Final Checks

 

 

Take a few minutes to re-check each servo to make sure all screws are in place and snug.  
If you use metal gear servos(a good idea), place one drop of thread locker on the screws 
that hold the arms on the servos.  Re-check all control horns, and all linkage for slop or 
looseness.  This would greatly increase the chance of flutter and could destroy your air-
plane.  This is a 3D/Aerobatic airplane with large surfaces.  Be careful to keep everything 
tight and control your speed when flying. 
 
Put on your prop and spinner.  Put in all radio and batteries.  Mount all switches & attach 
all wiring.  Assemble the airplane, we will now check the CG.

 

 
 

 
Once the cowl is ready to mount, 
slide it onto the fuselage and attach 
using 6-32 bolts and washers pro-
vided. Two screws go through the 
firewall into the cowl ring – two go 
through the ring into the firewall.  
Blind-nuts are already installed to re-
ceive them.  
 

Mark the root rib of each wing 6 ½” 
from the leading edge.  Transfer the 
mark to the underside of the wing.  We 
will use this measurement in a bit to 
check our Center of Gravity (CG). 
 
Use the supplied nylon mounting bolts 
to  attach the wing onto the fuselage. 
Make sure that the wing bolts are in 
place and snug before each flight to 
prevent the wing from coming off dur-
ing flight.
