Based on the AGFRC A06CLS V2 servo but with the more common 1/28 scale 20T Spline that comes in other servos like the GL line of servos and the V1 A06.  This is the perfect servo for your RX28 or other 2wd 1/28th scale kits.  The servo comes with a stealth all black wire leads and much shorter so that you can get that clean factory look.
