yes you can have it turned off and on by a switch or you can have it coming on when you are at 25% stick. I have mine on switch mode but i use the same switch theat gives me mode 1 mode 2 and normal then i have the three setting to allow me three speeds. normal set at 1750 mode one set at 1900 and mode two 1950. I also have dr set higher on mode two so the 3d is faster. and yes I do enjoy the 90. it is expensive when i crash it but the flying inbetween crashes is great. fast powerful and sounds great. also is fine on windy days it still flys just as well.....get one they are great.
