digital servos
Digital servos work great for 1/12. I've tried a number of different servos for 1/12 and the best i've found is the KO PDS-947. The Futaba 9650 (?) digital also works well. If someone told you digitals "flutter" they must have had a bad servo. Digitals draw more current than regular mini servos, but it's never caused a problem for me (unless I forget to charge the reciever pack).
