IMO - Order or go to your LHS and buy some HITEC servos. oh and keep your reciept.... I have brought a few servos off of auction sites and it did not play out well... Dont buy used and unless you know and trust the seller. Over the last year I have spent $$$$$$$$$$$$$$$ on servos suggested to me by local racers, including (yes J) a $200 JR HV servo - which for some reason drained my Lipo in the main at my last race in the the springs. I have used JR 9000 series with good results, just dont like the regualtor..... I happend to run into some Hitecs HV and they "seem" to be pretty good.
