Is it possible to lose radio signal and have the sats stay lit?
My 450 went in right after spool up going into a forward flip. 1/4 into the rotation failsafe kicked in, and so did self level. Strange feeling to see your heli come out of a flip on it's own. I'm glad I enabled self level in the Skookum for radio loss! This is the first time I actually experienced a purpose for this LOL.
Ofcourse there was nothing I could do to control the rate of descent. I was very luck that it ended up in tall grass with no damage

The flight log showed the warning of radio signal loss, the status led on the Skookum was flashing red and both sats stayed lit

I may start by replacing the wiring from the sats as I'm thinking it's either internal to the FBL unit or a problem between the sats and the FBL?
What do you think?

When doing a range check on my helis I go out until it drops off into failsafe. I did it yesterday with a new DX18 and new SK540, and when I brought the heli to the bench the software said signal loss but the sats were solid. I don't think satellites will blink unless there is a power loss, so that's why it looks like that.

On DSM2 sats blink to indicate power loss. This feature is not present when running DSMX.

Sats blinking do not indicate loss of signal.

Make sure that your satellite is clear of the frame. By accident, I had bent one of my antennae so that it was held inside the frame and not sticking out. I was doing some high altitude video and twice, the system shut down into fail-safe mode. I was able to still bring it in as normal and it was a hour later I discovered the reason. I have two satellites, one with the antennas 90 degrees to the frame and sticking out, and the second is 90 degrees to the horizon and sticking out past the frame at the rear. If you shadow the remotes with the carbon fibre frame, they will cause the 720 to entre fail-safe mode, so if you have a spot for a second (if you don't have two already), I would install the second to be on the safe side. Take care and glad to hear there was no damage.

I have 2 dsm2 sats 90 deg from each other and clear of the frame. 1 on the skid and 1 on the boom. I have been flying this setup for several years now and never had an issue before. After many crashes, the wiring just does not look great anymore. I'll replace that and maybe the sats as well. I just hope its not an issue with my TX...

It turned out to be a bad connection between the 2.4 module and the TX.
I ended up resoldering the connector inside the module, cleaned the pins on the tx and seems to be good to go for now.
I may consider hardwiring the module or buy a new transmitter if this happens again
