I have ordered this servo for my cyclone racing car. It's super fast and powerfull, and from day one i don't have any problem with this servo. I'm using only best Hitec, Futaba and Kopropo servos for 1:10 rc cars and among them this is a true winner. I wish i can afford me another one for my second car! Excellent servo for RC car racing!
I ordered this servo december 2007. When it arrived, the servo-motor was blocked and burned when I tested the servo for the first time. Later on, the Ko Propo-people diagnosed it via email as being the case-screws that were tightened too firmly. Unfortunatly the harm was allready done.
Also, unfortunatly, the servo is STILL not replaced (aug. 2008)?
But I bought another 2413ICS, and this one functiones as a beauty! Very fine stuff!
