Bought new Tactic TTX650 trans MAY 2013.Installed in airplane July.CHanged to Mode 1.Needed to reverse elevator and throttle channels.First flight needed to add down trim for level flight.While moving trim switch forward (up) I acually received up trim.Back on the ground I discovered the trim does not reverse with the channel reverse on any channel that you reverse. Trim stays same as when channel is in the non reversed status.Called Service Dept and explained situation.they told me that is NORMAL.THAT IS NOT NORMAL.Have 9 other trans of various brands and all work correctly.Have friends with Tactic 650 trans witch all work correctly when channels are reversed.WHAT GOES.SORRY FOR THIS PURCHASE.Have since sent trans to Service Dept on 8 /5/13.Not to optamistic.
