the thing that shoos me away from electric is how much it begins to cost when you get into larger planes. it costs a lot more than gas and gas has that cook ticking idle sound. a brushless motor (you cant go brushed with a larger 3d plane) will cost upwards of $300, and another $100 for a controller and another $100 per pack and while that eventually pays for itself in savings over gas, it still does not have that cool ticking sound.
