Data for the design of a Vertical Take Off plane
using electric Ducted Fans
Fred Jordan,jordan@ltssg3.epfl.ch
The data below have been found only on the internet. They present various motor/fan/battery configuration in term of thrust & weight of a vertical take off plane. If you have any comment or experience regarding this kind of project or the use of high drain currents on type "R" battery, let me know ! Other people are working on the same idea (and were working before me), have a look there !
