Scratchbuilt balsa night flyer "EVE-FLYER" (pics and video)
My latest project, a scratch built balsa night flyer.
I framed it up in one weekend, and finished it the next. The wings contain 14 ultra-bright 5 mm LEDs (I believe they are 5000 mcd) which are powered by a single Li-ion salvaged from a cellphone. More LEDs will be installed on the fuse and tail soon.
I am running a hacker A20-50s motor, 9 amp ESC and a 1320 3s lipo
The wings have only a single carbon spar and covered with parklite covering (great material btw). A carefully bent aluminum joiner glued into the fuse slips into the carbon spar and gives it the proper dihedral. The hold the wings in place, two nylon screws thread into a small plywood block on the inside of the inner rib. I made the cowling out of a mozzarella container, and the landing gear came from a mini funtana. Simple 1/4in balsa sticks painted with water based krylon paint form the fuse. I also fabricated a simple steerable tailwheel out of some piano wire. I didn't make ailerons, but maybe in the future I will add them.
It really flies fine the way it is, Very slow and docile, It makes an excellent parkflyer and is a blast to fly at night or dusk. The LEDs are so bright I can see them even with the Florida sunshine.
If I were to change anything I would make the nose a bit longer, as it is a bit difficult to balance with such a light motor. The incidence might need a bit of fine tuning as well.
Here are some pics fro your enjoyment!
