Ron,
I've been in touch with the Shulmans. There is no imperical evidence that the mirror caused the loss of control. I have done exhaustive research on the reflective/obstructive properties of various entities,and their effects on signal propagation/reception of 2.4g transmissions. The results are invariably inconclusive. The bottom line is that we are using 2 Rx's into a cockpit srs,which will pick the best reception,with antennas on both sides of the plate. If I'm taking a chance,it's definitely a measured one.
My response/question is,how many flite metal jets are flying around with no issue. Every expert I talk to brings the subject of metallic reflection/refraction. We need a real Jedi to tell us what's up. Truth is no one knows. Safe bet is don't do it. My buds spent serious time and money to make this for me. Thanks for caring. Happy Holidays.
Erik
