Where we work with both B3 and B3+, I only have the worlds respect for them taking the worsed conditions, temps, altitudes imaginable and just operating day in and day out. Yes they default to typical Squirrel work mode if we try and confuse them or they got it right themselves. I will take a helicopter defaulting to flight anytime. We often find the ultimate rest switch, being the battery off then on again, resets the system and a problem is sorted out during the power up calibration sequence and if not even pilots can figure out which plug to loosen and clean and refit by going to the maintenance page. 99% of the time she operates like a dream again.
One of the Information Notices as well as a service Letter you will find on TIPI is the one from EC informing all that on a 350 no rotors turning is allowed without a rated pilot or qualified person behind the controls. Shout and I will provide the reference.
Signcutter, enjoy the B3+ as it can't be simpler!
