I was just wondering why do you have resistor with one end floating near gate of MOSFETs?

it's only a mistake ...
it's for reducing heat by dividing the power in same resistors.
all these floating wires has to be connected to make the 4.7 ohms resistors be in parallel and dissipe more heat.
regards.
