Some owners have stress crack problems and others don't. It's hit or miss. I just had my P4 replaced under warranty 2mos ago due to body cracks, it was 9mo old. However, I don't regret buying the P4, we've done a lot of traveling together. I've flown all over the country and it's been very reliable and amazing to fly. I have photos and video of places that were unimaginable 5yrs ago. No other brand is going to give you a better value for the dollar, cracked body or not. The software and features of the P4 are way better than anything else in this price range, bar none. The only thing I was disappointed in was the GL300C stock controller that limited the range to less than a mile in most places. I had to buy an Inspire GL658A to get the normal 2 to 3mi range I was getting with my P3P. With that in place, it's a great bird. But if you have the money, buy the
P4P, not the P4 or P4A. The range will set you free, not to mention the 20mp camera.
