Quote from the manual with the Spektrum module I bought for my JR 388:-

"A hold occurs when 45 contiguous frame losses occut. This takes about 1 second. If it occurs in flight it's important to re-evaluate the system, moving antennas to different locations and/or checking to be sure transmitter and receivers are all working correctly."

Not sure if this helps but it's what Spektrum say. Don't think this is in the DX7 manual as it relates to the flight log but the AR7000 should behave the same way. Note it claims one second which is a lot quicker than the outage smo0 reported.

G'day Alan,

Got plenty of battery in the Edge (which I have already been flying with my JR 388 Tx). 2 X 1700 Lipos with an Emcotec handling the switching and feeding the servos. Had to change Tx as the 388 dropped its memory on Friday (8 years old) and I had to order another board mount battery.

BTW, whats on in Warialda? Didn't hear anything about it yet. I'm doing an instructor course at Cootamundra on 3/4 Nov.

Cheers


Terry
