Responsiveness

[regdawg]

I know this isn't a Phantom but I noticed, in regular mode, that when you punch the right stick forward the Mavic slowly/gradually starts to speed up. The response just isn't as responsive/punchy as a Phantom. Is that why there is a sport mode? Is this normal or do I need to caliberate something? There was probably 5mph winds which maybe played a part in it but I just noticed the slowiness in responsiveness. It seems more responsive going vertical than going horizontal.
