Construction / tuning:

The box contains all parts to complete the plane incl. stock motors
(brushed 400 size, 6 volts) - all fits perfectly and following the detailed
instructions even beginners will not have a problem to build this plane
over a weekend.

I envisioned a multi-purpose plane rather and therefor I build additional
features:

- flaps to enable me to fly ultra slow (for on-board videos) ... but they are
not necessary for landing as the plane itself flies rather slow

- powerful motors (rather for power then speed) and therefor I choose
two stock sets (were on sale) that are actually designed for the
EasyCup (Multiplex, also a foam plane with 140 cm wingspan but
single motor). After small alterations to the motor mount (to enable the
outrunner to spin freely you need to clip away most of the screw
holders) and enlarging the cable shaft from the motors to the fuselage
all worked great. Power on 10x5 " props is more then enough and
plane can fly with 35 % of throttle straight. Flight current is around 7 A
which allows for 20 min flight time on the indicated battery pack! With a
5000 mA pack I already managed 35 min but I found the weight too
high!

- landing gear (steering nose wheele hooked to the rudder) and
twin-main wheels - all stock items from the local dealer on 3 mm steel
and 55 mm lightweight wheels.

- cargo bay: for fun and kids surprises (they love to search for dropped
candies.... :-)

- On board video equipment:  fly-cam-one2-eco (4 GB miniSD card,
hooked on free receiver channel) - of course removable!

- As you may note, I did not use the stock decals for windows etc, but I
painted all with Edding permanent marker pens. Also on the motór
mounts, but there the paint comes off by the time.

- the motor mounts I covered from the bottom with some Depron
pieces (for good looks only).

Flight Experience:

Just great. Sound is fascinating and the power is absolutely enough for
the additional weight. Even in strong winds this plane churns forward
like a bulldog without problems.
First flight lasted just over 15 minutes and I landed for fear of overusing
the lipo battery, but no worry, I had to load only 2100 mA and that was a
surprise.
Following flights until today without any problems. See the videos for
yourself.

Update: September 2011 - installation of a release mechanism

The idea came from my son to be able to launch one (or two) of his
throw planes from one of my rc-planes! OK, I thought and with a little
planning I installed two Hitec HS-55 servos in the wings (one on each
side) by carving out the foam so the servo fitted snug into the hole. Both
servos were fixed with two drops of hot glue.
Then the rod was inserted in a trench that I burned with a solder pen.
Rods were fixed with cyan glue.
And finally a steel rod was inserted to such a length that the servo was
pulling it back to release - whatever was hanging below the wing.

First flight with two Felix 45 kids throw planes happened mid
September at quite some stormy weather. Both planes released well -
however one flew away that far that we could not find it anymore (the
farmer will however sometimes in the future). The second ended up in
a high tree near the model-airport. With a ball we managed to get it
down after several trials.

Experiment was a real success as my kids claimed! Next will e a
couple of parachutes... we will see!
