RE: Add Telemetry or Not?
I see Telemetry as a "Gee Wiz" feature also. I mean, sure it's nice to know if my battery is about to die, but I'm not going to take my eyes off the plane to check it!
Besides, where will it end? Will it tell me if I'm running low on fuel? Will it tell me if I have a piece of covering that is coming loose or a screw has fallen out?
Some things just have to be left to the risk factor. (IMHO)
Now I know that some people will come in a flame me by saying, "If there's something you can do to prevent a crash, you should do it!" Fine, if that's YOUR choice, have at it. Far be it from me to try to stop you.
But personally, I would much rather throw a plane in the air and have some fun than spend all my time worrying about how to prevent a crash.
