Brief History
First designed in 1953, the MiG-21 is widely renowned as a classic Cold War era brute and holds the distinction
of being the most produced supersonic jet fighter in the world. More than 11,000 MiG-21s of different variations
have flown for over 60 countries over a period of more than 60 years. In fact, the unmistakable outline of the MiG-
21 can still be seen today in the skies of over 15 countries that still operate this historic warplane. The MiG-21 has
earned its place in aviation history as a versatile workhorse and venerable foe.
Overview
Dominate the skies with Freewing’s 1/9 scale MiG-21! Its impressive 1730mm length makes this MiG-21 one of
Freewing’s longest model aircraft. Its removable wings, horizontal stabilizer, and vertical stabilizer make transport
very easy. Even the nose cone and pitot tube are removable! Freewing has recreated many scale details of the
MiG-21 “MF” variant, and the aircraft is powered by an 80mm 12-blade EDF and an all-new 3530-1800KV out-
runner motor and 100A ESC. Newly designed metal gear digital servos control the ailerons, flaps, elevators, and
rudder, and an integrated circuit board simplifies wiring in the large battery bay. Magnetic fuel tanks and the iconic
“blisters” throughout the fuselage help complete the look and feel of the menacing MiG-21. Although an 80mm
class aircraft, the Freewing MiG-21 features the retractable landing gear of a 90mm class aircraft. Durable
aluminum trailing link struts and tall wheels allow operation on short grass fields.
Flight Features
The Freewing MiG-21 is suitable for intermediate and advanced pilots with EDF flying experience. The model’s
strong thrust and flaps shortens the takeoff distance to 30 meters. Optimized design allows the Freewing MiG-21
to fly stably at both fast and slow speeds. In fact, the aircraft can maintain a slow “high alpha” attitude of up to 40
degrees without stalling. The delta wing and swept tail give the aircraft crisp responsiveness but gentle handling.
Also, the battery bay was designed to accommodate an optional Freewing Gyro E51, sold separately, to further
supplement the stable flying characteristics of the Freewing MiG-21. Experience the thrill of a 40 degree pass with
ease!
Color Scheme Introduction
Freewing presents its MiG-21 in two color schemes. The classic “Soviet Silver” scheme includes decals from
four countries inside the box to allow pilots to customize their model aircraft. A “High Vis” scheme is also available
that features the blue/white/grey color scheme of the MiG-21-93 variant for increased visibility in the sky.

Traction steel wire use instruction
Through investigation, excessive servo extension line will increase the risk of poor contact joints, and lead to the
servo outages caused flight accidents. Because of MIG-21 large and flat trough interior space, we don't use the
servo extension wire in this jet. As the below photo shown, package includes a traction steel wire, we can use it to
pull the main wing/elevator/rudder servo cables to the battery compartment.
Prepare work before install
1.Open the cockpit, loosen the screws which fixed on the battery
tray, and remove the battery tray. 2.Remove the intake plate.

Center of Gravity
Correct center of gravity is directly related to the success of the flight, please refer to the following CG diagram to
adjust your plane's center of gravity.
- You can move the battery forward or backward
to adjust the center of gravity.
- If you can not adjust the CG through move the
battery, you can also use some other suitable
material weight to counterweight, to make sure
that CG is in the correct position.
If you need to purchase other brand servo, please
refer to the following list to choose correct size

历史简介
1953年开始设计的MIG-21，是60年代前苏联空军主力制空战斗机。此机是第二次世界大战后，生产数量最多的超音
速喷气式战斗机，总产量超过6000架（不包括中国引进改型的歼7系列战斗机），在全世界，约50个国家和地区使用过该
款战斗机。
模型概述
飞翼1/9比例MIG-21MF，机长1730mm，翼展800mm，这款模型的外形线条及轮廓，完全依据真实飞机按比例缩
小制作，细节的处理，使外形更加逼真。大量使用塑料零件，使我们可以快速、便捷安装主翼、平尾及垂尾。较长的空速
管和机鼻，可重复拆解，防止运输过程造成损坏。MIG-21MF模型，采用12叶80mm金属外框涵道风扇，3553-1720外
转无刷马达，100A ESC。全机采用了8个9g金属数字分别控制垂尾、方向舵、升降舵、副翼和襟翼，新型集线盒的使用，
不仅使设备舱更加整洁，而且能够有效减少内置连接线，降低飞行时接触不良导致事故的风险。更大型号的涡杆控制器和
全金属避震起落架，更加牢固、可靠。
新 的 80mm外转动力系统，在高性价比的基础上，给MIG-21MF模型带来强悍的动力，最高时速达到
160kph/100mph。 虽然MIG-21的机体内
部空间非常难以设计，但是经过优化的电池舱空间，在保证重心的前提下，可以使用6S 4000mAh ~ 6S 5200mAh电池，
达到5分钟的最高飞行时长。
飞行特性
飞翼Mig-21MF电动涵道模型，非常适合中、高级涵道玩家，是一款非常富有操作乐趣的产品。强劲的动力，使得模
型最少起飞距离缩短到30M。经过气动优化设计的MIG-21MF模型，在高速和低速二种飞行状态下，均能保持非常稳定的
飞行，动作指令响应迅速，易于控制和保持。三角翼主翼及后掠水平尾翼设计，使得它具有非常优秀的爬升速度。低速大
仰角动作易于实现、不易失速。降落时，开启襟翼后，减速明显，姿态不会出现过大的变化，机体呈18~45度仰角，配合
油门，慢速、轻柔降落。
涂装介绍
我们为这款产品准备了二个涂装：蓝白灰色和银色。其中，银色涂装的包装盒内，分别包含了四个国家的战斗涂装贴
纸，可供选择。
（注：搭配飞翼模型80mm内转动力组最高时速达到180kph/113mph，此动力组，可联系经销商选购！）
同样地，飞翼模型的E51三轴增稳陀螺仪，可以完美的使用于MIG-21MF，我们为这个电子配件预留了安装位置，您可以参考说明书，自行安装！MIG-21MF模型，
在陀螺仪的帮助下，飞行将变得更加容易控制，可以更轻松的实现相关飞行动作！

机 身 组 装
1.使用胶水粘合前、后段机体
通过调查，过多的舵机延长线会加大连接处接触不良的风险，严重时，导致飞行过程，舵机断电而造成飞行事故。由于MIG-21内部线
槽空间大且平直，故此模型的机体内，未使用舵机延长线。如下图所示，包装盒内包含一根牵引钢丝，PNP配置下，我们可以利用这根
牵引钢丝，顺利的将主翼、平尾、垂尾舵机线布置到电池舱内。
