That would help you in avoiding costly mistakes and your model plane will be saved from the reduced crashing experience. You can take it to your garden or any other empty plot of land for your first flight. If the ground is smooth, you could make it takeoff from there or you can even make it take off with one person holding the plane and then leaving it gently. Once you get the hang of it, you can then proceed to do some stunts(特技) like flying loops, rolls and inverted flight The joy of learning something new will keep your interest alive in this hobby Once you are well skilled in flying battery-operated model planes, you can also graduate to gasoline-powered planes.

Get that RC model air plane and take to the skies with your feet planted firmly on the ground. 语言点津: familiar with与 familiar to辨析 familiar with常可表示 1.“熟悉的”,即 having a good knowledge of sth; 2. 友好的,过分亲密的,不拘礼节的”,即 fri
