This time I tryed to make the lighetst big scale offroader possible. For that I used only one Xl motor and the lightweight rechargable LiPo battery box. I aimed at the weight of 800 grams and managed to do better. With panels the truck weighs 750 grams, which is 2x lighter than avenger. Because its so light, the gear ratio was decreased to 1:3, which makes this offroader one of the fastest built too. For maximum flex there is four link suspension on both axles, simillar to one from avenger. With the use of H frames I also managed to amke axles much smaller, lighter and sturdyer. Also there is lots more weight in front, which also helps to keep the truck stable when going uphill.

The rear axle is a bit anorexic, but its very strong!

The driveshaft is accelerated by XL motor which helps to reduce load on the u joints and torque twist.

Very high suspension flex thanks to 4 link setup and diagonal springs.

Like by most of my MOCs, there’s an LXF file:
