Antenna installation 

The CFK-fuselage shields the  rc-radio. So it is indispensable to install the rx-antenne outside from the 
fuse! To do so you can drill a small hole into the fuse and glue an antenna tube or the antenna itself 
into the hole. 

Retrofitting and assembling of the rear mechanics 

Remove the rear fin. The two short screws hast o be replaced by M3x8. Thereby please use one flat 
washer outside and two between fin and tail gear. 
Assembling of the tail gear: fix the tail rotor control arm with cylinder head screw M3x24 and the rear 
fin with the aluminium bush with cylinder head screw M3x18. Please ensure that you fix both screws 
with thread lock and screw them firmly. 

Put on the front hood 

Pull the front hood similar to the original TDR front hood over the front area and over the wobble plate. 
Thereby it is helpfully when the wobble plate is completely at the bottom (complete negative pitch) and 
the linkage rod is behind and in front of the main shaft and not on the side.  
During the last centimeters you should first insert the lower bolt into the corresponding borehole of the 
fuselage  and  then  put  the  upper  end  of  the  hood  to  the  fuselage.  Finally  insert  the  upper  bolts. 
Through to the magnets the hood downright clicks onto the fuselage. 
 

It may happen that at an extremely pitch angle generate vibrations which can loosen the hood. 
Therefore I recommend to fix the hood on the upper side with a 3 cm long adhesive tape. 

 

Operation 

Its highly recommended to check the mounting screws after every flight. If they are tight after the first 
flights you can tape the mounting holes with the supplied round stickers. 

 

Since  the  fuselage  can  not  replace  the  tail  support  completely  please  avoid  hectically  maneuvers  in 
flight like pitch pumps. In extreme cases this could bend the tail boom which leads to an unbalanced 
running  torque  tube.  This  in  turn  causes  strong  vibrations  which  can  lead  up  to  destruction  of  the 
fuselage  in  the  air.  This  scenario  has  been  activated  during  the  test  phase  by  very  high  rpm  and 
extreme pitch pumps.
