I ordered two to use in my Vasa Fusion. I really like the feature to log servo force. I simply have no clue how much power the servo uses when flying. I only know we add servos capable of 40kg, but I never knew how much of that is really used.
I have a big 3.3meter Extra 300 flying on only 5 servos in total, it does well I must say.... it's laid out for 13 servos though....
