Yokomo YD-2 Build and Review

Well look at what I have here...

Its a Yokomo YD-2, given to me by Matt Vokes from DDRC to build and review. These have been around for a little while so same as always, building guide followed by conclusion. Read on..

The manual is in English, very clear images and instructions accompanied with a numbered bag system. Also in a kit are some crude tools but sufficient for the job

Bag 1 & 2 - Toe Blocks, Steering Set & Battery Posts


Standard hinge-pin toe blocks, each one is marked with it's length and there a 3 to choose from giving a few in-board toe adjustments to play with. I found the battery posts kept slipping in my hands but the little slit allowed me to hold them with a hobby knife. This new steering designs boasts increased tuning and grip via the Ackermann but no adjustable center link.

Bag 3 & 4 - Gear Diff Unit, Gear Box & Motor Plate


The main event. This gearbox has become renown for it's design and how it produces and maintains traction. A gear diff with a maintenance kit (and 10,000 weight oil!!) and 3 gears in the box give a drive ratio of 2.6:1. With the included 20T pinion and 84T spur (48p), this gives an overall FDR of 10.9:1.


Very heavy already even without the motor but it's sooo smooooth!!

Bag 5 - Servo Saver

It will be the decision on the owner whether or not to fit this saver or fit their own one, the servo mounts are fitted at this stage.

Bag 6 - Shock Towers & Front Bulkhead


Good quality shock towers and they're really thick! That's Yokomo quality plastic!


Bag 7 - Upper & Lower Suspension Arm


Standard Type-C suspension here in the usual Yokomo standard plastic. The ever popular Type-C upper arms given plenty of caster adjustments coupled with 4 setting holes give a whole load of tuning options... And NO friction!


Careful when tightening up the set screw for the lower arm length adjustment; the lower rod has a flat side and that it where the set screw needs to be.

Bag 8 & 9 - Steering Blocks, Hub Carriers and Rear Lower Arms


I was impressed with the steering blocks until I saw the hub carriers. The amount of tuning for roll that's available is incredible!


Bag 10 - Shocks & Springs


So these shocks were the nicest I've ever built! Even though these are plastic, everything went together so well and they feel so smooth. The springs also feel a little stiff to me but I've never run rear motor chassis' so as per instructions. The oils supplied were #200 and #300 but the manual indicates that #300 should be used in the fronts and #350 in the rear, so #200 will go in the front and the #300 in the rear.



Bag 11 - Front Bumper & Rear Diffuser



Standard setup here with the front bumper but loving the rear diffuser. 3 piece large or 1 piece small but either way, it sits beautifully on the tail of this chassis.


Bag 12 - Upper Deck & Battery Holders


Now the upper deck can be somewhat of a nuisance when fitting and changing electronics, especially if you're a neat freak like me. However, 4 screws to remove it and access is gained to the bottom deck. 2 sets of battery holders supplied; one for shortys and one for standard. The holders themselves just slip on. Perfect.

--------------------------------------------------------------------------------------------------------------------------

Conclusion:

This is by far one of the nicest chassis' I've ever built. Every piece has been designed and manufactured so well that it all goes together smooth like butter. And talking about smooth like butter, the gearbox. Oh the gearbox. It is a thing of beauty! 3 plastic gears and a metal pinion sat perfectly next to each other giving the smoothest drive I have ever come across. all surrounded by Yokomo quality plastic, this is one of the few chassis' that doesn't need new parts unless you break something!

(I unfortunately ran out of time so I couldn't wire it up but here's a link if you'd like one of your own)

I hope you enjoyed the review as much as I did building it. Thanks for reading and as always, keep drifting fun!
