A lot of guys at my local scene are using Align DS610, DS620 and DS615 (recently released) for their throttle. Seems to be very accurate, fast and much cheaper then the likes of SAVOX. not too sure if anyone else in here have tried Align servo in their MT, SCT, Truggy, Buggy. I use Spektrum 590 for my throttle..no visible lagging or center correction...seems to be accurate for my MT throttle use.
