Hello I am the owner of 3 Syma 8’s and I have a major question for anyone that can help or guide me. The very first one I bought was for training, getting used to this type of drone and learning to fly it. I have to admit that it is a very user friendly drone and ez to fly. To my mistake, I let this drone fly too high and basically I lost control of it and never found it. I like the drone so much that I decided to buy another one and this is where the problem begins. After about 2 months of daily use the drone seem to have lost lift or power so I ordered another battery and it improved. Not to make a story too long, it got to a point that the drone would not lift more than 30 feet and down it would come every single time. I got so frustrated that I bought yet a third one and same thing happened to the third drone. I flew it for about a month, nothing but great flight time, and it slowly started to lose lift once again. In a nut shell I have 2 drones that are doing the same thing, NO LIFT, and I am looking for your guidance to fix this issue. Just an FYI I have swapped the motors on both drones, reset or calibrate it and that did not help. Please help. Thanks.
