X2 on spoilers for an aerobat. Of course, it depends on the plane - but many is the pattern/3D model I've had that needed a headwind to make a perfect landing. On those low/calm wind days, it was a bear to land - too drag free to slow down with any practical base leg length so it would either just float on past, or have to be forced down a bit early, which made the perfect touchdown not so perfect. Adding spoilerons was always the solution. They added the drag needed and greatly stabilized the plane so it came in like it was on rails. Properly adjusted, with just a tweak of elevator mixing if needed, and it was just a matter of managing power to shorten or stretch the approach.
I've gotten fancy on my current - have a series of logical switches so they only can deploy with a given switch flip AND lower throttle setting. Advancing the throttle, like for a go around, automatically retracts. They are timed to retract slightly after, with a bit of slowness, to give a bit of time for the airspeed to build. Makes me look like a far better flyer than I am.
