Introducing FlightLineRC, the new brand from Freewing Models! FlightLineRC will bring you a
new series of propeller driven aircraft at the same level of quality and value you trust
from Freewing. Flightline brings to you the outstanding innovation, exquisite design, high quality,
unbeatable value, and dependable performance you come to expect from Freewing. Thank you for
purchasing the FlightLineRC 1200mm Spitfire Mk. IXc!
Overview:
The Supermarine Spitfire is one of the most popular warbirds in history. This British single-
seat fighter was used by the Royal Air Force and the Allies, earning distinction during the
Battle of Britain and throughout World War II. Over 20,300 aircraft were produced with more than
24 variants. The Spitfire's versatility and maneuverability made it a lethal aircraft against Axis forces,
such as the Focke Wulf FW-190. The Spitfire continues to fly in modern times as a tribute to
aviation history and military veterans.
Features:
FlightLineRC's Spitfire is the popular Mk. IXc variant. Over 5,000 of this variant were built
in World War II. The classic Spitfire colors are factory painted and included with the kit are two
decal sets so you can choose which scheme you want to install on your Spitfire. The first decal set
is for MK392, flown by the RAF Ace, James Edgar “Johnnie” Johnson in August 1944. The
second decal set is for MJ586, flown by the French Ace, Pierre Clostermann in October 1943.
This Spitfire Mk. IXc is approximately 1/9.5 scale, with a 1200mm wingspan. Molded
from EPO foam, the main wing and horizontal tail are attached with screws, allowing these
parts to be easily removed for transport. Only a few parts require glue and assembly is less
than one hour! The battery bay is large and uses a magnetic hatch to close it securely.
Servos are easily accessible for maintenance or replacement and proper
ventilation has been designed to keep the electronics cool. The electronic retracts
use metal reinforcement plates and the split flaps, plastic parts, and surface details give
your Spitfire lots of scale realism.
Power System:
The stock PNP version is equipped with a 3748-580KV brushless outrunner motor and scale 4-
blade propeller. With the recommended 4s 14.8v 4000mAh lipo battery, the Spitfire Mk. IXc is very
agile and has a level top speed of 135kph / 83mph. An optional “High Power Upgrade Set” can be
purchased separately to obtain a level top speed of 150kph/93mph. This Upgrade Set includes one
3648-880KV motor, a 12x8 2-blade propeller, and a 2-blade spinner.
( Conversion kit is sold separately, please contact MotionRC.com)
1. This is not a toy! Operators should have some basic experience. Beginners should operate only under the guidance of a

Installing Plastic Hinges
The control surfaces of this airplane use a no-hinge connection design. Although proven reliable, these type of hinges can be damaged due to
errors, causing the control surface to become loose or separate. Included with this kit is a set of plastic hinges if you wish to use them as an
alternate or for repair.
Step one
Use a knife to remove
the control surface
Step two
As shown in the diagram, choose
three attachment points, apply
glue to the long end of hinge, and
insert them into the three points.
Step three
As shown in the diagram,
apply glue to the other end of
the hinge and attach it to the
control surface.

According to our test results, the following rates proved to be a good starting point. Low rates are good for initial
flights or less experienced pilots. Adjust rates to suit you own style.

Build Notes
Hey guys!
I've taken the time to check out both the build video and the Flight Video by Ryan
Ramsay of Motion R/C as well as go through the posts on Hobby Squawk to try to
gather any build/ flight tips that may help you get through both successfully, with a
minimum of trouble.
First off, most people, including Ryan are using the recommended factory CG and
seem to be happy with it. The go to battery would seem to fall between 3600 and 4000
positioned all the way forward. When using a different battery, always check the
airplane out on a CG machine to ensure that the CG hasn't changed. Also, ensure that
your control surfaces are neutral. Being off even a bit will cause the plane to pitch or
roll.
When building the airplane, it is recommended that you skip steps one and two until
the wing is secured to the fuselage. Also, bind the receiver to the radio and set your
rudder and elevator neutral positions before installing the wing. It has been noted on
Hobby Squawk that the radiators and guns are side specific, so ensure that you have
the correct gun and radiator for the correct side before gluing. It's also recommended
that you use 30% expo for the first flight and then adjust to your personal taste.
For the build video, go to:
https://www.youtube.com/watch?v=FwdesiWtOSU&feature=youtu.be
and check out Hobby Squawk for the latest updates.
Happy Landings!
