I found the cure for floating!!! Mix in -20 of up ailerons (airbrakes) with -3 down elevator mix and it will take the lift right out of the wings on final. Mine floated right past me at about 6 feet on several occassions and I finally found this cure. The mix makes the plane very predictable on final and about 80% of the float goes away. It doesn't make it drop, just land managably. I'll just mount the BCMA stock and, if needed, add thrust adjustments later. Thanks for the tip!
