I'm trying to teach my 5yo to fly a Sidewinder - he has his own Commander and everything - and it's actually easy enough with launch & docking computers active...we're using a 360 controller, as he can get his hands round it, but I was hoping that having two plugged in as we do, that the second controller would work too, so it'd be like a dual control driving school car. However, the second controller isn't working once we start up...anyone got any ideas?
