SECTION 1: OUR RECOMMENDATIONS

This section describes our recommendations to help you in deciding which types of accessories to purchase for your
new Modeltech Simply Magic 40 ARF. These suggestions are not set in stone, but they should provide you with a good
starting point.
What Engine Should I Use?
The Simply Magic will accept a wide variety of engines, so which engine you choose really depends on how you want to fly
the airplane. For general sport flying, a .40 to .52 2-stroke engine with a 10 x 6 propeller (for a .40) or an 11 x 6 propeller
(for a .46 or .52) would be perfect. If you want to use a 4-stroke engine, a .61 4-stroke with a 13 x 5 propeller would be a
good choice, too.
For 3D style aerobatics, you want to focus more on using lightweight, but powerful, engines with large diameter, low pitch
propellers. There are many engines that fit this criteria, so it really depends on how much money you want to spend. For
good 3D performance and a low price, a good sport .46 size engine with an APC 12.25 x 3.75 propeller would be perfect.
We recommend using our new Magnum XLS .52 two stroke engine. It's lighter than its .46 size brother and can spin the
same APC 12.25 x 3.75 propeller a couple hundred RPM faster.
What Radio System & Servos Should I Use?
For typical sport-flying and general aerobatics, a standard 4 channel radio system will be more than adequate. Since the
ailerons use separate aileron servos, you will need to use a servo Y-harness to join them. The Simply Magic is not a big,
heavy airplane, so it's not necessary to use high-torque servos. Five standard size servos will work fine.
For 3D aerobatics, a four or more channel computer radio with mixing capabilities will be required. Since there are two
separate aileron servos used, they can be plugged separately into the receiver, allowing you the capability of flaperon or
spoileron mixing and differential. For 3D aerobatics, we still recommend standard size servos, but we strongly suggest
using ball bearing servos on the control surfaces.
What Else Do I Need?
The Simply Magic includes all the hardware you'll need to finish the airplane. You will need some basic building materials,
such as adhesives, protective foam rubber for your radio gear, and fuel tubing. We've provided a list below of the items we
used on the airplane shown in this instruction manual.
