Another build (this time it flew first time)

Picked up a cheap HK 70mm Global Hawk ($40). Did a conversion from a edf to a twin boom pusher.

Flew really well on the first go.

Maiden Flight (3 min 13 sec)


I need to do better build report next time around.Cut tail off and glued in the edf mount reversed. Made boom sections using 3mm ply and balsa. Glued into a box, then drilled holes in each and injected polyfoam and let expand. They became nice and stiff. Measured wings and cut off for booms.

Epoxied the boom to the wing mounts. Cut grooves in bottom of wings to hold flat 3mm ply. Then glued 1.5 mm ply onto bottom of wing. and now the wings just slide through the booms.
tight fit so no need for screws(Yet)

Didn't like the control surfaces, way to flimsy. So replaced with balsa ones.
