Flight Trim:
The recommended center of gravity (CG) point is
6-3/4” from the LE at the wing root with the battery in-
stalled. Adjust by positioning the battery by moving the
G10 plate and velcro strap on the fuselage for the new
battery position.
A good test for an aerobatic CG position is to fly the
plane upright and trim the elevator for level flight. Then
fly inverted and see if any down elevator control is needed
to maintain level flight.
I
f the plane also flys level in-
verted with
very little down elevator,
the CG is good
for 3D. The farther back your CG moves, the more
“twitchy” your elevator will get. For 3D It helps to have
40 to 50 degrees deflection on all surfaces and a rear-
ward CG. 30 to 50% expo may also be helpful on all
surfaces (Especially elevator). Adjust to your taste.
You may wish to check and adjust
lateral balance
.
It should be very close to neutral if built as shown.

Notes on Crashing and Repairs:
You should be able to fix foam damage with Quick
Grip for fast field repairs. Apply Quick Grip to one sur-
face, join parts temporarily, pull apart to let dry for about
30 seconds (you should see “spider webs”) and then put
them back together. In a few minutes the joint will be
flight ready. Large damaged areas will benefit from Go-
rilla glue as it foams to fill voids.
Have Fun!
Remember, weight is the enemy, so keep repairs
light! If there's one thing we've learned, it's amazing how
much cosmetic damage can be "ignored" when a friend
shows up to fly.
We want you to have fun exploring the limits, but
please do so safely.
We welcome any feedback you may have on this or
