Please note the following are my reasons for not buying the P4 and I think there are far better alternatives on the market. 1) The aircraft price increase can not be justified. 2) The battery price ($300.00 au) is far too high for the little gain. 2) Aircraft design is very bland and can only be called an update. 3) The camera has had very little improvement. 4) The camera 360 degree still has the landing gear in sight when filming. 5) Anti collision avoidance will not avoid small twigs. 6) Anti Avoidance only works with a minimum of 300lux (be careful filming at Sunset) 7) No provision for FPV goggles (HDMI?). 8) Extra 3 minutes fly time for a battery priced at $300.00 au, only 5350mah??. 9) No improvement on landing gear still unstable on landing (extra rubbers will not help). 10) No change or improvement with transmitter (still requires phone or tablet??). Overview; Too much emphasis has been placed on the avoidance system and relying on the market for beginners, however with the price point on the aircraft and specially the price point of the battery I doubt beginners can afford it when there are cheaper alternatives and just as good. For DJI to remain market leader they need to do more and innovate with forward thinking and vision to remain there.
