Do I need a licence to fly a paramotor in the UK?

Not at all. Although I would strongly recommend qualified training as teaching yourself is extremely dangerous. Learning to paraglide(free-flight) first to build up some experience before adding a motor unit might be a wise move.

Can I fly anywhere?

No. There are certain airspace restrictions governing our freedom but we are allowed to fly in uncontrolled airspace(F & G). Refering to up to date aircharts enables you to produce a flight plan that will prevent you from straying into flight corridors, military and commercial air traffic zones and other prohibited areas. Launching and landing must be carried out on non-public areas with prior permission from the landowner. An unscheduled landing must be followed up with seeking out the landowner and informing him/her of your actions.

I am currently a free-flight pilot, do I need a bigger wing to fly with a motor?

That really all depends on several factors. If you are light on your wing then the motor weight will be of no consequence. Most wing manufacturers encourage you to be a little over the free-flight weight range to improve collapse resistance and give a slightly higher airspeed. If you are near to or over the top end of the free-flight range then it is really down to personal preference. Being over the top end might require a longer and faster take off run before enough lift is generated. Or, you could opt for a larger wing and reduce the energy required to launch.

Is there an option for a larger fuel tank on the Eggmotor?

Currently there is no information for a larger tank but it would be relatively easy to retro-fit one. A 9 litre 'karting' tank fitted under the engine and a pulse driven pump would be the main items required. Duration with the standard 3.6 litre tank should exceed 2 hours as long as the pilot climbs to the minimum height and cruises. Compared to other paramotors this is admittedly a little bit short. However, the aim of the Eggmotor philosophy is to provide a simple, inexpensive paramotor for the masses. If you feel confident enough then feel free to give it a go.

There doesn't appear to be any protective netting, why?

It would be relatively easy to install netting of some description. The production chassis prop circle will be smaller than shown on the prototype picture and so the likelyhood of a stray line entering it is quite small. Also, if a pilot ensures a correct engine starting procedure then that should eliminate any chance of a hand/prop incident.
