APAS 5 brings 'Nifty Mode' and opens up a massively improved mode for Bypass obstacle avoidance. Not only does it calm things down, it makes a huge difference to flying through mulitple obstacles. I think you can see, genuinely impressed....
I imagine it's fairly safe if you take it steady. But probably risky at full speed, depending on how difficult the obstacles are.
I checked the manual, it seems the M3P only allows Nifty with goggles.
