[kung foo man]

Found proper aircontrol function: https://github.com/ETrun/ETrun/blob/...g_pmove.c#L841

		static void PM_Aircontrol(pmove_t *pm, vec3_t wishdir, float wishspeed) {
    float zspeed, speed, dot, k;
    int   i;
    float smove;

    if (!pm_aircontrol) {
        return;
    }

    // accelerate
    smove = pm->cmd.rightmove;

    if ((smove > 0 || smove < 0) || (wishspeed == 0.0)) {
        return; // can't control movement if not moving forward or backward
    }

    zspeed              = pm->ps->velocity[2];
    pm->ps->velocity[2] = 0;
    speed               = VectorNormalize(pm->ps->velocity);

    dot = DotProduct(pm->ps->velocity, wishdir);
    k   = 32.0f * pm_aircontrol * dot * dot * pml.frametime;

    if (dot > 0) {
        // we can't change direction while slowing down
        for (i = 0; i < 2; ++i) {
            pm->ps->velocity[i] = pm->ps->velocity[i] * speed + wishdir[i] * k;
        }
        VectorNormalize(pm->ps->velocity);
    }

    for (i = 0; i < 2; ++i) {
        pm->ps->velocity[i] *= speed;
    }
    pm->ps->velocity[2] = zspeed;
} 
	

Feels way nicer now
