mine needs about 4-5% up elevator with rudder, but absolutely no aileron mixing. So whatever the dihedral is straight out of the box, it's spot on.

I am using an APC 16x8 prop on the 110, burning Wildcat 30, which gives superb vertical. I have flattened the throttle curve slightly around 1/3 to 1/2 throttle though to desensitise the throttle response around the power level required for prop hanging and that worked really well. With this much power the hardest part I find is actually keeping it from climbing...
