~ robot helicopter currently in production has a take-off weight of 15 kg
~ it can be operated under Dutch legislation for small unmanned aircraft weighing less than 25 kg
~ it can carry a payload of approximately 2 kg. e.g. a high quality videocamera, with an endurance of an hour
~ due to its low weight and relative small dimensions, robot helicopter is easy to transport, e.g. in a small van, and quickly deployable
~ thanks to its ability to hover and vertical take off and landing,
~ it requires no special infrastructure such as a runway for take off and landing
~ a robot helicopter with its custom built control system can be safely operated after a minimal training
~ the fact that robot helicopter weighs far less than a manned helicopter means
~ it has a much lower impact on its surroundings such as a very low noise level and much lower emissions than its manned counterpart
~ robot helicopter is considerably cheaper both in acquisition and
~ operational cost compared to a manned helicopter while it is able to serve a large number of the same applications
