Great Planes Pitts Special 1/3 Scale ARF MonoKote - GPMA1218 - Manual (Page 8)

❏ 1. If you have not done so already, remove the major
parts of the kit from the box (wings, fuse, cowl, tail parts,
etc.) and inspect them for damage. If any parts are
damaged or missing, contact Product Support at the
address or telephone number listed on page 3.
❏ 2. Remove the masking tape and separate the ailerons
from the wing, the rudder from the fin and the elevators
from the stab. If necessary, tighten the covering with a
covering iron on high heat. Use a covering sock on the iron
to prevent scratches on the covering. Apply pressure over
sheeted areas to thoroughly bond the covering to the wood.
❏ 3. In this manual you will notice boxes placed in front of
each assembly step. These boxes are provided so that you
may place check marks in them as you progress through
the assembly process. If multiple boxes are present, this
step needs to be repeated.
Important note: The Pitts Special ARF is capable of being
assembled with the option of using four aileron servos. Or
two aileron servos could be used in the bottom wing only,
along with connecting rods between the top and bottom
ailerons. In this manual we will show only the use of four
aileron servos, but extensive testing was performed with the
two aileron servo equipped version. This testing resulted in
very positive response. Even during our very demanding
stress testing, no problems were found.
❏
1. Drill a 3/32" (2.4mm) hole, 1/2" (13mm) deep in the
center of each hinge slot to allow the CA to “wick” in. Follow-
up with a #11 blade to clean out the slots. Hint: If you have
one, use a high-speed rotary tool to drill the holes.
❏
2. Use a sharp #11 blade to cut a strip of covering from the
aileron hinge slots in all four wing halves and ailerons.

IMPORTANT NOTE: While assembling the Great Planes
Pitts Special ARF, you will encounter a number of areas that
require the installation of various brackets and other items.
Most of the locations for these attachments have predrilled
holes for these applications. The attachment screws do fit
correctly but tightly. We highly recommend that you first drive
the attachment screws into the predrilled holes with a regular
screwdriver, then remove each screw, and thoroughly
saturate the threads you have created in the hardwood with
thin CA. After letting the CA set completely, continue with the
assembly by driving the screws back into the threads you
have created, being careful not to overtighten. Since these
areas are subject to high stress, we strongly recommend
that you DO NOT use an electric or battery powered drill or
screwdriver for this as you can very easily overtighten the
attachment screws and weaken the threads you have
created in the hardwood blocks. Use this technique on all
areas of the model when you attach anything to the model
using screws. Extensive testing of this technique has shown
that this method greatly increases the strength of the model.
