Led's are now easily bright enough to fly a plane at night. Left is my Fledgling
slope soarer which i equipped with around 70 led's of varying colours. Blue on the
left wing and tailplane, red on the right wing and tailplane, white on the fin and
rear fuslage section and orange around the nose. This made flying and orientation
in the dark no problem. The led's are wired in paralell with an apropriate resistor
on each one and powered with a 7 cell 650 mah AAA battery pack. They can be switched
off and on in flight using an electronic switch plugged into one of the reciever
channels. With the led's turned off the plane was not visible from the cliffs where
i was flying it.
My next project was a depron fun fly type plane, needing to keep the weight down
i am running all the led's from 2 650mah AAA cells, There are the circuit boards
of 4 cycle lights 2 green in the left wing and 2 red in the right, a circuit board
with 6 led's is inside the last section of each wing and a circuit board with 3 is
embeded through the end ribs. The other led's i purchased in an assorted bag from
a model show tool stall 5 green on the left tailplane and 5 red on the right,.
There are 4 orange led's around the nose. All of these seem ok running off 2.4 volts.
Here are links to 2 videos video 1video 2 .However will be much improved when i
can fins a couple of white or blue led's to go on the fin.
This is my latest project, a Ben Buckle Junior 60. The led's are set out in a similar
colour scheme to the fledgling with the addition that it will be a float plane and
have green led's on the floats. As the plane is built up I have covered the wing
tips, tailplane tips and fin with clear oracover mounting the led's inside, thus
lighting up the whole section. The led's for this have the appropiate resistors to
run of a 4 cell pack although most will still be powered separately to the reciever
pack. The led's can be switched off and on in flight with an electronic switch attatched
to a spare reciever channel. As This will be an ic plane and subject to vibration,
i have put 4 led's on a separate circuit running of the reciever pack in case the
main lights fail in order to be able to still see to land.
Left is my lightened president fun fly with leds, which is capable of droping a small delta plane also equiped with leds,
unfortunately on the test flight in the light the first one had a mid air with the plane that had dropped it resulting in the
wreckage shown below. In the third picture below is the 1st replacment under construction which on its first night flight
landed out of sight behind some trees and was never found, presumed stolen. I am currently building another.
Above is the fun flys hatch. The outside is made out of white 3mm depron,
the inside is made of grey depron coated in reflective silver tape, sandwiched between the 2
is 3 white led's making the whole hatch glow white.
