Product Description (And More Tabs)

An off-road buggy as an alternative model for the 4×4 X-treme Off-Roader set.





This is an alternative model for the set 42099. It’s an off-road buggy type of vehicle, i call it “Sand Runner”.

Physical characteristics:
39cm / 49 studs
Width: 31cm / 39 studs
Heigth: 18cm / 22 studs
Weight: 1,3Kg (with batteries)
– Independent suspension on all wheels
– Remote-controlled steering
– Remote-controlled drive on the rear wheels through a differential: RWD

Miscelanious aspects:
– The final gear ratio from the XL motors into the rear wheels is 1,62:1 it’s a bit on the fast side but can’t take on big slopes or very rough terrain.
– The front axle ground clearance are 4,5 studs, and 6 studs on the rear axle.
– The batteries can be easily swapped from below, only two liftarms need to be removed.
– The green button to turn on the hub is easily accessible through the driver’s cabin.

Making a video for this MOC was more difficult than i antecipated: since my current smartphone was being used to control it, i had to use an older smartphone for the recording. Check some real pictures below and the video at the bottom of the page.
