In order to use the faster frame rate, you need all digital servos, as the analog can't follow the faster frame rate. If your Tx works the current analog servos, I don't think you will find any electronic issues, as the digital servos are equally capable of following the slower frame rate. The pulse widths and voltage changes to create the pulses are well-standardized, these days. Whether you would experience any "flying feeling" differences between functions with and without digital servos, I don't know. </span><o:p></o:p></p></div><div><p class=ox-38e69c4528-msonormal><span style='font-size:12.0pt;font-family:"Helvetica",sans-serif;color:#333333'> </span><o:p></o:p></p></div><div><p class=ox-38e69c4528-msonormal><span style='font-size:12.0pt;font-family:"Helvetica",sans-serif;color:#333333'>What functions are you ging to use digital servos for, and why?
