Hy,
looks like there is a hardware bug round the RTC Battery and the charger of the flight battery

the RTC battery is a CR1220 (its under the NiMH flight battery holder)
if its new, it should be about 3,1 to 3,2V, should be changed if lower as 2.9V

And there must be a 100uF / ??V
it should be changed to 470uF /??V

Were to find the 100uF at the PCB-Board?
is it possible to change it self (no SMD?)

Hy

have replaced the orignal Elko 100uF/63V with a 470uF/25V at the same Place, no problem.
Cut the wires of the original direct at the Elko, sold on there the new one

RTC Battery CR1220 had 3,08V so I did't change it
