Step 8: Finishing the Kit
Attaching the Battery
You will need:
•
6" Velcro strip for mounting the battery and receiver (Bagged Parts)
!
Getting the battery to stay where it belongs
Cut the rough side of the Velcro strip down to 3" in length, and then attach it to the side of
1.
the fuselage where you glued the 1/64" ply sheet..
Attach the soft side of the Velcro strip to the top of your battery pack.

Setting the Throws
You need to adjust your radio trim so that the elevator, rudder, and ailerons are all level.
The throws are as follows:
Low Rates
+-30 degrees (.75" total travel)
Ailerons
+-30 degrees (3" total travel)
Elevator
+-30 degrees (1" total travel)
Rudder
Setting the Center of Gravity
The Center of Gravity (CG) will affect how the airplane recovers from a nose up or nose
down condition (pitch stability). With the CG too far forward, the plane will be quite stable,
but require a lot of up elevator to fly level. This will result in an increased low end speed. On
the other hand, too far back and the plane will be hard to control, requiring constant input
to keep the plane flying straight and level. As this is a 3D plane and stability takes a back
seat to maneuverability, I like to set my CG 4" – 4.25" behind the leading edge of the wing.
Setting the Lateral Balance
The lateral balance is along the length of the airplane. Because we mount the battery on
one side of the fuselage, the balance will be off. You can easily check the balance by resting
the propeller shaft on a finger and gently lifting the rudder with your other hand such that
the airplane is completely off the ground. If the plane rocks to one side, the balance is off.
I found that, on my Panic, a quarter and a nickel on the wingtip opposite the battery
balances the plane nicely. I cut a slit in the end of the wing and pressed the coins into the
slit.
