Roadrunner is a flying wing aircraft designed to demonstrate the performance of the double taper delta planform for high speed flight and low speed landing.​ The aircraft is currently the fastest electric UAV ever at the University of Southampton, with a level flight top speed of 120mph. 

​

The aircraft structure is a carbon fibre monocoque, laid up as two 45° bi-axial plies onto a core of foam and lightweight 3D printed plastic.​ It is capable of +/-10g, with double redundant flight control surfaces and a single tractor propeller driven by a 2.5kW motor.
