I agree with rebuilding a new plane was rather extreme on the builders part. But, as most of you stated, just replace the parts, which is what we're going to do. I spoke with the builder yesterday, and he's sending new batteries, switches, regs. So, all is good. As I said, it's great to have someone admit to their mistake, and be willing to rectify it. Thanks for the input everyone. I'll keep you posted on the maiden flight. Thanks, John
