SUMMARY
The Multiplex MiniMag is a smaller version of the popular
Multiplex Magister trainer. Like the rest of Multiplex’s Elapor
foam models, the MiniMag is very durable and offers the convenience of a fully molded foam airframe that can be quickly
assembled using regular CA. Once at the field, its flight performance will make you smile while you polish your skills or simply relax with an inexpensive fun flyer you don’t have to worry
about breaking. Add ailerons and a brushless motor upgrade
for more performance and the float kit for even more fun.
108 FLY RC MAGAZINE
re you a new RC pilot, unsure of your flying skills, who needs a stable,
easy-to-fly model? Perhaps you’re more experienced and looking for a
model with enough control and power options to customize it to suit
your preferences? The MiniMag from Multiplex USA offers all this and more.
The MiniMag is compact and easily stored and transported, and it flies like
a larger airplane—smooth handling and great stability. It is molded by
Multiplex in their proprietary Elapor foam. Elapor is known for its durability
and ease of assembly with traditional CA adhesives and kickers. Foam-friendly
glue is not needed here; in fact, its use is discouraged, as is that of epoxy. I used
medium and thick CA and kicker from Mercury Adhesives. The MiniMag is so
small and light that even after a few good hits, I have not needed to reach for
the glue bottle since its initial assembly. This durability is a welcome change
from more fragile foamies or balsa construction.
The MiniMag is a great sport model for smaller fields, and the brushless
power and float options really make it fun.

AIRBORNE
TIPS FOR SUCCESS
The MiniMag is a well-designed package that goes together quickly and
without trouble. Heed the instructions, and leave the epoxy and foamfriendly CA on the bench. Regular medium-viscosity CA and kicker do
the job with Elapor foam.
The servos are mounted in molded pockets
behind the cabin area. Make sure that the
servo operation and control deflections are all
correct before you seal the servos into place
with the decals.
110 FLY RC MAGAZINE
You only have to mount
the tail surfaces and
attach the control horns.
With its various power,
control and landing-gear
options, the MiniMag
offers the flexibility that
many pilots will welcome.
I recommend that you fly
it in its most basic configuration first. Three-channel control with the
Speed-400 motor gives
smooth control and ample
Beginners and other low-time pilots will
appreciate the simplicity of 3-channel flying
with rudder, elevator and throttle control.
There is plenty of roll coupling with the rudder, so the ailerons really are not needed
for training or general sport flying.
The included S-400 motor is a great
option for training. It is inexpensive, yet it
still gives enough power to practice takeoffs and touch-and-go’s on hard surfaces. I
didn’t have any trouble taking off from the
base paths of the local high school ball
field. Do not expect to get it off a typical
grass field though. If you fly off grass, consider removing the landing gear and handlaunching. With a firm hand-launch, the
MiniMag accelerates and climbs easily.
There isn’t any trouble landing in grass
without the gear, as the relatively short
prop does not extend very far below the
fuselage. Just set up a smooth glide and
flare before touchdown. The MiniMag
glides quite well with power off, so there
isn’t any reason to carry power once you
have made the field. If you do use power to
stretch the glide and you’re belly-landing,
be sure to chop the power just before
touchdown to protect the motor shaft and
the prop from being damaged. If you keep
the wheels on, a gentle flare is all that’s
needed to settle in on the runway. Use the rudder as necessary to
keep it straight on rollout. The optional steerable tailwheel gives you
all the control you need on the ground.
With the stock S-400 motor, the MiniMag will do basic 3-channel
aerobatics. Loops, barrel rolls, hammerheads and limited inverted
flight are well within its capabilities. This setup should more than
satisfy new fliers and experienced pilots who prefer a more sedate
sport flying style. More experienced pilots looking to wring it out a
bit more will appreciate the extra control offered by the ailerons and
the power increase that comes with going brushless. If your sport
flying is on the lighter side, there’s no shame in leaving the MiniMag
as a 3-channel bird. It handles very well without the ailerons, and it
will also be lighter.
The power and aileron upgrades are mandatory if you want to
add the float kit. You will want the ailerons to help keep the wings
level on the water, and the extra power is needed to get off the
water. Hitec/Multiplex USA offers a great combo that drops right in
to replace the Permax Speed-400 brushed motor with a direct-drive
Himax inrunner that gives you the option of going with either 2S or
3S Li-Poly packs and with different props. If you prefer an outrunner
to turn a larger prop, the Himax HC2812-1080 is nearly a drop-in
replacement for both the original S-400 and the brushless Himax
2815. The slower turning outrunner and larger prop are quieter than
either of the other options but with a little less yaw stability and limited top speed. It also requires that you modify the mount slightly,
as there are reinforcing fins in the mount that help to stabilize the
inrunner’s can. The outrunner needs clearance on these fins, and
this is easily achieved with a Dremel tool and a sanding drum or
another abrasive insert. I used one of Robart’s Rough’n’Tough carbide cutters.
Which of the brushless motors is better? It really depends on
your preferences, as both fly the model very well. Hitec/Multiplex
USA offers the Himax inrunner as a complete upgrade package.
They do not endorse an outrunner configuration, as they have not
yet tested one.

