While I have flown RC for years, the P4 was my first drone (and first RC purchase in nearly a decade). I broke a prop flying it inside (GPS really does do wonders with stability) but it has been great. Then I thought "****, was this worth more than my computer" and considered downgrading to the P3 or P3A (for at least half the cost), so I picked up a P3A the other day. I won't lie, I was rather disappointed in the P3A and feel that the P4 is an upgrade from the P3 for a few reasons: 1) P4 is MUCH more stable while hovering, or just in general. I don't know if it's because it weights a 1kg more, or because of the dual compass/IMU, but the thing is really rock solid and gives me more confidence flying around trees. 2)P4 P-Opti is actually the perfect speed and stability. The 22mph governor is nice for when you hand the controls to a newb and show them how to fly. The P3A just screams along at 35+mph. 3) P3A's gimbal 'drifts' slightly, whereas the P4 gimbal stays put. 4) Build quality: not to sound petty, but the P4 feels NIGHT AND DAY more durable and better built than the P3. Is it just me, or do others feel that way? I felt naive for jumping into the P4, but after considering the downgrade and purchasing the P3A, I am having second thoughts.
