Freewing 9801512 Albatros Yellow PNP 80mm 12B Jet EDF
Introduction
Combining the sport performance of the Avanti and the fidelity of scale aircraft like the A-4 and MiG-21, Freewing model continues the legacy of its excellent performing 80mm EDF jets with its Freewing 80mm L-39C/Z Albatros! Developed originally by Aero Vodochody in the 1960s in what is now the Czech Republic, the Aero L-39 Albatros excelled as a jet trainer platform with its powerful turbofan and overall reliability. The L-39 and its successive variants continues in service throughout the world in militaries as trainers and light attack platforms, and in civil aviation including aerial demo teams and racing.
The Freewing L-39 Albatros is the largest and most capable production PNP L-39 in the world. Optimized for high maneuverability and precision flying, the L-39 truly is a “Sport jet wearing Scale jet clothing”. The Standard Version uses a powerful 3530-1850kv brushless motor and 1 00A ESC to power the 12 blade 80mm EDF. A Deluxe Version upgrades the motor to a 3658-1857kv inrunner for higher power output.
The Freewing L-39 Albatros includes grass capable suspension landing gear, a full coverage nose door, scale wingtip lights, and easily removable tip tanks, ordnance, belly gun pod, and wings. Only one joint is required to complete the model’s general assembly. A plastic lined cockpit also resists deformation under sunlight, and optional 3D Printed cockpit detail upgrade parts are also sold separately.

Package list
Different equipment include different spareparts. Please refer to the following contents to check your spare part list.
PNP Install instruction
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 L-39 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.
Install horizontal tail
- Use 4 screw to fix the horizontal tail.
- Use traction steel wire to pull the horizontal tail servo wire to the battery compartment.
- A- Horizontal tail
- B-Screw (FA3x8mm 4pcs)
- C-Servo wire
Install vertical tail
- Use traction steel wire to pull the rudder servo wire to the battery compartment.
- Use 4 screw to fix the vertical tail.
- A- Vertical tail
- B- Screw (FA3x8mm 4pcs)
- C- Rudder servo wire
Install main wing
As the photo shown:
- Use Ribbon wire to insert the main wing control board
- lnstall the main wing at the bottom of fuselage, then use 4pcs screws to fix it.
- A- Main wing control board
- 8- Ribbon wire
- C- Main wing
- D- Screw (PM3X8mm 4PCS)
Install drop tank
Refer to the right photo, installed the LED light and drop tank.
- A- Screw (FA3X8mm 4PCS)
- B- LED light extension wire
- C-LED wire
Install small plastic parts
Pushrod instructions
Multifunction control box (MCB-E)
L-39 model plane use control board (Item No: E1712) to reduce connection wires, its more convenience to use the neat cl ear equipment compartment. For the specific functions and usage of control box, please refer to the manual of {Multifunction control box(MCB-E)
Battery Size
Before connecting the battery and receiver, please switch on the transmitter power and make sure The throttle stick is in the lowest position. Bind your receiver to your transmitter according to your hansmitter’s instruction manual.
We recommend the following Li Po battery:
65 22.2V 4000mAh ~ 65 22.2V 5000mAh(1 pcs)
Discharge rate of C ≥ 35C
Center of Gravity
Correct Center of Gravity ( CG”) is critical for enabling safe aircraft stability and responsive control. Please refer to the allowing CG diagram to adjust your aircraft’s Center of Gravity.
- Depending on the capacity and weight of your choosen flight batteries, move the battery forward or backward to adjust the Center of Gravity.
- If you cannot obtain the recommended CG by moving the battery to a suitable location, you can also install a counterweight to achieve correct CG. However, with the recommended battery size, a counterweight is not required. We recommend flying without unnecessary counterweight.
Control Setup Instructions
Control Direction Test
After installed the plane, before flying, we need a fully charged battery and
connect to the ESC, then use radio to test and check that every control
surface work properly.
Dual Rates
According to our testing experience, use the following parameters to set Aileron/Elevator Rate. Program your preferred Exponential % in your radio transmitter. We recommend using High Rate for the first flight, and switching to Low Rate if you desire a lower sensitivity. On successive flights, adjust the Rates and Expo to suit your preference.
Important Flight Notes:
A Flap-to-Elevator Mix is required to maintain level flight when the flaps are
deployed. The detail is as below:
- With high rate flaps deployed, mix 1.5mm of DOWN elevator.
- With low rate flaps deployed, mix 1.0mm of DOWN elevator.
