There are generally two micro-helicopters ( indoor ) in the RC market. I have already planned to buy one of them as they can fly inside the living room and even take off on ours hand. Unlike those operated by gas, these electric helicopters are very clean and give out no terrible noise at all. In one nightfall, I visited a web site, which is about how to make a hand made RC helicopter. I was totally impressed and started designing my own helicopter. Here is my helicopter:
