DISCLAIMER! DUE TO COVID I HAVE BEEN UNABLE TO GET OUT AND FLY THIS MODEL AEROPLANE, HENCE THERE IS NO FLYING VIDEO. See blog post for more details.
This is the legendary X-29 designed by Grumman and built by NASA. Our 3D printed version has a 1m wing span and is 1.5m long, using either a 64mm, 70mm or 80mm EDF. We HIGHLY recommend it be printed in LW-PLA to achieve a flying weight of around 1000g.
