I just recieved a used cx today. It flys great but it turns/spins left and right (yaw) very slowly. It also make a loud screeching sound and slightly twitches its tail every now and then. It hovers great and flys for about 8 mins.
I've replaced the motors,gears,shafts,bearing,blades and have fine tunned the swash plate/ trimmed/ gearmesh/ balanced.
Now my CX2 can spin like crazy both ways shouldn't this do the same.
I think its the 4-1. Any thoughts or Ideas?
