WPL B36 with 260 motor and dual gearboxes

The stock 180 motor on my WPL B36 was a bit too week in rough terrain so I thought a 260 motor and gearbox for MN99 would solve the problem. It did not! A little more speed but even less torque than the 180. So I did an experiment by gearing it down. Added a gearbox for Subotech BG1522 in which I mounted a pinion with 3 millimeter shaft in stead of the motor. The 260 motor (frontmounted) with two gearboxes makes a dramatic change. It is really strong and conquers about everything, but it´s also extremely slow! This is a video about it.
It´s also the first test of my recently purchased Gopro Hero 7 White, that I think performs surprisingly good for its moderate price!
