Hi BobZ,

Thanks for the heads up. During my inspection of the rx today I did notce that the horizontal (batt) plug seemed loose. The thing is though I am using the two channels on the end of the Power Expander (“Chan A” and “Chan H”) that have power connections to the receiver in addition to the signal connections. This fact along with the fact that I am using redundant batts and switches through a SuperReg into the Power Expander seems to make a power interuption unlikely. I dunno. I carefully rewired everything, and now the P E and the AR7000 Rx is out and away from all other power, ignition, and servo cords (except where it attaches to the P E) I will range check, ground test engine off/on, do a thorough series of taxi tests and try it again.

P.S. I've been following your posts over on the re: TOC1 Yak thread for about a year. That thread was the inspiration to buy the (now SD Models) Yak 54 in which I am having these Spektrum issues.

P.P.S. Good pics on the Cirkus Throwdown in LV too :-)

Best,

Dave
