i believe this heli has had a hard life before me and the main shaft was bent when i got it but i replaced it the blades were also damaged but i replaced them and since damaged them because everytime i lift off it leans and hits them could it be play in the upper portion of the head doing this?like i said when i spin it up in my hand you can watch the blades tilt around almost as if someone was controlling it alittle bit but the swash plate isnt moving if this isnt normal i think it might be contributing to my problem .as far as i understand it is normal to tilt to the left but this is severe (i think)
