Since when does simpleplanes have torque characteristics on the aircraft props? I knew only the heli props had that after 1.8. I was making a prop plane replica with 2 engines and didnt realise I hadnt set them to counter rotate and my plane kept yawing unexpectedly at takeoff. The torque thing didnt come to my mind at first, cause I knew the props had no torque so I zero dragged and collision disabled everything, still kept doing the same thing. Then I changed it to counter rotate as a last try and it worked. More than 2 years I have been playing this game and worked with props on majority of my time and I didnt know about this.
