Some questions about the thrust calculation

[Orca-bit]

if (tauz >= 0) { if (fx >= 0) { //forward thrust on the left thruster will be limiting factor max_fx = (MAX_FWD_THRUST - left_thrust) * 2; fx = std::min(max_fx,fx); }
hello, when the tauz is larger than zero, the left_thrust will be negative, so why is the max_fx larger than MAX_FWD_THRUST
