Secure using the four M5 nuts provided. Also note that you may have to enlarge the holes in the 
wings and fuselage to 5mm as during painting and transit, the diameter of these holes effectively 
shrinks. 

 

 

Step 9: Installing the EDF sheath 

Due  to  the  unusual  shape  of  the  EDF  housing,  I  suggest  installing  the  sheath  (internal  duct  to 
promote efficient airflow within the housing) before installing the EDF units. If you do not wish to 
install this sheath then skip this step. 
 
First start by cutting out the following template from the fiberglass sheet provided 

 

298mm 

260mm 

250mm 

Draw a border 15mm 
from one edge
