 that the V-Good 120A ESC is small 

and can temporarily pass back through the former temporarily for wire connection.



Use sandpaper to clean rough edges on the aft inlet duct. Clean-up the front and back edges to allow 

easier installation.



Remove the fans aft center body fairing and set aside. On the JP made fans this is a 

normal thread.

 

4.

 



Remove the fans front 

‘bell mouth’ if equipped an

d store it. (It is not used 

for the FlexJet’s full flow 

ducting). On the JP made fans the bell mouth is a 

reverse thread



Use some 

1/8” to 3/16” (4 to 5mm) wide

 automotive striping tape to make several turns around the 

front of the fan. Test fit to the duct till it fits close, but freely. It does not need to be tight. This feature 
prevents wear on the fiberglass duct and allows different fans to be fitted. 

NOTE:

 There is a NOTCH on the back portion of the fan mounting lug. This permits the tailpipe to slide 

over that outside of the fan shroud.
