Default V52 bec power up delay?

Just bought a new tribunus and updated to v52. Noticed that when plugging in lipo, there is a few second delay before fbl powers up. Is this a feature of the new firmware? Just want to make sure there's not a problem with my new esc.

Looks like its a feature of v52.

2nd entry down.

- for 14S ESC increased measurement precision on phases (better starting, better sync)
- Added additional start up calibration (increased power on time)
- Added one more protection for maximum ESC temeperature (2s delay, 130 for mosfet, 110 for control)
- added event flag for sync loose (after 2s of sync error, power will be cut to 40A for14S and 12S, to 30A for 6S)
- added short circuit protection
- set default BEC voltage to 5V
- fixed bailout and restart mistake for Vbar mode
- added RPM output signal for all modes
- added writing instant error code to the log
- Added time for "uncolicited" telemetry mode.
- Changed maximum allowed current for 14S to 280A.

Hi,

I noticed this as well.
This is in my opinion a very nice feature. normally when you rebooted it due to a store procedure via vcontrol it did not but up correctly after that.
now it turns it self off for a few sec and then it comes back with correct initialisation.

Another thing i noticed is that my battery connectors doe not pull a spark!

Cheers,
