British electric flight association
The Association was formed in early 1990 in order ‘To Encourage and Further all Aspects of Electric Model Flight in the British Isles and Elsewhere’.
Whether you are a newcomer or an experienced flyer, the BEFA caters for all levels and interests, be it free-flight, radio control or control-line model.
Airbus e-fan concept can sound a little outdated, but it is one of the best methods developed so far for pilot training.
The APEV Pouchelec can be considered as good for amatuerish people but they work the best and they are light weight transports that are easy to access.
The concept of flights using solar power is not long way off. Astroflight sunrise is one such example as it works flawlessly on solar power.

News and Events
Electrical lights or electrical bulb is a device that produces visible light which is produce by the help of direct or alternating electrical current. It is the most famous form of artificial lighting and is becoming an essential commodity in the modern day society.
History of electrical lights:
- Artificial lighting began a thousands of years ago, and has been refined constantly to the present day.
- Starting from control of fire by early life and later evolving it to use it in oil lamps and candles.
- Furthermore, in the late 17th CE, scientists started experimenting with gas lighting and produced he first light gas.
- In early 1800’s, the arc lamp was invented followed by the first electrical lamp over 10,000 lumens.
- In the mid 1800’s Thomas Edison produced a 16-watt that lasted 1500 hours.
- It continued to evolve until 2008 where Ushio Lighting demonstrated the first LED filament.
- In 2011, Philips, won the L Prize for LED screw-lamp which was equivalent to 60 watt incandescent lamp for general use.
Parts in an electrical lamp:
- Lamp is a replaceable component that produces light from electrical current.
- Lamps are usually made of metal, ceramic, glass and plastic which secures the lamp in the socket of the light fixture.
- The electrical connection to the socket is usually made with a screw-thread base, two metal caps and pins. A bayonet cap can be replaced for a metal cap.
- The part which produces light is called a filament. It turns white-hot when electrical current is passed though it and that is the part which emits the light.
- Gas discharged lamps produce light by means of an electrical arc through gas.
- LED lamps produce light by flow of electrons across a space in a semi-conductor.
Types of lights:
Incandescent light bulb:
It consists of a heated filament inside a glass envelope and emits continuous light. It has a lifetime of 2 to 20,000 hours.
These are incandescent lamps that use a fuse quartz envelope filled with only halogen lamp. Its optical spectrum is continuous and has a lifetime of 3000 to 6000 hours.
It has a mercury line and phosphor as its optical spectrum. It has a lifetime of 8000 to 20000 hours. It is available in different colours according to the temperatures.
Metal halide lamp:
They have a Quasi-continuous optical spectrum and works for 6000 to 20000 hours. They emit a cold white colour.
It has a continuous optical spectrum and has a lifetime of 15000 to 20000 hours but emits a pale green colour light only.
It has a narrow line optical spectrum and can be used for 18000 to 20000 hours. Another advantage is that it emits various colours according to the temperatures.
Electric flights are in progress. But scientists, based on their research keep updating the information.
- If we permanently run out of fuel in future, the source of travelling will be a dream to many people. For short distances we were already presented by the electric bikes, electric cars etc. Similarly, the Electric flights are designed hoping for the longer distances. But it ended up with short distance.
- As we are able to fly only short distances, we can use airplanes as cabs instead of cars. We can be fast in reaching our destination. Thus we can reduce heavy traffic problems and air pollution.
- There will be reduction in the emission of carbon dioxide. Thus, we can reduce the air pollution.
- The noise pollution can also be reduced once they finish their research on electric flights. As electric motors doesn’t create much noise.
- The cost will be very low as electricity is cheap compared to fuel.
- Nowadays, the usage of solar panels came into existence. Hence, in this project if we get the usage of solar energy then that would be a great success. But if we run short of solar energy, electric batteries should be used and it should give sufficient power for the whole journey.
- The weight will be light and the flight runs smoothly.
- If the airplane flies high in the air, the content of air will be less which can be in our favour once we find how to reach heights compared to other flights. As we have an idea how to fly even when there in less air atmosphere.
- It’s better to run the electric flights with batteries. If we run out of charging, its better to convert to fuel mode. So that we reduce the pollution atleast to some extent.
- We are able to travel only short distances. But the long heights, we are unable to reach like the other flights.
- Have a clear picture of many benefits of electric flight over other flights by using electric motor. But there is no proper idea how to fly high using electricity as source is the major question everyone does have.
- They have been working since many years and expecting many more years. Approximately 10 to 20 years to get succeed. Maximum of 30 years is the estimated time for the new innovation i.e., Electric flight.
- Present innovation with batteries, its major drawback is the battery has to be recharged once it gets discharged.
- Recharging a battery is the time taking process. Else we need to carry batteries required for one journey which is also a complicated task.
- There will be a problem with thunderstorms. As electricity passes through flights, there is a chance of getting short circuit.
BEFA is an association for Electric Flight enthusiasts. Our organization aims to promote the Electric Model Flight in the country. Membership to our group will provide you with the following benefits:
- Monthly feature on Electric Flight models and product reviews
- Tips on construction techniques
- Technical Workshops conducted by experts on Electric Flight
- Online help offering professional advice and assistance on basic troubleshooting
We also have an online marketplace set for specialist flight model traders to showcase and sell their creations. We also put up a collection station for surplus parts that you wish to dispose of.
We are also proud of our annual competitions for fun-flight and league events.
These are just some of the things that you can gain from joining our organization. We expect more to come as we grow our membership and successfully promote the love of Electric Model Flight.
Kindly look at our annual calendar for this year’s activities. You can also check out our prior year’s schedules to see how our organization has evolved.
