TEST: WLtoys/XK K959

null

INTRODUCTION

XK (a new division of WLtoys) annouced recently the K959, a 1/12th 2WD brushed model. To make short, it’s a revival model of the L9x9‘s serie appeared two years ago using at 95% the same part elements (chassis, gearbox, motor, radio, etc…). It’s a good thing since the L959 was and still be a “cheap” and popular first entry model.

BOX CONTENT

null

+ 1 x WLtoys/WK K959 (with a 2S 1500mAh LiPo ending with T-dean connector )
+ 1 x Transmitter (using 4xAA batteries not included)
+ 1 x Charger using balancer plug
+ 1 x Pastic cross wrench
+ 1 x Instruction manual (English/Chinese)

OVERVIEW

Canopy

The orange “climber” canopy is pretty nice in a first glance highlighting shock absorber systems

null

null

Almost all elements are in plastic/nylon: chassis, steering arm, anti-roll cage, wheel, gear box elements, etc….
At least, with the parts of the pro L9x9 you can upgrade for allow gear pinion a spur.

Battery bay

null

Some free room is available to insert at least a longer model. Compare to the original L9x9, now a T-dean connector is prefered versus a JST one.

null

LiPo

As for the L9x9, a 2S 1500mAh lipo is provided. No discharge rate mention

null

Transmitter

The same radio as for the L9x9 serie is used (based on the nRF24L01 RF chip). A good and simple RTF model. Trimming are digital.. I would prefer pots. 4 x AA batteries to feed this radio

DISASSEMBLING

Front wheel uses 2 bronze bushing (5mmx9mmx3mm) instead of real ball-bearing. It’s a better option to replace them with shielded ball-bearings. You will need a total of 4×2 5mmx9mmx3mm ball bearings for the 4 wheels. For rear wheels, you need two 12mm hexagons

null

null

null

Unclipsthe two front clips and you can remove the front canopy desk

null

null

Front shock absorber system

null

null

They are very soft… too soft and in practice, a lot of direct of contact with ground occurs. A bad point to protect the bottom part of the plastic chassis

The front bumper is for me too weak to absorbe a frontal shock. THis one is attaching the canopy …. so you will need probably to stock this part as spare

null

Removing the rear clips and you can access to main upper part of the car

null

null

The 3-1 box is the same than the L9x9 serie. Same radio protocol used. The FC box is filled with sillicone to be waterproof. A tiny free port can be used for LEDs power source

null

The rear shock absorber system is completly undersized for the weight of the rear part. A simple fall of 6cm let the chassis in contact with the ground

null

null

Now the 540 type brushed motor have now an extra cap to avoind dust intrusion, a good point.

null

The steering system

FIRST USAGE

CONCLUSIONS

This K959 keeps all the good offroad capacities/properties of the L9X9 series being able to handle well ground, medium grass zones. It’s fast car !!! and very fun for a first offroad car. In practice, it’s a durable car too. Of course, it’s far to be a perfect model: plastic gear/pinion elements, weak front bumper, too soft shock absorbers among them. The price around 110 USD is a little too much IMHO, I remember the L959 was sold around 80USD at beginning (now it’s 93 USD)

UNBOXING

PROS

+ Beautiful design
+ Good first RTF model
+ Fast (up to 40km/h)

CONS

– Too soft shock absorbers, especially rear ones

This car have been courtesy provided by Banggood in order to make a fair and not biased review. I would like to thanks them for this attitude.
