Are the gears in the JR 505 & 507 the same in all. I took apart 3 JR servos ...gear train looks same, but all three servos had different motors. How many different motors did they put in them over the years? Thanks John P.S. I do need a set of gears-

The 505 and 507 do have different gear sets, the part number for the 505 is JRPSG505, and the part for the 507 is JRPSG507. As for the motors, I do not have any information on at I'm afraid.

Dan: Thanks for the quick reply. On the motors..... I do not need a motor....just kinda noticed some are not the same. I think the newer ones have different electronics inside also.

No problem! That could be, I'm not sure if any changes were made along the way.
