Blades are installed correctly. I bought the heli used so I don't know what gyro it had in it. I took the gyro that is in it now out of my new heli that I had only test flew. The gyro and servo are new and have not been crashed or abused and it worked fine in the other heli. I don't really know what to do. I guess I'll just make the drive and have somebody look at it for me.
