- Team Yokomo YZ4 -
Debuted at the opening round of the EOS in Germany 2 weeks ago where it won in the hands of Lee Martin, the new YZ4 from Yokomo has been designed by Shin Adachi and is a big departure from the previous model. Featuring a dual belt design, replacing the previous shaft drive version, both belts drive a 2wd style 3 gear transmission at either end of the car. This allows the use of small gear driven differentials, the size of the diffs being the basis of the new car, but with small belt pulleys prone to slip this gearbox idea was developed. The result is a car that is easier to drive in the way the power is delivered .
The new configuration sees the motor centrally mounted under the top deck and allows for multiple battery mounting positions for adjusting the weight distribution in the car and can even accept saddle packs in both orientations. Developed on Astro and carpet, but set to work very well also on dirt, it sports an aluminium chassis with a 15 degree kick up with very little overhang so that it can clear jumps without catching at the front. The top deck has touring car inspired flex adjustment and apart from the uprights, c-hubs and shocks is a completely new car. Expect it to be released in November.
Designed by Shin Adachi the car features a totally new drivetrain layout with dual 2WD-style 3-gear transmissions on ether end which are coupled by dual drivebelts to replace the shaft drivetrain of the proven yet slightly ageing B-Max4 car. The setup allows to use very small gear differentials without having to worry skipping belts while the overall design also results in an easier to drive and less edgy car.
The mid motor buggy is based off of an aluminium main chassis plate with reduced overhang and it accepts a wide range of battery configurations including a transversally mounted shorty as well as saddle packs in both orientations. The top deck will allow for different chassis flex configurations as seen on electric touring cars. Different from the works cars the Yokomo team is running at the Worlds this week the standard kit will come with a range of composite parts such as front and rear shock towers, rear suspension mounts, and servo mounts. Also included in the kit are steel turnbuckles with the carbon fibre, aluminium and titanium option parts will becoming available in time for the release of the kit some time in November.
