Everybody that's replied.....thanks for advice. FYI....I have since moved my battery pack away from the engine firewall due to the 'what if' factor. It's too nice a plane to take chances with 'what if' I have a problem. By the time I discover there is one, it may be too late. I've added some lead to the spinner cone and moved the battery back near the receiver which is how most of my planes are set up. Best wishes guys!
