Each main L/G door (left) is controlled by a Futaba BLS175SV servo (right)The wings are supplied ready to install servos and L/GThe one piece tailplane is secured in place by two
frontal pins and two screws at the rearThe fin/rudder assembly is removeable, and has a nice
robust carbon rod and an aluminium anti-rotation pinand I never, ever, ever had to send one back to repair or even had
any minor problems! Never! So my choice had to be the Evojet
180EX. I know that even a 180 is too much for this model, but I’m
a passionate believer of the art of throttle management: I like to fly
at around half, or even less throttle, to keep the speed to scale for
the subject I’m flying, and thus have plenty of power to perform
vertical manoeuvres with the precision required for high level com-
petitions such as Top Gun.
We installed the composite 4 Litre tank included with the kit (which
we had washed carefully as per Dave Wilshere’s recommenda-
tions in the first article of “Starting with Turbines” published in our
August/September 2017 issue), and we added the fantastic com-
posite UAT made by Osvy Model. To keep the weight to a mini-
mum, especially in the rear of the plane, I decided to install a cus-
tom thrust tube made by the same company; Osvaldo Gotta,
owner of Osvy Model, made a real piece of art: the main tube is
titanium, the outer tube is produced in light aluminium, and the
bellmouth is in hi-temperature carbon! The final weight is a mere
277 gram (0.61 Lb)! Let me tell you that Osvaldo is a real genius
with composite materials and metals, and he’s great at makingL39_Layout 1 08/03/18 10.13 Pagina 4
