Hey my worldwide located electric powered friends!
Me and a my "crazy projects mate" (Stefano, aka giubi.s) made a solar plane
It is 3 yards of wingspan (2.3 meters to be precise), glassfirbe homemade fuselage and carbon/balsa wing.
28 panels are connect in 14s2p and are inside the wings and on the tail.
Motor is hacker b2015l + maxxon gear 4:1, esc is 18A from hacker.
The panels under the trasparent oracover indoor give us 25 watts on a great sunny day, barely enough to fly, so we have a 3s lipo with a ground controlled switching regulator to make the battery and the panels cooperate.
FLying with such low conspumptions requires an insane precision, so the plane is flown by ardupilot 2.6 (thermopiles version).
We worked on it for a bot over a year, biggest issue was to have the battery cooperate with the panels.
A few days ago we managed to keep it in the air for 142 minutes, wich we think is a great succes and will be improved since that day was very wind and the autopilot was not propely set yet (5 times up from almost ground to limit of visibility and back, a big waste of energy I`d say).
Here are some pics!
