Here’s the build details and some video of my first flying wing built with the hot wire CNC machine.  I’ve called YMF-38 as its 38 inch wing span.  It uses MH-42 airfoil sections and uses a 2200KV brushless motor with a 6×4 prop.  A 2200mAH Lipo give about 8-10 minutes flying.  It flies really well and is quite fast.  I used XPS foam with 9gram servo’s.

The wing was designed in Profili Pro 2 which creates the g-code I then load into to Mach 3

My carriage distance is 32″ and the root of the wing is set at 6″ from the carriage.  The two downloads below are the actual gcode you send to the hot wire cnc machine.


Here are the dimension.  Center of Gravity is 6 1/4″ from the nose.  The end plates are 6mm depron which you can be any design you like.


Here’s the setting from Profili2 Pro

Here’s the placement of of the 3mm carbon rods.  I use a Dremmel with tile attachment to cut a slot and filled them with lightweight filler.  I then covered it in iron on Solar film.  The battery is secured with velcro and a velcro strap that goes through the wing.  Launch is very easy because on the underside there is a small grip which you can hold and apply about 3/4 throttle and she leaps away.

Here’s the finished YMF-38.  She flies extremely well and can really eat up the sky
