As mentioned before, they're the same as Team Orion VDS servos.
During last season I switched from an Ace 1015 to a Savöx 1256TG aka VDS 2015 for steering my RC8B - just because I was curious. So far no complaints at all. Will replace all my Ace servos with Savöx. Compared to the 1015 the Savöx are very lightweight, too.
