I was flying my Blade over the holidays and after putting in a fresh battery I had a huge reduction of power. It would hardly maintain a hover. My first thought was the motor finally had died but I switched the motors and had the same problem. Then I thought it might be the battery so I charged the other with the same results. I then switched the motor into another helicopter that I had been using as a spare. It flew fine hovering slightly above mid-stick. I checked the mesh between the motor and the gear and made sure the gear was not rubbing anything. The previous flight was fine no crash or hard landing. It has been a while since my last crash. I was hoping that someone would have some thoughts. I am flying the nine tooth motor with a thunder power 900mAh
