jchuston that may be true for Futaba and OS but Hitec is not exclusively distributed by Tower(aka Great Planes).
Considering that Tower imports (to the US) Futaba (and therefore Hitec) as well as OS products
Tower (aka Great Planes, Hobbico) does import Futaba. Futaba and Hitec are in no way associated except for both using negative shift receivers and have a compatible trainer system.
