The UDI i250 Evolution
is UDI’s first foray into the
world of collective pitch helicopters
and just as you would expect it really excels!
With 3 different flight modes it can change
from hovering to flying around and even 3D
with power to really impress thanks to the
brushless power system. The helicopter
itself is made from a combination of metal
and precision moulded plastic optimised
for strength without excess weight.
Instead of a complicated tail belt or
drive shaft and pitch mechanism the
i250 has a tail mounted gearbox
to keep things simple and easy
to repair. The i250 is a perfect
first step up into collective
pitch helicopters. and has the
performance required to progress skills right up
to 3D flight! Supplied RTF (Ready to Fly) from the box all of
the electronics are pre-installed for you. To get in the air all you
need to do is charge the included 3S 1000mAh Li-Po using the included
balance charger and put 4 x ‘AA’ batteries (not included) in the transmitter!
Fully 3D Capable
