HATCH & CANOPY
1.
Gather the following items
(1) Canopy Hatch
(4) 4-40 x 1/2” Socket Head Bolt
(4) #4 Washer
(1) Canopy
Place wax paper.between the hatch and the
fuselage.
Using the 4-40 x 1/2” bolts and washers,
mount the hatch to the top of the fuselage.
Put in place the canopy over the fuselage
hatch.
Glue in place using canopy glue..
Balancing
Your model should balance at 5-3/4” to
6-3/4” back from the leading edge of the
wing next to the fuselage. For extreme
3D flying you may want to move the CG
back even farther after you are comfort-
able with the
Extra 330
. Just remember
that the further back you go the more
sensitive it will become. With extreme
throws the model can get beyond the
ability of novice pilots very quickly.
Start with the controls set at low rate with
the ailerons plus or minus 1/2”, the ele-
vator plus or minus 1” and the rudder
plus or minus 1-1/2”. High rate should be
all you can get.
Good Luck and I hope you enjoy flying
the
Extra 330 ARF
.
