uses C-Hub with Overdose 8-8knucles on two and they perform very well.
Sure it may not be as sharp in response, but depending on the surface, sometimes twitchy and stable are contradictory for good performance.

Narrow Scrub radius may allow you to cut less from your wheel arches on the body and gain in style with aggressive castor and other settings. 

If you have already spent $2000 on your machine, why not another $100

For now the Yokomo DRB with Overdose and other tuned accessories is complete.

Seven's Day @ GCRC: Part #4 The FUN.

A little warning... This photo set ROCKS! Three....

TWO...

ONE...  ROCK ON!

Skulls and lace style bonnet on the slide.

70's vs 80's

Pan Speed on FIRE!

Copper beast!

SCION... maybe not. but cool none the less.

Running the wall means sometimes, someone is up the inside... 

But when three in row is lap after lap... smiles are common.

Mixing it up.

RWD Switch backs. sooooooo close.

SA22c... deep in Aussie history.

 FD3 Yess,

The bumper is gone for a reason... Run the wall!

Lurverly paint.

Very pretty.


Did you say tight? Tight and on lock.

Yes, I said TIGHT and ON LOCK

ON LOCK.

LOCK ON!.

Tandem practice coming.

Running up to the pack...

LEAN ON ME!!!

LEAN on the RWD... It's good fun... We all try to get a full lap on the door of this hachi... RWB hachi driver runs a line and speed that just begs for constant door scraping.

Lemon slice!

Seven's Day @ GCRC Gold Coast RC Raceway... Absolutely Awesome!
