I got 3 jr servos to send back again. 2 9000T are no big deal because I almost lock out servo savers & the gears just got worn/excess pay around center.I would say I got more than my moneys worth from both considering the abuse they took & their still in warranty.The 3rd is a 9000s & died in about 4 tanks.The S was a replacement for the recall they had & it buzzed louder & more often than normal during alignment so was probably bad before I opened the package but again still under warranty.Only complaint I have is JR warranty takes 1-5 weeks(experienced both extreames) but Hitec warranty is 1-3 days(I live down the road from them).Both brands have about the same life span & cost about the same.The best thing to remember as said above is ALL servos WILL die eventually.
