YEAH!

It flies and it flies great !

Started with some up elevator on the launch, seemed to be a bit too much.

During normal flight the up elevator I planned, seemed also too much, flies almost straight without up elevator. Just as Ironeagle predicted.

When powering, the plane tends to lift its nose.
Planning to mix the throttle with some down elevator.

Looking forward to tuning this wing !

This is why we build, for the kick of the maiden !

ZDelta ready.
So ready to start a new design.

Alternative to the FZX design, this one has duct inlet on top.
This makes it possible to install a retract in the belly.

Early design attempt .., wings later, once COG of fuselage is estimated

Woodwork finished.

Added landing skids to the tips, otherwise the whole wing bottom would be scratched during landing.

Now the most difficult step: choosing a color pattern

Horns remade to have more power: extended them from 13 to 22mm height above hinge line.

Also BEC increased from 5.25 to 6 volt.

Both changes result in overall 93% more torque.

Made the nose cone smaller to accomodate a 30mm Spinner.
Looks better and reduces drag.

After a lot of preparation, i finally managed to glue the third sheet.
I must admit, this turned out to be not an easy task ... never glued such a large balsa sheet in one pass.

Turned out fine. You cannot even see the line between the two sheets.

TE not glued yet.
