This is our Mark 2 aircraft which although is the same size as the Mark 1 it is very different in almost every other way. The main difference is that the camera now points out the right side of the aircraft and not out the front. This means we can circle our target while taking pictures instead of having to fly many passes, it also reduces drag and so benefits the overall performance. Performance is also improved by doubling the power of the motors, this enables us to fly from smaller areas more safely. back
