In regards to the whole battery redundancy and TX battery failing, How many times have you heard someone say ''my TX battery failed'' right after a crash? After being in the hobby for over 20 years, I have heard that a grand total of ZERO times.
I can easily remember the UK display team ghost squadron's Me 262 going in right after take-off at Jets over Pampa in Belgium. The model was brand new and it was the first time to be displayed at a jet event.
Plane took off, and after about 5 seconds it was all over.
Reading out both ecu's reveiled simultaneous signal loss.
One bad NiCad cell in the transmitter was the source of the problem.
