I thought I would pass on a tip for setting up three position flaps up on a DX-7 and AR7000 Rx. Flap movement half way down listed in the manual is 1/2 inch travel and full down should be 1 3/8 inch. In order to get the correct throw measurements I set my servo center at half way down flaps or 1/2 inch. The up flaps and full down flaps positions were then set using end point adjustment or travel adjustment of 33% up flaps and 45% down. I then realized I had to rebind the Tx/Rx with the flaps in up position with the new travel adjustment.
