Been aware of the battery-locking tab problem since buying the mini 3 pro (very thin... very lightweight plastic). Most people squeeze the two of 'em way too hard before withdrawing the battery.
I gently pull the battery body backwards before...
A few thoughts:
Obstacle avoidance - while it works reasonably well, you should NEVER depend on it to keep you out of trouble. It should be considered more as a backup
The mini series does not do terribly well in higher winds - I doubt you...
Wind will be a problem with the mini Fly with care in the wind. and yes you will see reduced Battery times in the wind but I don't think its a deal breaker for the mini at all it will handle some wind with ease.
You Don't need a Part 107 to fly...
