A RC that always works for me is feeling your sorroundings. like for example put your hand on the ground and look at your fingers stretched out on gravel, cement, grass, a table top (Whatever your holding) and usually either your hand will morph into something strange (7 fingers, missing fingers, talons, etc) and/or the ground will be moveable, shapeable or your hand will go thru it. and weather the ground or my hand tips me off, it always works for me. good luck !
