1. Programming Overview This procedure takes into account the difference if any between your radio s pulse widths and the pulse widths assumed by the HFP 10 programmer for all radios and calculates an appropriate ratio A preliminary set of calibration numbers are obtained from the HFP 10 programmer based on this ratio These numbers are tested by using your radio and accurately measuring the servo arm angles with your AeroPerfect Digital Control Throw Meter The final programming numbers are then calculated by the spreadsheet based on the measured angles Before we get started we d like to say a word about about the direction of rotation CW clockwise and CCW counter clockwise is mentioned in two file C My Documents Airplane RC AeroPerfect Website aeroperfect_users_manual html 3 26 2007 AeroPerfect User s Manual Page 13 of 36 contexts within this procedure One describes which direction the servo arm is rotating while the other refers to the direction programmed by the HFP 10 Program CW CCW If you program your servo for CW clockwise servo rotation using the HFP 10 it means that wider pulse widths will cause CW servo rotation Conversely narrower pulse widths will cause CCW servo rotation Also if you program your servo for CCW counter clockwise servo rotation using the HFP 10 it means that wider pulse widths will cause CCW servo rotation Conversely narrower pulse widths will cause CW servo rotation On our Ec
