Whats going on ladies and gentlemen, new here and introducing myself. Part time photographer/videographer/hobbyist, picked up a p4 brand new for 1100, and just waiting for everything to come in. Not too shabby... My questions: -Has anyone already come up with a setup to make the P4 landing gear retractable? is it possible as compared to the P3? I always have to tinker with things... -Is there an alternative to paying $130 a battery on amazon?
