This is the Yokomo YZ-4 1/10 Scale Electric 4WD Buggy Kit. Designed with a radically different drivetrain than the previous B-MAX4 series of vehicles, the YZ-4 is a next level buggy incorporating years of winning heritage from the long line of Yokomo buggies.

Designed by Shin Adachi, and already claiming victories in the hands of factory team driver Lee Martin, the YZ-4 incorporates a dual-belt design connecting dual 3-gear transmission on each end of the vehicle. The design allows for the use of small and light gear differentials, as well as small diameter belt pulleys to help alleviate the frustrations of skipping belts.

The buggy also features a balanced chassis layout with a forward-mid motor placement, with a rearward battery placement. The aluminum chassis accepts many configurations of batteries, to suit all needs and weight bias concerns. 

Included with the kit is a carbon steering plate, carbon battery plate and a carbon fiber top deck - which allows different chassis flex configurations similar to touring cars. Other features include steel turnbuckles, big bore (YZ-2 spec) shocks and many aluminum parts.

Yokomo YZ-4 1/10 Electric 4WD Buggy Kit
Amazing car on high bite clay Just need to tweak my shock setup to get rid of some bounce when overshooting a jump, thing is fast, and has that killer belt drive sound. More stable and predictable then the D413 I am keeping as a backup, and can pushed harder in the corners without traction rolling. Took some really hard hits (overshooting a triple first pack out, and nothing broke, so durability (at least with my kit) is spot on. Probably not as strong as the D13, but the performance difference between the two and cheapness of Yokomo parts makes that a moot point.

Yokomo YZ-4 1/10 Electric 4WD Buggy Kit
After having success with the YZ2 I decided to get the YZ4. The parts fit and build quality were as expected. Only thing that I see for a spot for improvement is the addition of some aluminum parts like the YZ2 had added to the kit. This wheeler drives better than the other brand wheelers I have driven. The shocks are amazing making for a smooth driving buggy. Would recommend this buggy to anyone racing on turf.

Yokomo YZ-4 1/10 Electric 4WD Buggy Kit
Wanted to get into 13.5T wheeler class and saw this on sale for Black Friday. Kit was "supposedly" a hard build but was pretty standard. Its definitely a quality kit. My only complaint is around wire management. Due to the belts, spur gear etc....wire management is somewhat of a nightmare. I am concerned that something will shake loose and get caught up in the belts or the spur/pinion. Theres not a lot of real-estate to mount the electronics which is another downside. Outside of that, I am super pleased with the buggy and for $234 for the kit, it was a steal.

I personally would buy this again.
