F-15 is so popular a plane. Its aerodynamic outline, enables not only the original
wonderful performance, so is the duplicated model. In jet world,this plane is even
considered as a trainer by some modelers. Although JetLegend has already got a
1/10 scale one, F-15's features are not fully expressed due to its small size. When
it comes to the decision on size options, a 1/7 scale one is too big which would
use a turbine of at least P-180, while P-160 is more popular. With considering this,
a 1/8 scale one came out under this situation. F-15 original size is: Wingspan 13.5m,
length 19.43m. The model size is: wingspan 65in/1650mm, length 95in/2415mm.
With this size, the producer has more space to exert. It's firstly shown in the design
of the landing gear, as space is larger. A scale landing gear which is faithful to the
original became possible, especially the rotation function of the wheels after retracting.

Pic #1 Main wheel size for this 1/8 scale F-15 is 4.25in, nose wheel is 3.25in.
Wheel hubs and brakes are made by CNC, that guaranteed the likelihood to
Pic #2 Landing gear are installed in the fuselage with 4 pieces Ø3X10 hex
screws. Note,they are hex screws, instead of wood self-tapping screws. It
means saying goodbye to drilling holes in the wood. Just tap the hex screw,
it's finished. It's so convenient for users. And it won't happen again that the
gear mount wood is broken when landing. Assembling the metal components
is a easier job.

Main wing dowel is made of carbon tube ( see Pic #3 ), which is perfect in intensity
while light in weight. Work with the "U" mount plate (see Pic #4 ) in fuselage, it's
very easy for users to assemble/disassemble. Four mount plates like this are applied
in this model.
Same as the original, the main wing has aileron and flap. They are controlled respectively
by two servos. Servo size is standard size ( 40mmX36mmX20mm ), such as Hitec HS-945
MG, easy to fit in.( standard size servo with 10KG or above torque is recommended).
Note, parts in Pic #4 are in standard package too.

There are two aluminum rods for the rudder. They are also linked to the fuselage
with mount plate ( see Pic #8 ). It's also easy to assemble/disassemble like the wing.
For rudder servo, small size servo with 6 KG torque ( size 30mmX34mmX10mm )
is recommended, such as Hitec HS-5125 MG.
Horizontal Stabilizer Design:

Picture #15 Picture #16
In jet world, the design of horizontal stabilizer is always a key factor, especially
the control mechanism. Not only flexible movement, but also adequate intensity
is required. JetLegend's "One-Piece" design is fully satisfying this requirement.
Horizontal stabilizer mount plate ( Pic #13 ) has two ball bearing to support. Two
lock nuts lock the horizontal stabilizer tightly. At the meantime, a secure dowel
is applied in order to avoid it from being loose. Servo installation and the whole
control mechanism are "One-Piece". As long as the control mechanism is installed,
the whole horizontal stabilizer is installed. This design is greatly helpful to users.
Elevator servo needs a big torque. So standard size servo (40mmX36mmX20mm )
with 12KG or above torque is recommended.

The intakes are moveable. They are driven by servos. The function is realized
with one channel setup. Activeness of intake/elevator combined control and
elevator single control are interchanged by a switch on the transmitter. Intakes
are free to move like the original during flying and can be shut down with the
switch when it's not used.
Air brake design

Back hatch cover air brake, This is a usual design, but the cylinder control is
mostly like the original. The close end is connected to the open end with a steel
tube instead of air tube. This looks more like the original and easier to use.
