Warning
This RC aircraft is not a toy!
If misused, it can cause serious 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 compromise between Aerobatics and 3D 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
h i gh
speed s
, because this may cause structural
failures or flutter due to the extremely large control surfaces.
Before st a rting assembly
Before starting the assembly of your Mytho S 50E, remove each part from its bag and protection
for a prior inspection. Closely inspect the fuselage, wing panels, rudder, and stabilizer for damage. If
you find any damage or missing parts, contact the place of purchase.
If you find 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.

Control throws
Please, follow the recommended linkage setups:
For the AILERONS we recommend the following throws:
High rate: 40° left & right
Normal flight: D/R: 30% Expo: 20%
Snap: D/R: 100% Expo: 90%
Spin & 3D: D/R: 100% Expo: 90%
For the ELEVATOR we recommend the following throws:
High rate: 40° up & down
Normal flight: D/R: 30% Expo: 30%
Snap: D/R: 40% Expo: 50%
Spin & 3D: D/R: 100% Expo: 95%
For the RUDDER we recommend the following throws:
High rate: 40° left & right
Normal flight: D/R: 40% Expo: 60%
Snap: D/R: 50% Expo: 70%
Spin & 3D: D/R: 100% Expo: 90%
Note: the Expo is (+) for JR systems, and (–) for Futaba systems.
Mixing
For best performance, we recommend a linear-mix*:
Rudder → Elevator UP
When you give full rudder to the right or left side, the elevator have to go up (positive) approx. 2%
* if you have a programmable computer radio.
Recomme n ded CG
The recommended Center of Gravity location is 165mm behind the leading edge of the wing
against the fuselage.
155mm is good for windy condition.
175mm is good for no wind condition.
You can use the battery pack, moving it forward or backward, to achieve the correct balance.
Range test your radio
Before fly, be sure to range check your radio as manufacturer’s instruction manual of you
radio-system recommend.
Double-check all controls (aileron, elevator, rudder and throttle) move in the correct
direction.
Be sure that your batteries are fully charged, as per the instructions included with your
batteries and that your radio is fully charged as per its instructions.
...good
flights!
