Unpacking
Carefully unpack the model, when opening the plastic bags make sure you do not to cut any
covering on the model. Inspect each item to make sure there was no damage in shipping. If for
any reason, you are not happy with any part or are unsure please contact the Dealer that you
purchased your plane from.
Covering
Because of the multiple climate zones encountered on the trip from the factory to you, some of
the covering may have wrinkles. We highly recommend that you take time to reseal all covering
edges with an iron and to use a heat gun to remove any wrinkles and retighten the covering. It is
best to do this now before the plane is assembled.
*Note: Be careful not let any heat get near parts like the canopy or cowl as this may cause
damage.
Assembly Tips
We also recommend that you go over all the accessible joints with cyano glue. Wick glue into
areas of high stress around the U/C plate and motor box.
Use a quality Thread-lock on all metal to metal joints. Even if your model is electric powered with
lower levels of vibration the thread-lock will ensure that things do not fall off of your airplane!!

Landing gear:
First, screw the flange nut into the axle, then use the self-locking nut to lock the axle on
the landing gear, remember to use a washer between the self-locking nut and the landing
gear, and then press a plastic gasket, The sequence of the shims is to load the wheel into
the axle, and finally insert the pin into the axle hole to lock the wheel. Repeat for the other
side.

Flaps:
The epoxy rudder angle is glued to the wing; the carbon fiber rudder angle is glued to the flap,
with two holes in the middle. The two rudders are then connected using a screw.

Rudder Installation:
The tail wheel must be installed. First, drill the four screw holes with a hand drill and drip CA in
the holes to harden them. Then lock the servo with self-tapping screw. The mounting holes of the
servo mounting plate also need to be fast-dripped and then tightened with self-tapping screws.

find the cockpit suitable placement, use paper tape to be fixed, and then use the drill on the left
and right sides of the two holes to play, before and after the middle position of the play a hole.
Pour a little bit of each hole into the quick-drying glue, and then use the self-tapping screw
