Skyrc Toro 160 lost calibration

[lastplace]

Hi guys has anyone had any experience with there Skyrc esc lossing it's calibration setting each time it's turned off. If I recalibrate it it will run fine, I can turn off the transmitter . Then turn back on and all still works but if I turn off the esc . Then turn back on it just sits there flashing away looking for a signal from the receiver. I did find put that if I try and recalibrate it when the sanwa Exes X transmitter was set with anti lock set to active it would not complete the calibration process.
