Can someone please help me? I have a single engine plane,when it's sitting at idle on the tarmat everything is fine. I have the parking brake set to ON,and give just a little power,as soon as i give just a small amount of power to the engine,the left wheel dings halfway down into the tarmat? (by the way,it's a taildigger). Also if i reload the aircraft,and this time do not set parking brakes,as soon as power is given the plane rotates (yaws) to the left,alot. I downloaded some tutorials,but do not fully understand the various settings to .air files ect..
