YD2-REX Shakedown @ Broz

 

Shakedown @ Broz. 


Or is it Akina-san. 

The track is looking great these days. 


But what about the YD2. Basically. The fist setting didn't have enough lock.  So an adjustment in front toe started to see improvement, then a front track change and more camber server mixed results. 


It's not far away from a solid setup. Very fast, very slidy, but it just needs to be a little more stable.  

Until next time... Let's think of how to improve.

YD2-REX Shakedown Ready

The YD2 is ready for a session. so the body is mounted up and the girls are in. 



Weigh balance by WW ladies. The chassis is tested on the house tiles and seems very forgiving. 



Added some custom canards and a few old stickers... maybe temporary.

Yokomo YD2 Evolution


YD2 - Evolution

The Yd2 is a chassis for rear wheel drive drift. With a gearbox that brings a lot of torque transfer and therefore traction.

Which one do you need? 

Initial Release saw the YD-2 and YD-2 Plus. 
Any Base Chassis like the Plastic YD2 includes plastic shocks and typically plastic everything. 
Suited to beginners for the flexible and strong parts rarely break. 

Any "Plus" Chassis usually has a few upgrades like a Graphite Chassis, the Alloy Big Bore Shocks and some Alloy shock towers and maybe some alloy Steering parts. 

As Yokomo produce a new set of custom parts resulting from user feedback, typically a month later a full chassis update will be released also with those parts. 

The original YD2 with low center of gravity was good for asphalt and high grip circuits. Like Yokomo's Yatabe Arena. This model continued to be evolved along the "E" series. 

Soon after release adoption was not great. The popular P-Tile circuits in Japan really were targeting weight shift chassis layouts, so the S series was developed around different battery layouts, and different high motor layouts effectively flipping the gearbox upside down. Ultimate performance on these circuits evolved through the SX and eventually the SX Version III full option is the highest spec available for low grip circuits.     

Later again the E-Series drivers wanted more traction and many users were turning the motor mount around to hang the motor behind the rear wheels. 
This resulted in the R conversion kit and later the R Plus. This would culminate in the RX favoured by high grip circuit users and this incorporates a more direct 3 gear gearbox. 

The Z takes the newer elements and revises the base model into a flexible motor layout design with a effective steering catering for a midway solution. Will we see a Z plus or ZX? Yes We just got one. 2/2022

Then basic evolution was 

S - Small track, High Motor Mount
E - Revised Base
R - Rear Motor mount 3 gear gearbox
Z - Revised Base 

Over time the X designation basically added to the Plus and then over more time we see Type II and III added

Version II and III started to see the introduction of more variable steering and slide rack with spot on ackerman and additional parts for more weight accuracy and rigidity.   

Right Now the best are based on the two types of Circuits. 

High Grip (asphalt) - YD2 RX Full Option
Low Grip (p-tile) - YD2 SXIII Full Option
Medium grip (Carpet) - Either are used.
