Well, a little spoileron helps on your harries and waterfalls, but you dont want it for hovering. In that engine range you will get a few replies. I would personally put that 61 two stroke in a Funtana 40 or a U-CAN-DO(ugly but good 3D beginner plane). The Funtana will take a lil bit more getting used to but it's a beast when you get good at it. good luck.
