accurately with the spinner backplate. There should be an even gap about 1.5 mm
wide between the spinner backplate and the cowl.
You will probably need to cut various openings in the cowl to clear the cylinder head
and glowplug, the silencer, the needle valve etc.; the positions vary according to the
motor you have installed. Drill and file out the holes as required.
The final step is to trim the undercarriage root fairings to fit. Glue them in place using
UHU ALLESKLEBER kraft adhesive.
Assembling the EXTRA 300 SHP
To make it easier to connect the aileron servos to the receiver, we recommend that
you connect a 180 mm extension lead to each of the appropriate receiver sockets (2
and 5).
Fit the wing joiner tube through the fuselage, and slide both wing panels onto the
tube. Fit the four plastic screws to hold the wings against the fuselage sides, but
tighten them only to the point where the wings are firmly seated. The screws are
supplied overlength; they can be shortened by about 20 mm if you wish.
Connect the aileron servos to the extension leads attached to the receiver.
Balancing the EXTRA 300 SHP
Support the assembled model (fueltank empty) under both wing roots at a point
about 150 mm aft of the wing root leading edge. If the CG position is correct, the
model will hang level, with the nose inclined slightly down. If necessary, glue lead
ballast to the nose or tail to obtain the correct balance, or re-position the receiver
battery. All the control surfaces must be exactly at centre when the transmitter sticks
and trims are in the neutral position; check this before the first flight.

We recommend that you set the following exponential values at the transmitter:
Ailerons

Important:
When fitting and adjusting the various linkages you should ensure that they move
freely, without binding, are able to move to their full extent - including trim travel - and
are not obstructed mechanically at any point.
When you move the rudder stick to the right, the rudder should also deflect to the
right (left stick: left rudder). Pull the elevator stick back towards you, and both
elevators must deflect up (stick forward: elevators down).
If you move the aileron stick to the right, the right aileron should rise, the left aileron
