Doug and RCSE, Browne didn't mention that the contact with the power lines occurred within approx. 150-200 ft. of parked cars and after witnessing over the years 4 events where sailplanes lit up the sky after hitting high voltage lines.this one was by far the most spectacular. The Ava hit

1. The power lines in question are on the west side of the road which runs along the west side of the field; the winds were from the east, so we were launching and landing west to east. 2. We did notify Austin Energy about the incident, and they sent someone out to inspect. They said that

It is entirely possible that the energy generated (EMI/RFI - from DC up into the GHz) by such an event could adversly affect RX's OR the TX's. The more likely reason the RX's have been compromised has more to do with circuitry that is already powered up. The additional energy may exceed the

I just ran a range check on a Hitec 555 receiver in my dlg Photon which was either inside or alongside my van Naturally, any Rx that was OFF at the time would not have been damaged. The concern is about the Rx's that were ON at the time. Frankly, I'm quite skeptical at the moment. I'm waiting

As previously mentioned, damage to devices that are not initially powered up should be fine. However the path of the extraneous noise (from the event) does not emanate equally, therefore a device which was near another which was adverely affected may also be fine. It is a hit-and-miss affair.

The receivers that would not work after the incident were not powered up when the incident occurred. Those people who were flying at the time have reported no radio problems.
