No dead zone, unlike the Pro Flight (non Cessna) which showed 15 ° of dead zone to the left and I had to return. The wheel rotates 90 ° in both directions (45 ° for the other version) Round jack to connect additional controllers and USB for 3 trimmer, pedal and other equipment. Note, only one PC USB enough to power the entire yoke levers + + + trimmer pedals. No need USB hub so even if an external power supply input is provided.
