The less impressive teachers start their talk with a "I am not an expert" statement which in my opinion is lame. Get up, speak with authority and present what you know in your way. If an error is made, or someone identifies a Better way, acknowledge it and move on. If you make a big deal about it, it just gets awkward and painful. So move on! It gets easier with experience. Start with smaller groups, your friends, or your favorite employees so there is no pressure.

In the last training section I ran I hijacked 7 of my employees to sit through the talk. For me this is a no pressure scenario and nothing to lose. It went well, and when I moved to a larger possibly hostile audience I knew what to expect... As my employees were already brutally honest and I survived.

Also, if you are wrong, better to learn it now (that's why you learn so much faster as the teacher) than complete life and never know! When I'm wrong I take that as a positive thing, the case where I probably learned more than the student did.
