volt gauge indication
 

Mi hitec focus 4 volt gauge indicator never shows 100%. At fully charged battery I measure with my tester 11.1 volt ( 8 cells pack) and then gauge shows 90%. Normally when I go to the field ,after first flight ,the gauge goes down to 80 % very quick and stay this way. I feel a bit uncomfortable looking at the indicator in the 80 % position.

May be this is not a problem. Is it?

What do you think about it?

Somebody told me that there is a way to adjust the full scale setting in the gauge. ( I know this is not a solution at all , just curious about it )

Thanks in advance.

This is normal, dont concearn yourself with it. When the guage drops below 70% then you are getting low.
