Don't know but batteries last 8 minutes in the PD and the DJI lasts 25 minutes and has tons of features. Guess you get what you pay for - but I like both.
yeah, it may be the equiv of the VW Beetle of chopper drones but it's rather amazing you get that much tech (HD cam incl) for $300. the DJI probably has a superior operating distance as well, they warn you about sending the parrot out of range.
