It sounds like you are waiting for the plane to float off the runway without any elevator input. If this isn't what you are doing, correct me.

I can't imagine raising the ailerons 1/16inch would extend a takeoff that much. Don't be afraid to pull the elevator. Most planes can lift the front wheel in 50ft. As you build ground speed, introduce more and more elvator. Just as the plane lifts (6inches), reduce the elevator to keep the nose down and avoid a stall and she should climb nice and easy.

Also, did you notice your elevator trim was off after you adjusted the ailerons?
