Ok. Guess what I found the problem. And again thanks for all your input.after replacing the 3in1, I rechecked the motors and they were good, all connection where good. I thought hhhmmmm.... I have and old hobby king 6 channel rx, that will bind with my turnigy TX . So I set the esky 4 channel TX aside and replaced the esky rx with the hobby king 6 rx, and poof it worked again. After a few reverses in the settings I was in the air again. Apparently the 3rd channel went out on the esky reciever. Never figured that one...... Now I have a tail way short wag and fast when I spool up. This is a co-axle 4 channel heli. So not sure if I just need to adjust the 3 in 1, or if it might be balancing/tracking of blades (though they are plastic). I know with my 450 I would just adjust the gyro. Any ideas? I an get it to hover it just shakes real bad.
