TATRA T813 Kolos 8x8 - LEGO Technic MOC

I present you my take on LEGO Technic Tatra T813 KOLOS in Truck Trial version. I’ve built it for our LUG’s truck trial race last year. It’s 8 wheel drive with Tatra suspension, using 1x PF L motor for steering, 2 x PF XL motors for drive and 1x PF M motor for remote control of 2 speed gearbox (1st - 23,3:1; 2nd - 8,3:1). Gearbox is in priciple similar to Sariel’s Heavy Duty 2 speed gearbox from his book (The unofficial LEGO Technic builder’s guide). Basic steering design is similar to Tatra T813 by Madoca.
