Forward swept homebuilt EPP night flying wing ... rare daytime flight


Dusted off one of my night flyers for rare afternoon flight.
Heavy plane, strong wind.

My forward swept scratch built planes are only swept
about 3" or 4" forward. Doesn't take much.

This wing is EPP and uses double a-frame FG rod spars
similar to combat wing construction.

The fuse is styled after Flying Foam's Nurf.
The fuse built as 2 pieces, hollowed for batteries and electronics,
then glued. All EPP is laminated with .003 clear lam.

LEDs embedded first and tested. Separate 3s battery for LEDs.

Lately, been building EDFs....planning on trying an EDF night flyer....
although props are way more efficient... for sure.

Here's a short video of a day and a sunset flight, best viewed
in HD.

Awesome #6
Would love to mimic the design, maybe in Depron, any drawings or more detail on dimensions?

Thanks, I get some nice comments
at the field.

This was a one-off.

I had previously built a kit
from [now out of business]
Flying Foam, called Nurf.

Nurf was a good flyer but I
decided to make changes which
you see. Twin fins, wider fuselage, etc.

I ordered just the wings from them for this
plane, changed airfoil to EP341.

Nobody has filled the void they left...
so now I hotwire my own stuff from EPP.

No more Depron in USA.

Have fun.

Depron

if you really want some, you can still order it from the UK. www.depronfoam.com. Price and shipping aren't too bad. Or Model Plane Foam from Springer at www.modelplanefoam.com. This is similar but not quite as brittle as Depron.

Of course, EPP is good stuff too
Cheers and happy building

Thanks,

I do use some MPF.
I have another source for 2" EPP
so mostly use EPP now.

Oh, I changed the sparring on
my version of the Nurf...see green
lines on PDF.

Didn't like their nail joiner, it allowed
wing to flex more longitudinally.

Since I added more powerful motor
I wanted rock solid wing...works good.

Not sure how you would do spars in depron
but their bent nail single spar was not good.

Their wing is long and thin...OK fast too, but needs
strong spars.

The double a-frame spars I added are typical of
an EPP combat wing build. A-frames both top and bottom,
same position. Creates I-beam strength,
very strong in EPP.

Have fun, post pics/vids.
