Section 1: Our Recommendations - Model Tech SE5a SCOUT Instructions For Final Assembly

SECTION 1: OUR RECOMMENDATIONS

This section describes our recommendations to help you in deciding which types of accessories to purchase for your new
Modeltech SE5a Scout ARF. Please read through this entire section very carefully. We have provided you with tips
and recommendations that, if followed, will result in a great flying airplane. Failure to follow our recommendations
may result in a poor flying airplane.
The SE5a Scout ARF will fly well with a variety of different engines. The airplane is designed to be flown with .40 - .52 size
two-stroke engines or .52 - .61 size four-stroke engines. Whether you plan on using a two-stroke or a four-stroke engine,
the firewall has been set up for the engine to be mounted upright. This is ideal because the engine can be fully enclosed
within the cowling and engines that are mounted upright are very easy to tune and maintain.
If you choose to use a two-stroke engine, you will need to purchase a muffler extension for your engine's muffler. This will
allow the muffler to be pushed out far enough to clear the side of the fuselage. If you're using a four-stroke engine, the
engine's exhaust pipe can be rotated to exit the upper, right side of the cowling, so no muffler extension is necessary.
A standard four-channel radio control system with 3 standard servos for the elevator, rudder and throttle, and 2 mini servos
for the ailerons will be more than adequate. Since the ailerons use separate aileron servos, you will need to use a servo
Y-Harness to join them. A standard flat or square 4-cell receiver flight battery will work well, too.
IMPORTANT Because of the thin airfoil, you must use mini servos for the ailerons. Standard-size servos will not fit
within the confines of the wing.
The SE5a Scout ARF includes most of the hardware you'll need to finish the airplane. You will need to purchase separately
a remote fueling valve, two servo extension leads and one Y-Harness for the aileron servos, and some basic building
materials, such as adhesives, protective foam rubber for your radio equipment, and fuel tubing. We've provided a list
below of the items we used on the airplane shown in this instruction manual.
