I looked at buying an immersion RC Vortex Quadcopter but was scared off by the price. I found that i could buy most of the Chassis parts from their crash kits 1 And 2. I made the bottom Chassis plate from a small sheet of 1.5mm Carbon fibre. I then cannibalized my Emax 250 Quad for the parts and fitted them into the Vortex Chassis. Total cost to build was approx £65.

Its a tight squeeze to get all the components in.
