Overall view of my 1st caliber

24.08.2002 Add a dual battery system for more safety. I have no heli with only one battery. Here is why:

Problems	1 battery pack	2 packs + mechanic Switches	2 packs + Electronic switch
Additional cost of system	reference	+ 55â‚¬	+ 180â‚¬
Open circuit between battery and switch's pack	Failure	Redundant	Redundant
Open circuit in one of the pack	Failure	Redundant	Redundant
Battery short circuit in one pack	Failure	Failure	Redundant
One pack not fully charged	Failure	Redundant	Redundant
Switch failure (assumes between RX and backup sys)	Failure	Redundant	Failure
Battery connector from backup system to the receiver	Failure	Redundant	Failure
