I don't know how much carryover there is from the Yellow AT-6 (101") to yours, but I have found that a 13% mix from flaps to down-elevator is about right ... I use about 45 degrees of flap for the "full flap" setting and 15 degrees for a "partial flap" setting for the downwind leg (I have the flaps on a 3 position switch).

I second the comments about power-on landings and the high sink rate and the "AT-6 Hop" on landing. It really forces you to get off the elevator as soon as the mains are down, or you can find yourself having popped back up, nose high at low airspeed, with the usual predictable results :-(
