Since Steve has no idea what the qualifications are of any body on RCU are to discuss this subject, I thought it would be a good idea for him to get in touch with the manufacturer of his RC equipment and get the answer from some body who really knows. This is a very important subject and could lead to an in flight failure if the wrong advice is given and followed by Steve. So Steve, do us all a favor and send out that email. Please post the response you get. Dan.
