FLYING
 |
|
Pick
a reasonably calm day for the initial flights. Gently
launch the model straight ahead and check the control
responses. Once satisfied, keep increasing the intensity
of your hand launches and you will be able to climb more
steeply. As the glider approaches the top of the launch,
get ready to feed in a little bit of down elevator,
otherwise it will run out of airspeed and the glider will
stall. |
I made a
simple, lightweight bungee using 30m of 5mm commercially
available bungee cord and 100m of 25 lb fishing line. It works
really well with the Blue Wren, and it's no problem to get 300
foot launches. I've also been experimenting with a device
similar to the woomera that the aborigines use to launch their
spears. It's just a short length of broom handle with a ring on
one end and a small U-shaped bracket lined with felt in which
the glider fuselage sits. The ring hooks onto the glider's tow
hook, and "whoosh", away she goes. I've had some good
launches using this device.
The Blue
Wren is a very stable, predictable glider that is a pleasure to
fly. It will stay airborne on a very small bubble of rising air,
will turn effortlessly on a wing tip, and will manoeuvre like a
bird.
Have a
go; put one together. It won't cost much to build, and you will
have a lot of fun flying it.
