Hi Guys,
My 49Ah battery weighs 14kg. It's a pain in the ass to take it out after every flight for re-charging. This is because its difficult to break the grip of the of the velcro needed to hold it in place but also it's very awkward to reach into the fuselage to get it out with the windows on.
I'm interested in extending the charger cable so I can leave the battery in place permanently.
If high air temperature on the ground before takeoff is a problem for the battery, I would consider using something like an ice pack; in a waterproof bag of course.
Phil

Hi Robert
Battery one: 45 X 29 X 9 cm Battery Two: 58 X 45 X 29 cm
On the floor there are 2 balsa wood pieces, with the height of 5mm, so you can put the battery crosswise in the cage.

Phil -
I like your idea to leave the battery installed while charging. Please let us know if you are able to accomplish this.
Cheers, Mike Leger

Hi Mike
Its possible to charge the batts when they are installed. but due to the weight i take them out of the cage when i put the swift in the trailer.

Hi Urs,
I am curious, why do you have to take the batts out when you put the cage in the trailer? Is it because it makes the cage hard to lift or move?
Thanks, Mike

Cheers, Mike Leger Hi Mike, I charge the battery in the fuselage inside my trailer now but it's awkward to do this. The fuselage nose points forwards away from the trailer's tail gate so I have to crawl inside from the front and plug the charger cable into the battery from that side. Instead of extending the cable, I'll probably modify the fuselage mounts to allow the fuselage to be loaded into the trailer backwards. Once I get some time at home, I'll do this as I'm working 300km away.

Are any E Swift pilots using a rapid charger for their battery. If so, what is the charging time compared to the standard charger? Also - what is the source for a rapid charger?
Thanks much, Rich

A short report for our club's homepage from June 2020 about the "unknown aircraft" SWIFT light E, the first electrical powered airplane at EDGP (translated with DeepL): Electric flight in Oppenheim
Drones, small model airplanes or model helis - yeah, sure, we know them! No, a real airplane, with a pilot. Oha, that must be big and heavy, so that it can also carry the battery.... On the contrary: not even 90 kg, and that with battery! About 12 meters wingspan and a very short fuselage with a folding propeller at the tail: the SWIFT light E Flying for hours with just 3 kilowatt hours of electrical energy on board - solar energy makes it possible! The electric motor in the rear of the fuselage is used for take-off. It has an output of 10kW and drives the carbon folding propeller. After a few meters of taxiing, the SWIFT is in the air and then climbs at a remarkable 1-2 meters per second. After a short time the power can usually be reduced and when the first usable upwind is reached, the motor is simply switched off and the propeller folds backwards with little resistance. By then, about 1 kWh of the battery, charged at home with green electricity, has been used up. So there are still two thirds of the stored electrical energy left to overcome a thermal drought on the way, to cheat your way home or at least to an airfield after the end of a thermal, or simply to take off again after a landing. And what about solar energy? The SWIFT is actually a glider in the "light air sports equipment" class. As such, it is designed to use updrafts - usually thermals in this country - to cover long distances or simply to gain altitude so that the pilot can enjoy the view. Thermals are created by the sun. It heats the air on the ground. It bubbles along for quite a while until it finally can't hold it on the ground any longer and it rises upwards in the form of an updraft tube. On a small scale, you can sometimes see such "dust devils" on dusty dirt roads, spinning and swirling their way upwards. Gliders, like birds, use these thermal updrafts to climb to altitude and can then glide considerable distances from this height. If you want to try it out, just come and visit us at the airfield. For sure there will be a pilot who will take the interested guest in a two-seater to show him how to fly like a bird. aeroclub-oppenheim.de/elektroflug-in-oppenheim/
