I have been looking at the J.R servos trying to figure out which one to get for the elevator on my my .60 G-300 .I think ether the 4131 or the 8101 might be good.I do not see any real difference between these two , does anyone know what makes these two different ?

Thanks P.J

The only difference is that 8101 are newer. The rest is the same.

JR's 8101 servo is based on the design of the world famous JR 4131, and shares the same 90 in./oz. output of torque and .24 sec speed specifications. The significant upgrade to this servo is that it features an output shaft that is supported by two ball bearings that are placed more than twice as far apart, providing improved performance through improved radial shaft support. This innovative design significantly decreases output shaft radial freeplay and increases accuracy dramatically especially under heavy loads
