Last fall I crashed my P3A, recovered it and sold it on Ebay for $500. All winter I was excited about the rumors concerning a P4. Finally it was released and I knew to wait. Don't be a beta tester. Wow, the price of $1400 seemed reasonable to a degree. With a battery you are close to $1600. Then the reviews started coming in. We know them by now, short battery time and shorter range. All the while I'm watching prices on P3P falling. Now I see a brand new in the box P3P with an extra battery for $900. OMG, $700 cheaper. Is collision avoidance worth $700? I don't think so. So I jumped on the $900 deal and it arrived today. 1 year ago this bird was $1250. Waiting for the remote to fully charge and I'm back outside! P4 maybe next year for $700, but they will have had to fix it by then.
