however in the interest of terms..... ''Spoilers'' are used predominantly on sailplanes to reduce lift.
Yes. But on some planes, one spoiler can be raised while the other isn't, to induce roll. In full-scale aviation, that's called a ''spoileron.'' In RC, people seem to use the term''spoileron'' to refer to ailerons that can both be raised at the same time, to reduce lift. So the question is, are we using the same term - ''spoileron'' - to refer to two very different things, or is there another term for ailerons that can both be raised at once? It's not unheard of to use one term to refer to different things, and since nobody has offered anything different, maybe that's what's going on here.
Agree.. I see this when I fly on the commercial airlines however they are also in the back past the high point of the wing.... so not a true "spoiler"...
I offered my longwinded explanation because of this statement:
> spoilers that can be used asymmetrically to achieve the effect of ailerons"
Being used asymetrically takes them out of the realm of "spoiler"
