I might do that - email HobbyKing, and I could try it myself as well. I think that reference you gave me was for version 2, and that's what I have. But maybe it did change since the review.
Thanks again,
Russ

Russ,
You are correct on your understanding of "failsafe". It's what the rx does when the rx loses the signal (a.k.a. "emission beam") from the tx. Loss of rx power isn't an issue, as all of these tanks have a BEC (battery elimination circuit) that uses the main power supply to power the rx (versus a rx 4.8v power pack). So, if the rx loses power, so did the tank.
You might email HobbyKing to investigate the issue further, and share their answer with us. It is possible that they have upgraded or changed the rx in their 9x package since the review was done (reveiw date was 22 June, 2010), and the review was done a considerable time ago. You never know.
