Climbing the hill by 3D sets

Nové kovové disky, nové pěnové výztuhy do kol, nové soft pláště, zpevňující kroužky do disků, kde je šplhací limit 3D Setsu?

Zase moc pěkný, jaký motor je v tom modrém Jeepu (rancher)? Nebo celkově jaká elekronika?

I wonder why it struggled to make it up that dirt hill. Is it too light?

[@ferosofranek8817]

In my opinion it is driven too fast. Surface is very soft/weak and not capable of transfer big force from wheel. Solution is wheel with bigger surface contact (or more wheels) or driving it slower. But there is a catch - they use standard sensorless BLDC motors with sensorless ESC and they don't work in slow speeds (under 10% of nominal speed) or perform poorly.
