Prototype Biplane Delta Maiden Flight at Liak on 17.12.2016
thanks for the possibility to fly on your airfield at Liak as a guest and thanks for the support on site and all of our interesting discussions and communications during the last weekends at our flight events.
Here some facts and pictures of the developement of design and prototype of the biplane delta wing conzept of this year for you and friends.
Material:
electic wire installation tube 40 x 40 mm plastic, mounted doubled to get construction height 80mm for biplane configuration
depron 10mm (2 layers 5mm glued together) for the wings, rudders and winglets
tape
engine ca 400w 1050 rpm/v
prop size 12" x 6"
Lipo 3 s 2400mah
weight rtf incl. batterie approximately 2.5 kg
wingspan 1,00m biplane wing
aera of both wings ca. 1m2
fuselage length 1,50m
no profile (flat level)
center of gravity at the front edge of the lower wing
before mounting rc configuration 2 days tests as a free flight object at ca. 40 trials on ground handling.
after these tests ca. 25 trials with rc function aileron and elevon, but no powerplant activation.
then installation of a triangle rudder and winglets for better performance on longitudinal axis.
at 17.12.2016 3 flight tests as sailplane on ground handling thrown by hand and afterwards the maiden flight with support of the electric power plant, ca. 4 min
meanwhile 6 testflights plus at liak and vipava and the result is a very easy flyable and selfstabilizing biplane object with a wide spectrum of performance speed and the option to land as a sailplane modell nearly in "walking speed".
Enjoy it if you like.
If you have any questions about the object you can write me a mail or sms, I will respose asap.

Yes we were wondering, what is ESC doing in an electric cable support:
And the wing on that support cover:
Well, all together looks like:

Don't think that this thing doesn't fly: it flies surprisingly good
