The newer FW will only show capacity and current data on Hobbywing ESC's 80A and above.

The smaller versions with 25, 40 and 60A are missing this feature! See Manual

Is this included in latest firmwares? I get the capacity on the ESC screen, but on on Flight Capacity, is the special firmware still needed? My version is the latest - updated this weekend. The radio is DX5e.

Hello,

no, you will need unofficial 2.4.4 which can be downloaded in on the forum:

Great, it works.

One more question - I had to configure the "I-Motor Shunt" to 143% for the reading to be correct (for both firmwares). I did the calibation while having heli on the bench, with blades dismounted, so no big load (it can run ~20 mins like that). Is this number - 143% - going to work well for real flight conditions or will I need to recalibrate?

Just curious if I can rely on capacity for the first flight.

No, it will not work.

Capacity measurement with no load (even with blades on) will be very off from real flight since Current measurement is very imprecise.
Only in flight and higher currents the precision is quite good.

Oh.. then it's going to be a careful flightthen.. I actually wondered if Spirit gets mAh from ESC or only Amps and calculates mAh on it's own. I guess the latter - then right, the Amps is jumping like crazy all the time during tests without blades.
