Lego Micro Quadcopter
Recently I managed to get hold of some spares from a few Hubsan x4 micro quads. I have been playing with these quads for a few weeks now and have many questions about how the set-up affects the flight characteristics.
Would angling the blades inwards make the quad more stable at the cost of efficiency?
Would a smaller frame make the quad more agile or would the props cause interference with each other?
Would angling all the props slightly forward make the quad handle more like a plane?
Could the quad support a V-tail set-up?
The final result fly’s nice and weighs the same as the original frame. Adding to this could cause weight issues but I still have a few grams of lifting capacity to play around with. This frame is also slightly smaller, each blade almost touches the one next to it. this seams to have made no difference to performance but the quad seams to corner much nicer due to the lower centre of gravety.
