1. Center of Gravity

❑ Repeat the previous procedures to install the second outer wing panel to the center wing panel, using the remaining two flange-

head machine screws provided.

pRo Tip When you disassemble the wing panels, we suggest leaving the wing joiner tubes installed in the center wing panel.

CeNTeR oF gRAviTy:

The C/G is located 3-1/2" (89mm) back from the leading edge of the wing, measured at the sides of the center fuselage pod.

iMpoRTANT If you have installed the optional retractable landing gear, make sure to balance the airplane with the landing

gear retracted.

CoNTRol ThRowS:

Ailerons: 7/8" (22mm) Up and 5/16" (8mm) Down

Elevator: 3/4" (19mm) Up and 5/8" (16mm) Down

Rudders: 5/8" (16mm) Right and 5/8" (16mm) Left

Flaps:

Down As Much as Possible

FlyiNg TipS:

Because the landing gear retracts rearward, there will be a change in the airplane's trim. While the change in trim is small, it is

●

noticeable and you should be aware of it.

When you deploy the flaps, the airplane will have a tendency to balloon upward and will require some down elevator trim to

●

counteract this. We suggest the first few times that you deploy the flaps at altitude until you are familiar with the flight characteristics of

the airplane with flaps down. You may want to program elevator/flap mixing in your transmitter so that the required amount of down

elevator is automatically commanded when you deploy the flaps.

BALANCING, CONTROL THROWS AND FLYING TIPS

❑ Carefully thread one flange-head machine screw through the predrilled

hole and into the aluminum wing joiner tube. Tighten the screw gently.

Be careful not to overtighten it or you might strip the aluminum.

iMpoRTANT The machine screw will cut threads into the softer

aluminum without a problem. If you want to, you could use a 3mm tap

to cut the threads, but it's not really necessary.

❑ Firmly push one outer wing panel tightly up against the center wing

panel.

❑ Repeat the previous procedures to install one flange-head machine

screw into the center wing panel.

❑ Glue the radiator scoops onto the wing assembly. The shorter radiator

scoops are glued to the center wing panel and the longer radiator scoops

is glued to the outer wing panels.

iMpoRTANT The control throws are measured at the widest point of

the control surfaces.
