The  fuselage  ply  sides  provide  space  to  mount  your  switches  just  below  the  canopy.    Mount  your 
switches  according  to  the  manufacturer’s  instructions  and  route  your  wires  safely  and  securely  as 
above.   

3.

 

Your  receiver battery(s)  can  be  mounted  in a  variety  of  locations depending  on  your  balance  needs.  
Regardless of where you mount your batteries it is vital that they are very secure with no possibility of 
coming loose.  Use double sided Velcro to hold the batteries from sliding around and then use zip ties 
or Velcro straps to secure them tightly in place.  

4.

 

Servo  and  battery  leads  are  the  life  blood  of  your  aircraft.    Make  sure  all  wires  are  top  quality  and 
connectors are tight and display no loose pins or frayed wires.  Servo clips are provided in the kit for 
your convenience.  These servo clips can even be glued to the wood structure using CA if desired.   

5.

 

Check  all  radio  programming  and  control  surface  operations  thoroughly  before  your  initial  flight.  
Check your radio range according to the radio manufacturer’s instructions both with the engine off and 
running. 

 

Balancing and Pre-Flight Checks 

Most state of the art aerobatic aircraft allow for a wide margin for balancing depending on what level of 

precision or freestyle flying the pilot prefers.  To perform properly without being too pitch sensitive, you 
must not go too aft on the CG.  GoldWing RC recommends an initial CG setting of 

 

127-137mm(5-5.4 

inches)  behind the leading edge of the wing at the root.   More experienced pilots may want to set the 
CG further aft for more 3D capability.  Varying weights of engines and radio gear will dictate how you 
should install each.  The batteries can easily be located pretty much anywhere in the fuselage.  For those 
using a heavy engine, servo cutouts are provided in the rear of the fuselage for the rudder servos.  These 
options should allow you to balance the model without adding any weight. 

Note:  The best way to check your balance is to trim for level flight at about 1/2 to 3/4 throttle and then roll 
inverted.  The aircraft should maintain level flight with very little to no down elevator input.  If the aircraft 
climbs when inverted then you’ve probably got your CG too far aft.  If the nose drops more than slightly, then 
you are most likely nose heavy.   

Recommended control surface deflections: 

  

Low Rate 

High Rate 

Elevator 

15 degrees 

45-50 degrees 

Rudder 

25 degrees 

40 - 45 degrees 

Ailerons 

25 degrees 

35-40 degrees 

 

 
Final Assembly and Pre-Flight Inspections 

1.  Before arriving at your flying field, be sure all your batteries are properly charged and all radio systems are 
in working order.  

2.  Install the wings onto the fuselage being careful to align the wing tube with the wings and not force it.  The 
wing tube may be initially tight but will loosen after some with use.  Guide your servo wires into the fuselage 
openings  and  connect  to  the  correct  aileron  channels.    Servo  clips  are  recommended.    Once  you  have  the 
wings fully seated in the fuselage tighten the wing bolts inside the fuselage.
