The new XB4 builds on a platform that has been winning races since 2013. Let's take a quick look at the recent updates to this championship-winning platform.

Xray XB4 2018 - 4WD Off Road Buggy

A Luxury Off-Road Racer

It's difficult to describe a 1/10th scale 4wd racing buggy as luxury, but XRAY seems to have managed that with their new XB4. This fresh redesign for 2018 already sports a number of championships including recent EOS Champion, European Champion, USA Champion and World Champion.

  • Redesigned chassis accommodates new lower motor mount to decrease the CG.
  • Lower motor mounts decrease the weight position of motor and central slipper clutch/diff, improving cornering speed and stability.
  • Redesigned lower composite central bulkhead fits the new lower aluminum motor mount.
  • Redesigned side guard allows motor to be positioned lower.
  • Improved shock absorber lower shims give more precise shock shaft movement.
  • Improved construction and production details on both front & rear differential crown gears results in quieter operation and increased reliability.

Kinda wondering what there is to improve over the previous model. I have noticed that stuff like chassis flex is suddenly a feature, not a disadvantage in modern cars, which I find odd.
