E-FLITE UMX B- 25 MITCHELL BNF BASIC
The UMX B- 25 Mitchell BNF Basic
comes completely assembled, painted, and ready
to fly right out of the box. To complete the model,
you need a four-plus-channel transmitter with
Spektrum DSMX/DSM2 2. 4 GHz technology, a
300 to 500 mAh 1S 3.7-volt LiPo battery, and a LiPo
After taking the model out of the box, I was
impressed with its scalelike detail, including its
panel lines, scale guns, three-blade propellers,
and the airplane’s accurate-looking color. It even
includes a decal sheet that lets you choose any of
the 16 Doolittle Raiders airplanes to customize
your aircraft! I chose the markings that I liked and I
applied them using a small pair of tweezers.
I checked the B- 25 to make sure everything
looked okay. Although the airplane is ready to fly,
I checked the flight controls for
proper movement and direction. I had
to make one correction because the
rudders were slightly off center with
neutral rudder trim. I adjusted the
linkage using a pair of needle-nose pliers
and it was ready to go.
You can fly without the removable
landing gear to simulate retracted gear. I
normally fly off of grass, so I made most
of my flights with the gear off; however,
I needed to test the model with the gear
installed, so I took it out to a local flying
field with a beautiful paved runway. The
nose gear on the airplane is steerable, and
I found that while taxiing, the airplane
can turn a tight circle when needed.
My first flight was straightforward
and uneventful. A six-channel receiver
featuring AS3X technology is installed.
This gives the model a solid, smooth feel
in the air. It tracked well on the takeoff
roll. I took off, made a few circuits
and a few small trim adjustments, and
proceeded to test the aircraft’s stall
characteristics. With the AS3X system,
stalls were clean and easily recoverable.
I made a few slow, scalelike flybys.
The model really looks great flying low
and slow! I set up for landing, keeping
the nose high and touching down on the
main landing gear.
Yes, the airplane is a scale model of
a World War II bomber, but I couldn’t
resist doing some sport aerobatics with it.
The aircraft has a semisymmetrical wing
and good power, allowing it to easily
perform loops, rolls, and even inverted
