2)  Ball bearing wing hinge assembly: 
 
 The hinge bearing plates are installed on the fuselage with the bearings already installed in 
 them.   
The wing spars are attached simply by slipping them between bearing plates on each side and 
screwing in the supplied #5-40 X 3/4" socket head cap screws.  Screw the cap screws in from  
the front of the bird and apply BLUE Loctite to screw at the center hole at the end of the  
aluminum spar ferrule and screw the bolt in and out slightly to disperse the Loc-tite.  This is  
done to avoid getting Loc-tite in the ball bearings which may damage them.  Tighten the cap  
screws down tightly against the front of the bearing plates.  Tighten down gently and the 
check and make sure there is no binding.  The spars should move freely at the hinge.  Let the 
Loc-tite set up once adjusted.    
 
 
3) Fasten the wingsail 
 
Now notice there are 3 slots in the center Dacron strip running down the center of the wingsail. 
 
Slip these slots down over the corresponding posts on the top of the fuselage.  
The wingsail is held in place with small included O-rings ( in the main parts bag) which snap 
down onto the fuselage posts. 
 
Once you have the wingsail slipped onto the posts, now snap the diagonal batten ball link 
housings onto the metal balls at the rear root of the fuselage.  Check that the wing can freely  
 pivot up and down. 

 

Now get the loc-tite ready 

 

Shake the loc-tite well and apply a drop or two to the threaded aluminum spar ferrule holes  
and attach the large ball link connecting rods with the cap screws provided.  Depending 
 on the date of manufacture, your kit may have #4-40 cap screws, or 3mm cap screws. 
Whichever it has, the threaded ferrules holes will match the screws. 
Now back out the screws mounting the bottom of the connecting rods to the crankshaft, 
apply loc-tite and re-tighten.  Tighten all four screws tightly but within reason to avoid stripping 
the threads.  Allow the loc-tite to set up ( an hour or so). 
 

 This completes the wing assembly

12)  Battery Charging and Precautions: 

 
The new lithium polymer batteries offer even better power to weight and duration than NIMH 
batteries.  Li-poly's are the latest trend in electric R/C and will probably replace NIMH batteries 
in R/C applications altogether in the near future. 
Lithium batteries are extremely light for their energy output and storage.  They do not have the 
self discharge trait of NIMH batteries, not do they require cycling, however they are affected by 
cold temperatures.  Performance may suffer greatly as a result in temperatures below 50 
degrees F.
