my project is to build an all solar enduro electric glider. I have figured
out the air frame and I need to figure out the electronics. for anyone
who knows rc planes I am using the Great planes 400gd electrifly system
that is rated 7.2-8.4 volts
max continuous amps:22A max
internal resistance is .0036( i dont know the unit)
I was thinking of using 30 solar cells (15 in series with an additional
cell in parallel) 15 cells equal 7.5 volts at 7500ma
I was hoping running the second set of 15 cells in parrallel would
increase my current so the motor would not overload the cells. each cell
is rated 500ma at .5 volts.
if this is correct( I doubt I am right about it though lol) I need to
construct a powersource that can hold a charge of 5v at 1a for atleast
5minutes. (just incase I lose power from the cells)
another thoery I had was to let the solar cells charge another power
source and the motor runs off of that (ofcourse I wouldnt run the reciever
and the motor of the same source) so that the solar cells would not be
subejected to that type of draw.
please help me in any way shape and form (I can read schematics) feel
free to take any info and draw up shematics, because this will be entered
into the annual sciece fair if it is successful.
thanks alot for the help
