Construction / tuning:

The construction or better said the assembly took just two hours (without
decoration).

As there was just a flimsy paper as a manual, I started building just like
that and you can not go wrong anyway.
The motor and servos were fixed (glued) with hot glue - all other points
were glued with Zacki (Multiplex Elapor foam glue).

As an ESC I used a Multicont with 37 A that I still had in the drawer. This is
on the lowest end possible, as the recommendation for this motor setup is
40 A +. Now lets see how this will go in real flight.
During test runs the motor on the prop as specified sucked 34 A - but
usually in-flight that should go down and moreover, I usually do not run all
time at full throttle.

Excellent I found the hard cover made from ABS plastic that you glue at the
underside of the fuselage in order to protect the planes belly. Multiplex
should offer this for all its Elapor gliders/planes that land on the fuselage
belly. So you could avoid the much heavier tape. Well I will recommend this
to MPX these days.


Flight Experience:

Early November 2010 brought the first flight. Great sunshine at 15 Celsius
and almost no wind were the conditions during that weekend.
With a strong throw approx. 30 degree upwards at full throttle I launched
the Micro Jet! With my experience with the Fun Jet I already anticipated that
the plane takes down its nose but recovers just before ground contact.
At full speed the plane is out of sight within 10 seconds.
It would be great to be able to measure the actual speed - but none of us
has a laser gun or telemetric devices (yet).

The power of the Turnigy motor surprised me - and it ran smooth and
virtually without vibrations!
When going at full speed the plane has a tendency slinger a bit and to turn
right, I guess this is because of the motor momentum, so I played a bit
with the angle of the motor - and good it was! However the slight slinger
did not go away, but this is not critical anyway.
A real little fun plane which is ready within 20 seconds for flight at the field
(just plug the battery).

But nothing for the beginner - its too fast and at full speed really itchy to fly.
I truly enjoy this plane.




Update: November 2010

During the 2nd flight - due
to pilot error - during a low
inverted pass over the field
.... well the wrong direction
of the stick was pulled and
the end was.... yes... a hole in the ground an a micro jet in pieces.....

Damage report:
Wing brocken, motor came off, fuselage broken, fuselage guard broken,
total plane "compressed", prop cut a hole in the 2nd wing, one aileron
hinge broken,.....

At home and 45 minutes later the puzzle was put together... "almost" as
new.....  














Lets see how the plane flies after this half bottle of cyan glue.... and funny
... the plane is almost a cm shorter (due to the high impact I guess).

Update - Yes, it still flies and NO changes in the flight pattern could be
detected! Great!
