Product Description

Wing and Fuse cores to build a Nurf

This is the foam cores only.  You will need to source the kit parts as listed in the Requirements below.

The Nurf is an all EPP forward swept flying wing that is designed to be flexible enough to hold all your gear for aerial photos/video/FPV flight, and be tough enough to take serious abuse.  Tired of needing a catapult to launch your big wings?  Look no further.  The Nurf is easily hand launched.  The design is also flexible enough for landing gear, or even bungee launch if you prefer.  The Nurf can handle it all.

The Nurf is very stable in the air and has a great speed range.  We’ve even had it out in 25mph gusts and it handled it all well.  Please note:  The Nurf is not a trainer.  It’s close, but it’s optimized for better efficiency in cruise so enjoys maintaining energy.  It will slow down, but not as slow as a good trainer.  It goes where you point it, but will not return to straight and level without pilot input.  We think it’s a great second plane.  You’ve been warned.  Now order one and go have fun!
