Exceed F-22 70mm EDF Review
The Exceed F-22 70mm EDF comes in 2 versions, the RTF and the ARF Kit.
I build the Airplane up from the KIT using existing
components I
already had along with purchasing an EDF motor from the F-18 spare
parts list. The ARF kit will come with the Fan assembly but no Motor,
ESC, Servos, Tx or Rx. The RTF kit will come with everything you need
to get up and flying including a battery. Please view the
specifics of each kit to verify it has what you will need to fly. The
Kit was very well packaged in a styrofoam molded box. The box
protects the aircraft very well. I build up the kit using 15
minute epoxy and installed the electronics (Tower Pro 90 servos).
The battery I had was a 20C 2200mAh 4S which is the
recommended
battery to use. However, if you purchase this kit or any EDF,
I
recommend you to spend a little more and purchase a 25C or 30C battery.
The extra UMPH you get will come in handy on power ups, take offs and
those times you need the extra thrust. Generally, EDF
aircraft
are designed for speed and unlike propellar driven aircraft, do not
accelerate quickly. For this reason, EDF jets are NOT recommended for
beginner pilots. This plane is designed to take off and land on a hard
surface. I do not recommend you fly off of grass unless it is VERY
short and you upgrade the front wheel to a larger one. I was able to
take off from grass only in the middle of August when our flying field
is almost full of dead grass. This plane does not hand launch well as
there is not a small enough surface to hold onto with your hand.
If you must hand launch, Nitroplanes has a smaller F-16 that
is
designed for hand launch only. If you don't like the American Flag
scheme, the plane comes in a few different varieties of coloring
schemes.
Setup:
The
Rx Ready and RTF version comes with 2 different brands of elevator
servos that are connected with a Y cable for use with Channel 2.
If you use all the same servos, you MUST have a 5+ channel
receiver and a transmitter that can mix in the 2nd servo channel to be
OPPOSITE the CH 2. Use the recommended throws from the
instruction sheet and add some exponential if you can to soften up the
control response. The airplane can do fast rolls and tight loops but if
you put too much elevator, you can stall the aircraft in a loop and it
will twist on you. Although the instructions say to glue the
cockpit on, you can design in your own method of making it removable
(glue in some wood blocks to screw the canopy down for instance) so
that you can access the nose wheel servo and make any adjustments
needed. I also added in some velcro to hold the battery in
place
in case the battery hatch came undone in flight (which it never has to
date). Before your first take off, make some practice runs
with
the nose wheel to get it straight. Set your CG EXACTLY per
the
manual (I needed to make no adjustments with the 2200mAh 4S 20C
battery).
ARF vs. RTF vs. Reciever
Ready
The
RTF kits will typically have servos pre-installed and the ESC will have
the correct wire lengths and save you lots of build time. If
you
total your plane in the crash, look to purchase an ARF kit and use your
existing electronics. The Reciever ready kits will have everything you
need excep the Tx, Rx, charger.
Battery recommendation : 30C or 20C 4S 2200mAh BlueLipo
