MJO, I know about the actual yaw that you are describing...why don't you read my posts thoroughly next time. I am experiencing VIOLENT yaw effects within operational speed at the proper altitude.

I have waited long enough for a response from Captain Sim..both in this forum and via email. Even if I turn down the realism the plane is impossible to trim without it constantly climbing up/down. I contacted my credit card company and they are crediting me with a refund. Goodbye.
