Sebart 50E ARF
ASSEMBLY MANUAL
The new Sebart 50E ARF was designed by Italy aerobatic pilot,
Sebastiano Silvestri and it is a replica o a new ull-scale
aerobatic airplane.
This pro essional ARF kit is the result o Sebastiano’s long
research in 3D unlimited per ormances. This combined with an
extremely lightweight structure, the all wood air rame, the very
big control sur aces with special air oil and the li t generators
on landing gear give the Sebart 50E ARF an impressive thrust-
to-weight ratio and crisp control authority at any airspeed and
light condition.
This new 50 class model will enter you into the next level o
per ormace!
The Sebart 50E ARF can do it all…unbelievable easy harriers,
torque rolls, blenders, water alls and almost anything else you
can dream up are waiting you!
.....the only aerobatic limit is your fantasy!

Warning
This RC aircraft is not a toy!
If misused, it can cause serius bodily harm and damage to property.
Fly only in open areas, preferably in official flying sites, following all
instructions included with your radio and motor.
This plane is a compromie between Aerobatics and D flying, and not a pylon
racer.
It is built with a very light structure and for this reason we hardly recommend:
→ Do NOT fly your airplane at high speeds, because this may cause structural
failures or flutter due to the extremely large control surfaces.

Before starting assembly
Be ore starting the assembly, remove each part rom its bag and protection or a prior
inspection. Closely inspect the uselage, wing panels, rudder, and stabilizer or
damage. I you ind any damage or missing parts, contact the place o purchase.
I you ind any wrinkles in the covering, use a heat gun or covering iron to remove
them. Use caution while working around areas where the covering material overlap to
prevent separating the covers.

RADIO SET UP
Control throws
We recommend the use o a computer radio, that will allow you to do quite a bit o
ine-tuning o the eel o the Sukhoi, which will make aerobatics even easier.
For the AILERON we recommend the ollowing throws:
Low rate: 20° up / 20° down Expo: 40%
D rate: 45° up / 45° down Expo: 80%
For the ELEVATOR we recommend the ollowing throws:
Low rate: 20° up / 20° down Expo: 25%
D rate: 60° up / 60° down Expo: 80%
4

For the RUDDER we recommend the ollowing throws:
Low rate: 30° le t / 30° right Expo: 30%
D rate: 50° le t / 50° right Expo: 60%
Note: the Expo is (+) or JR systems, and (–) or Futaba systems.
Mixing
For best per ormance, we recommend a linear-mix*: Rudder  Elevator UP
When you give ull rudder to the right or le t side, the elevator have to go up
(positive) approx. 4%
* i you have a programmable computer radio.
Rates and expos
Use the recommended expos to so ten the eel o the model, especially on high 3D
rates. The goal is to get the model to eel the same around neutral as it does on low
rates.
Use low rate settings for all flying included starts and landings and high rate or
3D aerobatics.
For precision lying or general sport liers, the low rate throws are per ect, even or
snap rolls. When doing 3D aerobatics, lip to 3D rates just be ore the manover. As
soon as the manover is done, lip back down to low rate to avoid over-controlling the
model.
Recommended CG
The recommended Center o Gravity location is 150mm behind the
leading edge o the wing against the uselage.
Use the motor battery pack, moving it orward or backward, to achieve the correct
balance.
Pre-flight
Never attempt to make full throttle dives!
This model have to be lown like a ull-scale airplane. I the air rame goes too ast,
such as in a high throttle dive, it may ail.
Throttle management is absolutely necessary.

Range test your radio
Be ore ly, be sure to range check your radio as manu acturer’s instruction
manual o you radio-system recommend.
Double-check all controls (aileron, elevator, rudder and throttle) move in the
correct direction.
Be sure that your motor battery pack is ully charged, as per the instructions
included with your batteries and that your radio is ully charged as per its
instructions.
Finally... have nice flights!
