Horejsi Q12 X Manual

The EP glider Q12X is the competiton version of our successful Q12. It is supposed to be used as
competition-grade model for the class of "small outrunners", which is flown in many countries.
The rules include motor of 2826 size, minimum prop size 10", battery 2S, minimum weight 500
grams.
The foam/skin structure provides very high rigidity. The A/R can be very high. The ailerons and
brakes will not warp. The A/R is about same as that of free flight power models.
Each half of the wing is made as single part. The dihedral is built in during the molding
process.
The pod is very slick, yet it provides enough room for RC and power unit parts. The battery
must be lower than ca. 35 mm.
The rear fuselage part consists of carbon/glass boom. It provides rather long tail arm for
excellent flight stability.
The tail feathers are made in similar method as the wings. They are very lightweight.
The on-board RC system is supplied from the ESC BEC. Check if the BEC can supply receiver
and 6 servos. When in doubt, use Dualsky VR-3 voltage controller.
It can supplied from the battery balance connector.

Model assembly

Fuselage

Motor mount installation: Cut off the pod tip, so that the opening is of approximately 25 mm
diameter. The mount in the kit suits perfectly for the outrunners of 28 diameter o.d. and
spinner 32 mm o.d. The sizes of the mount and spinner allow for enough room for the motor
cables.
How to adjust correctly the motor mount: Find a longer bolt ca M8 with nut and screw on it
into the motor mount central hole. Use the bolt as the indicator of the correct motor axis
