The guy who recommended the Savox servo's failed to tell you that in the US they are the Orion servos. I use the old 5955 st, and the 5625 throttle from Hitec and havent had any issues. And I will run them till they go caput. I like to try different brands of stuff I have used KO PROPO and loved them along with Futaba. I will probably try the Orion's next unless the price goes down on the HV JR's with the metal cases that are coming out soon I belive. They look promising, especially because you can use lipo without a regulator which is the only way i will run 1.
