I had a try of the Terrain Hopper https://www.terrainhopper.com
Which has 4 independent motors.
Set me thinking,
I've googled controllers and can only find 3 channel...... Can you get 4? Cant see 2x2 working....
I assume it must use brushless motors with hall sensor to allow relative reduction in motor speed when turning since it doesn't use a differential.
Could anyone enlighten me?
Many thanks.
