This is a little project i started working on over a year ago. Just playing around in a cg calculator looking for interesting silhouettes. It was going to require a little bit of "messing around" with my windyhillhobbies cnc cutter as it has much greater than 45 degree sweep. After doing pretty much everything i can pre design in inkscape i finally started working on it a few weeks ago. Ill update here as i work on stuff. Pure Sloper but with some LEDS in the back. This is something fpv wing guys have been doing for a while but i havent seen anybody sloping with cool leds yet.


To deal with the extreme sweep of the center section i "buried" it inside a shape i could cut out and than cut it out of that shape. It doesnt match the airfoil of the connecting pieces, but i can hide this with some sanding and spackle later.


I needed some way to attach the vertical fins in back and wanted some kind of "jet booster" kind of thing to hold some automobile led break lights. Still playing around with the size and shape. But this will allow me to attach the fins with nylon screws into the wood.


Went back and forth looking at spar options. In the end i decided on an I-beam of 2mm fiberglass kite rods with some carbon fiber rods here and there. Fortunately i remembered to put in the servo and led light wiring i needed before gluing them in.

Airfoil used is Peter Wicks Pw51, this is pretty much the only airfoil i use for flyingwings/planks for slope soaring.
For covering i will be using waterdown elmers glue and 60 pound brown paper, pretty much what i did on my 1/7th scale f-100.
gorilla glue for most stuff, hot glue to stick the spars into the Rigid brand foam, low temp.

Really wanted some led lit up laser guns on the wingtips but they are so thin i am not confident they will stay on. Not much meat out there to glue anything or attach anything. So will just be some hella bright break light "jets" and super bright white spotlight in the nose.

For graphics it will be a X-wing inspired paint job

decided to mount the fuselage access on the bottom of the plane. I need a good size area for a 3s 1000mah battery to power the lights. This box will also help strengthen up the foam in the nose. Plus this flat bottom lid will be much easier to make than trying to do something on top with all those curves.

So... I watched the most recent FT podcast today, and they're moving to hotwire manufacturing, and plan to start carrying supplies for hotwire scratch builds.

You were leading the curve with this project! ;)
2016 me with fishing wire and a 3s battery doing it by hand. I had been watching Andrew newton for a while and he did this a lot. Been trying to get flitetest peeps into it since than. Not sure exactly what they plan to do with it but excited to see if they can get epp and other materials shipped for a reasonable price. There has always been people that sell epp for hobbiest but its almost as expensive as just buying a fpv wing kit from sweepwings, vas, or defiantwings.

I have commented a few times on the hotwire pics around social media the past month but nobody responds. oh well back to my own thing lol.
