I'll try to answer both of these Posts

Hi Bigplumbs,
From your post it appears that you've had similar experiences with the quirks of the 2.4 tech , which is exactly what bothers me about the technology.
How is it acceptable to us that the odd bind can fail initially on swiching on ? What are the chances that this cant happen in the air ?
Ive had a situation in one of my jets again many flights old where I took off with a perfect bind and landed with LEDs on 3 receivers blinking LED on only one external receiver remained solid .
Yet on the next flight receiver location unchanged, all LEDs were solid and datalogger showed good values - I accepted it then as a 2.4 quirk !
This is exactly what bothers me - there is NEVER any clue why and what is happening
Considering the damage a jet can do how is it acceptable that we use control systems that can be described as a "Best of Luck" thing -
While it works its great ! But when it fails we dont know why ..... ?

First if your lights are blinking you did not lose signal,
you lost power. I'm betting that your RX and one of the satellites came in the same package and thus have the "NEW" fast reconnect software. The one that wasn't blinking did not have the fast connect software. Anytime you have blinking lights it tells you that your RX dipped below the low voltage threshold. This means you need to check for binding or beef up your power supply to the RX. JR/Spektrum will upgrade the one non blinking RX to the new software for free. Just send it in.
Not a Quirk......its working as it is designed.

I have to see I dont have a data logger and dont tend to check if the lights are blinking on landing. I work in the principal that if all went well on the flight and this has happened many times all is well. I ahve never experienced an issue of loss of bind after the system has bound.
I am also of the view that on those times the system doesnt bind it will actually bind if you leave it long enough. I think however we just get inpatient.
The issues I had were in my opinion very small indeed and have never caused problems.
If you have the quick connect software in your receivers the blinking will be showing some sort of loss of signal but because the reconnect is so quick you will not have noticed it. Not a problem to me if the plane carried on flying and you did not notice it in the air.
One of my friends is constantly wanting to plug his data logger into my receivers when I land after flights that were fine and I never let him. I dont see the point all it will do id potentially worry me as quite frankly I wouldn't understand the numbers anyway.
If it aint broke dont fix it I say.
I would agree that because I have had only good experiences of 2.4 I am confident with it. I fully understand your loss of confidence however because of your sad loss.
I assume you have had the rest of your gear checked out or even the module itsself.

While I understand your desire to not use the logger, it is very useful. The values are simple.
First value is the voltage currently going to the RX
Second/Third numbers are the 2 main Ant on the main RX. Any number here is a fade
Next number is a satellite and again fades
Next number is another satellite and again fades
Fade is the when all 3 RX's fade at the same time
Hold is when you have 50 of all 3 RX's fading in a row
So simply things to do.
1. Keep individual RX's below 50
2. Keep the Fade below 50 ( for example: If the value was 25 it means that 25 times all RX's faded at the same time. It does not mean that they did it 25 times in a row. By keeping that number below 50 you pretty much guarantee that you will never have a hold because it takes 50 in a row to cause a hold, so if you never reach 50 your golden. If you did happen to reach 50 then you are still beating the odds that all of them happened at the same time).
Now to explain Fades. Fade is similar to your computer. When you are on the internet and download a picture the computer sends and receives packets of data. It then reassembles them on the computer mainframe to show the picture. Its pretty much the same thing with your 2.4 radios. They send packets of info to the RX. When you miss a few it doesn't really hurt as the update rate is quite fast. You can't think of your 2.4 system in simple terms. When you hit left it doesn't just send a left command, it most likely sends about 30 small commands that equal left. This is why losing just a few is not a big deal.
As for checking with a logger after every flight? I don't do that but I do typically check at least once per day and always at a new field. I have found that in my Giant Scale gas planes that some fields I had to move the orientation of an antenna to get the low numbers. Then I get back home and I had to move it back to where it was originally to get low numbers. I for one think its a great device. For me its like checking the voltage in your batteries. You don't have to do it, but its good piece of mind