Or, try the Magister ...
SPECS
PLANE: Magister
The Magister is a popular midsize
trainer that shares its durable
Elapor construction and convenience with the smaller MiniMag.
If you are looking for a larger,
more stable trainer or sport flyer
with the same “bounceability,”
consider the Magister. Available
as an airframe kit, the Magister
can be powered with a .25 to .40
glow engine or an electric power
system. It is also available as a
full RTF electric package with
installed radio and power systems. All you have to do is mount
the tail surfaces and landing gear

We flew the electric RTF version,
and we felt that its smooth, stable
flight characteristics were well
complemented by its power for its
mission as a introductory trainer.
As is usually the case, pilots who
are looking for a lively sport flyer
could easily upgrade to a brushless/Li-Poly power system for less
weight and more performance.
power for learning how to fly and even general sport flying. Be sure to give it a try in this
configuration before you commit to adding
ailerons. You might be pleasantly surprised.
The arm and actuation of the optional
steerable tailwheel is also used for the water
rudder. If you are thinking about trying the
floats at some point, I recommend that you
install this assembly during the initial assembly. Fitting it after you’ve installed the stab
and fin on the fuselage is a challenge.
With the fixed water rudder, the handling
on water was a bit squirrelly. Full-scale technique dictates that you retract the water rudder before you start your takeoff run—and for
good reason. Aggressive inputs at speed can
cause the water rudder to grab and slew your
model sideways. Despite the manual’s admonitions, I removed the water rudder after my
first few flights off water. No question, this
compromised slow-speed handling, and the
reduction in the aft area makes the model a bit
more twitchy in the air; but at transitional
speeds on the water during takeoffs and landings, the handling is much improved. I think
the best solution would be to alter the water
rudder’s shape so that it’s clear of the water
once up on step. Raising the lower edge an

inch should be enough, and adding that
removed area to the back of the rudder will
help to maintain yaw stability. Removing the
water rudder is easy, so it’s easy to try a couple of different shapes. Another option for the
calmer conditions this model prefers would be
to add a sub-fin that’s equal in area to the
water rudder and then to depend on the air
rudder for steering.You might be pleasantly
surprised.
CONCLUSION
Whether you’re looking for the simplicity of
an economical, durable, 3-channel trainer or
an everyday full-house sport flyer on wheels
or floats, the compact, easy to transport
MiniMag deserves your
close attention. Its resilient
airframe and smooth, predictable performance will
quickly make the MiniMag
your “go-to” model for
your first steps into RC or
for a daily flying session to
relax at lunch or on the
way home from work.
With options for brushed
or brushless power, 3 or 4
channels, hand launch, wheels, or floats, you
can customize your MiniMag to suit your
preferences and upgrade it as your skills
progress. This is one model that will keep
your interest for quite a while. =
