Hi Edward,

Thank you for your feedback, what I do notice is what you have told me in regards there is a 95% pulsing the SCR and honestly I do not see any difference between if 1-a is on or off at the time I fully it acelerated.
the serial number i am talking about is RC-3020-30 series 3000 and S/N 1A128583

Yes. I do have the handset to calibrate the spped control.
do you have a basic parameter to verfied them in a ramp traveling?

Kind regards,

Luis
