13. Use industrial strength Velcro to attach the battery.
It is a good idea to cut the covering out from under the
Velcro and attach the Velcro directly to the foam with
some medium CA. Also, glue the 1/32” ply connector
plate to the wing and the battery connector to the con-
nector plate using medium CA.
Center Of Gravity
The center of gravity is located at 7 1/2” from the
nose. Make a mark 7 1/2” from the nose of the wing
and attach the battery so that it balances on this mark.
Control Throws
Measure the control throws at the widest part of the
elevon.
Mild
Aileron: 1/4” Up, 1/4” Down
Elevator: 3/8” Up, 3/8” Down
Wild
Aileron: 5/8” Up, 5/8” Down
Elevator: 5/8” Up, 5/8” Down
Reflex
You will need to have a slight amount of UP eleva-
tor dialed in to the elevons. This is called reflex. All
wings need a certain amount of reflex to fly. Start with
about 1/8” up, measuring from the widest part of the
elevon.
