8. Installation of motor 

 

To install motor back on glider

, follow the reverse order of previous chapter. 

Take care about additional steps:  

1.

 

Below M8 motor fixation bolts, it is recommended to use new brass safely spacers 
 

2.

 

Make sure that power cables are connected in the same order as before (check your 
photo for reference). If order is not correct motor might not run at all, it might run 
but not achieving proper RPM or it might run in wrong direction. Use only new M6 all 

metal locknuts. 

 

3.

 

Make sure that there is at least 3mm of air gap distance between cable shoes and 

mounting wall and between cable shoes and  M8 bolts. Lower left M8 bolt (below 
power cables) should have lower head. 

 

4.

 

Carefully plug in DB15 male connector into motor rear wall female connector. Secure 
connector on both sides with spring locks. 

 

 

After motor is reinstalled, check that: 

 

Spinner is nicely located in the middle of the fuselage when spinner is in stop position. 
This means that surface of the spinner is as much as possible tangent to the fuselage 
contour in area of gap between spinner and fuselage. 

  

 

Gap between spinner and fuselage should be 1mm. Gap should be equal all around 
(on top should be the same as on bottom side, on left side should be equal as on 
right side). 

 

 

All bolted connections are assembled correctly and secured properly. Below six M8 
bolts which hold motor in place are thin brass safety spacers, which ears needs to be 

bend 90 degrees against one of the 6 vertical surfaces of M8 hex head bolts. 

  

 

Start the motor on a ground and run it for a few seconds to check: 

 
-that  motor  rotating  direction  is  counterclockwise  (looking  in  front  of  the 

propeller), and that motor is running smoothly 

 
-that electronic braking of propeller works (above 1500 RPM) 

 
-FCU instrument is functioning properly (check about all functions of the FCU in 

its dedicated FCU manual)
