Yak54 EPP

Before operating this unit, please read these instructions completely.

Features:

EPP-YAK54  is  super  aerobatic  model  for  3D  aerobatic  flying. 
Model  is  produced  by  modern  technology  on  CNC  machines 
from EPP “almost unbreakable” material. 
The  flying  time  of  EPP-YAK54  is  between  8  to  15  minutes,  it 
depends  on  the  flying  figures.  The  model  is  able  to  “torque 
roll”and then after giving more “gas” to rise verticaly up, looping 
in  “knife”  flight  and  all  aerobatic  figures.  It  is  very  easy  to  land
