I'm using the Futaba 4PS. I will have to check the nuetral. It ran a few laps fine before I had any problem. I had recently adjusted my throttle forward EPA from 100 to about 85. I also tried setting it on a new model on the radio with factory defaults except for reversing steering. Did a calibrate also after that, but still same issue. I will check my nuetral when I get home. About where is it normally?
