2610 do not set the tx to fix id. Just turn on RX (heli) first. Then Turn on the tx. Wait till both Led stop flashing and it should work wor. BTW: can't remeber if you need to set the tx to 2601 mode or 2801 mode......
hum...... which mode are your tx set to? I am not sure about 2610 rx. But I think you need to set the tx to 2801 mode if this don't work try 2601 mode.... And check the little antenna on the 4in1 and make sure it is not broken. And what happen to the led on the 4in1, flash slowly or quickly?
flash slowly there are some issue with your rx wor.... because when you plug in the battery the 4in1 should flash quickly. If the 4in1 bind correctly then it will turn solid red. If it flash slowly mean the rx have lost the receiver signal....
