The kit
Wings were neatly packed in a strong box inside the larger box so
the kit is safely shipped. All parts are cut accurately by laser
and CNC machines. The covering is nicely applied but mine needed
tightening with an iron in places. All the hardware you need to build
the plane is included in this Almost Ready to Fly (ARF) airplane. The
supplied hardware is top quality heavy duty hardware that you don’t
see in kits on this category with exception to the fuel tube which I
replaced. The Bad Boy V-2 is a large 40 size profile plane, it has
removable wings joined with carbon fiber wing tube. The ARF includes
carbon fiber control horns for all the surfaces. Hinge slots for
all surfaces have been pre-cut. The fuselage construction conceals
servo wiring exiting at the wing root point. Precision Aerobatics have
taken the time and effort to produce an excellent ARF.
The build
The manual demonstrate clearly each step with many photos. Construction
began on the wings. The ailerons were hinged with cyanoacrylate
(CA) hinges located in the pre cut slots. A couple of drops of CA glue
was added to each hinge on both sides. Next came installation of the
carbon fiber control horns in the ailerons. The control horns have the
carbon fiber awesome woven texture and are made by CNC. The
installation consisted of milling a small slot in the necessary place
and epoxing the horn in place. The ARF comes with extremely strong and
lightweight carbon fiber push rods and the necessary items (Extra large
metal clevis and HD metal coupler) to make up your HD push rods. I
measured the length from the servo output arm and surface control horn
to get the necessary length of my push rods. The carbon fiber rods
and the metal clevises were put together and hooked up to the servo and
surface.
The wings were attached to the main fuse with the carbon fiber
wing tube and three bolts and nuts pinched up, at this point a check has
to be made as to how the wing sits on the fuselage if a gap is evident
then it is necessary to shim the root with the provided balsa shims
glued and sanded to suit. Next came the installation of the rudder and
elevator servos, again, the servos are located in the tail end of the
fuse and the servo wires pulled through the fuse. Threading the
servo leads through the fuse body was a piece of cake with the
preinstalled draw strings. Once that was done, the Vertical stab was
installed and checked to make sure it was perpendicular to the wings.
After installation of vertical stab came installation of the horizontal
stab. I then hinged the rudder and elevator. Installing the carbon
fiber horns in the surfaces was exactly like the ones on the ailerons
and the construction of the control rods were the same as the ailerons.
The CNC aluminium landing gear was used, I’ve been advised that
Precision Aerobatics now offers carbon fiber landing gear and CF wheel
pants as well as fiberglass. The CF tail wheel assembly is also easily
installed (boy they like carbon…) You Just bend the wire to the
necessary length and bolt it on the bottom of the fuse. After
mounting the wheels, I decided not to install the wheel pants on the
plane.
Carbon fiber
Precision Aerobatics say about this kit (as well as some other kits of
their design like the Katana mini 3D electric), which I also have and
will review “Carbon fiber everywhere!” I couldn’t agree more:
Other than the wing tube and wing sleeves, the leading edge of the wing
is also made of Carbon Fiber. You get Carbon fiber CNC machined control
horns and CF tail assembly mounting plate, CF pushrods and CF servo arms
are an upgrade option and are not include in the kit. The CF arms will
allow for maximum throw. More than 45 degrees. getting 50
degrees of throw on the ailerons and elevator is possible, but I set
mine to 45 degrees. These arms will give you all the 3D throw you
need and can be tamed down for pattern flying.
Radio set up
JR 9X2 radio was used for this ARF. Programming was accomplished
in a short time due to my familiarity of with this radio. 15
degrees of throw for the ailerons and elevator for low rate was
programmed in the radio and 45 degrees for high rate ailerons and
elevator was programmed. For the rudder I programmed in as much
throw as I could get and cut that in half for low rates. Next came
Expo. 40% expo on everything for low rates except the rudder was
added. I put in 50% expo on low rate rudder and 70% expo on high
rate rudder.
Flying.
