Flying with flaps feels di;erent in flight no matter which type you
have: plain, split, slotted, or Fowler. When engaged, flaps e;ectively
change the camber of a wing. ;is, in turn, will increase lift and
increase drag, and leads to lower stall and landing speeds. All good,
right? Well, sometimes that extra lift may include a pitch change as
an unexpected ride-along, and compensation may be needed.
■ Don’t experiment with your new beauty on its test flight.
■ After the proper flight trimming is done and with a fresh flight
pack, take the plane back up. Way up. Once you’re “two mistakes”
high, lower the flaps and observe the aircraft.
Giant scale is not just for the rich/retired trailer-toting gents anymore! This 84-
inch airplane fits in a sedan and has plenty of power and ability to turn heads at
the field, at the lake, or in the snowpack. Mild, scale-type flight can be achieved
with 4-cell batteries, but the plane can be powered with 5- or 6-cell packs for
more spirited flying. ;
size of the plane and the stabilization functions
and you get unbelievable stability in flight. ;e
manual’s center of gravity recommendation is
perfect. While on the tarmac, this giant plane
is right at home with excellent ground handling
and no bad tendencies.
Tracking: Trimming was almost unnecessary;
I think the test flight required three clicks
for straight and level flight. As often stated,
the wind hardly has an e;ect on flight
performance with planes equipped with AS3X
Aerobatics: ;ere is more than enough power
to accomplish a wide variety of aerobatic
maneuvers. For some, chandelles and lazy-8s
will fill the bill. More-aggressive pilots will
search and find that knife-edge flight, rolling
circles, and spins are well within the plane’s
bag of tricks.
Glide and stall performance: Remember that
even though it feels light in flight, the Cessna
150 weighs almost 10 pounds. ;at said, the
model will fly at very slow speeds and feels
quite solid before it finally breaks. Glides are
fairly shallow and comfortable, to say the least.
Whether you’re an intermediate pilot or a
hardcore stick banger, E-flite’s Cessna 150 is
ready to go. It handles wind well and can do
myriad maneuvers from mild to wild. If you
happen to bang it up, replacement parts are
Spektrum DX18G2 (spektrumrc.
com); Spektrum AR636 receiver; four
E-flite 26g digital servos; two 13g
digital servos (installed)
E-flite BL50 525Kv and 60-amp
Pro speed control (installed)
E-flite 15x7 electric (included)
E-flite 6S 5000mAh 30C LiPo
■ If a pitch change occurs—and they do—the pilot may have to respond
quickly with some elevator input. Do what is necessary to maintain
positive control, and remember that you can always raise the flaps and
resume flying as usual. When ready, land the airplane.
■ Note the amount of elevator you added in flight. You can create a
flap-to-elevator mix in your radio, which will add in a specified amount of
elevator input for you when flaps are deployed.
■ Finding the sweet spot takes a few flights, so be patient and adjust
it to your liking. Of course, if you are a Spektrum transmitter user, you
could always download the Carbon-Z Cessna 150 file to your SD card and
upload it into your radio to eliminate any of the guesswork.
