RE: Spoilerons or Flaperons?
PilotFighter, What you're describing is a "harrier" approach. Hanging the plane on the prop, and desending at a high angle of attack (alpha or AOA). While that "works" for some models, it's a really bad idea with others. Full scale pilots would call it the back side of the power curve. Anything with a high wingloading and lower power-to-weight ratio isn't going to do it very well at all, and any kind of gust at the wrong moment would easily result in a stall-spin-crash. Models with enough power to simply power up and pull out of that kind of thing will be fine, but I wouldn't do that with anything else. (yes, I can do it, sometimes I do it for fun, because I can. But I don't teach it as a normal way to land).
