FY20 and FY21 faulty capacitors


We, at our FPV group in Spain, have just found that certain units of FY20 and FY21AP stabilizers mount ceramic capacitors that can lead to faults in operation. Simply bad quality ceramic capacitors.

This is not to be related with the yet reported C24, C25 and C26 problem.

The problem is that C5 or C6 could be faulty leading to high temperature in the PCB and high current consumption with the consequence of accelerometers malfunction.

The problem arises with the progressive degradation of the capacitors.

Now the question to Feyuz or Simon Yin:

Please could you inform us the nominal capacity of C5 and C6 capacitors in order to substitute them for good quality units?
