Construction / tuning:

The simple box contained all part for this plane.
As it is made from styrofoam you need to be very careful when handling
the parts in your shop. Easily it gets dents and chips!
For the rc components I opted for some standard gear, however the
servos were all around metal geared.
The motor is a real treat - excellently manufactured brushless inrunner
(2 poles) recommended for max. 3-cell lipo operation on a ducted fan.
As per motor manual up to 1,2 kg of thrust is possible. We will
measure once the plane is completed.

The building was easy and I followed the (minimalistic) instructions -
with the following exceptions:

Fan: I did not buy the recommended standard fan, so some sanding
had to be done before the fan would fit nicely.

Aileron servos: the connection to the ruder horns is planned to go
through the wing to the upside - I connected them straight at the bottom
and will cover the connection with an ABS piece.

Canopy: I installed a grip for easier opening of the canopy (the
supplied magnets are really strong and grip the canopy hard).

Note: be sure that you check and double check the fuselage fitting
before you finally glue the halves together! Also double-check the
elevator servo that it is in neutral position before gluing the halves! You
will not be able to reach it afterwards (only with cutting through parts of
the fuselage).

Finally I applied a 2 k paint cover over the entire plane to strengthen the
surface and make it fit for "belly-landings"!
