| Building |
This is PURE pleasure. I belong to the group of people who don't like to
build planes, but this is a game, a LEGO game. All the parts are so
smartly designed, they fit one with each other in a perfect manner.
At this level, this plane is also a perfect trainer, for someone to
learn the basics of building a plane, like reading carefully the manual,
following steps patiently, etc... The Elapor can take any glue like Epoxy
or Cyano, as well as any painting, if you don't like the proposed decalc.
It takes not a lot of time to build it, but it is so nice, that you
really want to take the time, to make it look perfect, as it is
possible. the manual is written in several languages with 2 a VERY precise
and well made list of pictures to illustrate. You could just build the
plane by looking at all the pictures, since they are so clear.
You will notice that the Magister is high on his feet... on his wheels.
This is also very convenient, as to use a large prop. Also, since it is a
big plane, it is easy to fit any battery inside the plane. Replacing the
batteries between each flight is also easy, and well designed. No need,
like on some other planes, to remove the wing or spend 5 minutes using
your little fingers, in order to switch batteries.
At the end, the plane weights 1740gr (61.37 Oz), just without the
battery. Adding the 8x3000 NiMh makes it 2235gr (78.84 Oz)

Building TIPS
- Nose wheel, check the direction: make sure the shock load
bends and do not unfolds !!
- Remove the center part, with pictures,
to work more easily with the manual instructions
- Check, when installing the firewall,
that you follow exactly the directions given from the manual. You
should end up with the firewall, parallel to the fuselage. If it goes
down, one of the pieces is inverted
- Extend the nose wheel as far down as
possible
- Add carbon fiber tube, at the tail, in
order to protect the tail, and tail horn, during take-off and
landings, as that the carbon fiber will touch the ground, before the
tail could
- Using 2 aileron servos is a nice
upgrade. Easier to set up later, and enables flaps if you like to use
them
- Adding carbon fiber tape, below the
wings would reinforce it well
- Reinforce the part which tie the cockpit
to the fuselage. Epoxying or adding Cyano inside the place where the
screws enter, might be a possible solution
- When entering the screws to hold the
tail elevator part, make sure to not force it too much or the screws
would simply "eat" the foam and drill into it. If this
happens, then just glue the tail and forget about the screws
- Replace the recommended servos with
lighter, smaller ones. HS-81 or GWS PARK HPX will do fine
Special note from Spash99: "The
only thing I disagree is your mentioning epoxy as a suitable glue, in my
experience with the ES epoxy peels of the Elapor.
I had good results with CA and PU glue, and heard from others that hotglue
works as well"
Note that some of the tips above were given by Ezoners, from the
main Magister Thread. Splash99, Bill Glover, TreeTop and others...
One last thing, not related, the piece which attach the aileron horn to the
wire, is gone so the right aileron stopped working, I suppose due to the
vibrations, during all these previous flights. For some reasons, I only noticed
it after landing... So just add some Cyano to lock the screw, once
installed.

| Take-off |
Piece of cake. This plane behaves
perfectly well here. Clear path, smooth take-off
- Pull slightly the elevator, and maintain until in the air
- Full speed (beware of torque effect depending on the motor)
- Correct path with rudder, as necessary
- After take-off, maintain full speed, until you get to safe altitude,
level flight, then you can initiate a turn and reduce power as needed.
|
| Flight behavior |
A PERFECT trainer, with no surprises. I
tried stalls, and the plane just gently drop his nose and you are back on
track. The plane is not build for stunts, and I did not try any for now
though, but anything a normal Cesna would do, this Magister did it well.
As any trainer of this size and weight, the plane does not like to steep
bank on low speed, but like any normal plane. It glides really well, and
again, just on a clean path, like if it was on rails.
Flight tests
- Loops are piece of cake, from level flight. Just make sure you have
enough speed and don't wait at all, while on the edge as the plane is
heavy and will drop
- Flaps help A LOT, for landing on short runways, I tried with and
without and without is much more difficult as the plane either glides
quite well. Since the stall speed seems pretty high, the plane, when
touching the ground is still fast and it's weight takes it for some
time on the runway. Make sure to have at least a 25 meter (82 feet)
runway to be safe
- When the flaps get extended, there is no need to modify the elevator
at all
- The plane needs rudder management, in order to achieve
clean and coordinated turns. This is certainly due to its size and weight,
but it is required. Not doing it makes the plane slide, like any real
plane would.
- The rudder is not just here to be nice, on this plane, it works
effectively. forward Slip on landings are therefore easy to do, and it might be a good
way to slow the plane down, if too fast on final approach
- Beware of the elevator. It is very sensitive. Never forget than if
you pull to fast on the elevator, you might stall, regardless of the
plane's speed ! I actually tried to force a stall at high speed and
sudden sharp elevator up but did not succeed. Possible that I was too
slow anyway.
|
| Landing |
Smooth, clean, a real pleasure. The
landing gear is also well done and absorbs shocks very well. Flaps do help
to reduce the landing distance |
| Crash Results |
Elapor, so 5 minutes Epoxy or Cyano and you are
back in the air :) |

What
makes this ARF kit far above the competition
- ALL the pieces are inside the kit. You are not asked to find special
parts, bend Z wires, look for pieces to attach the wires to the horn
and on the top of this, all the parts
fitting perfectly, no extra work needed. There is even a screw driver
for locking the cockpit screws, on the field. Never saw that in any
other ARF kit before.
- Holes for cooling pre-made
- 2 gains for re-enforcement of the piano
wires (smart and light)
- Space for the wires to move freely, when
the servo moves
- Sold with the kit Firewall, which is
very smartly done and fits perfectly the plane. It is a little heavy
but it can therefore handle heavier motors
- Possibility to have this plane made for
glow or electric. The kit contains the different parts to build it
either way + special explanations in the user manual for each setup
- Towing system is smart and efficient.
How many ARF electric plane come, out of the box, with a simple to
build towing system ???
- The price you pay for this kit is MUCH
cheaper than many foam, EPP other ARF kits, when you compare the
quality put in the Magister.
- The battery location is right in the CG,
meaning you can put whatever battery you like, without worrying about
CG impacts
AND MUST
OF ALL, it flies GREAT !!!!
I was thinking who could
beat Multiplex, in the Foam area, in terms of ARF, easy to build quality
kits and quality of flying.....
Multiplex beats itself in
this arena, and this time, from a large margin !!!! This ARF kit is the
nicest I came across so far, and the flight quality of this trainer are very
complete
Selected Gliders to be towed:
-
Robbe
LO 100 (Wingspan 980mm (38.5'') - Total
surface area approx. 13.9 dm2 - Total surface loading min. 11.2 g/dm2
- All up weight min. 145 gr.)
-
Ikarus
Champion (Wing span 1350mm (53'') - Weight
240g (8.5oz) -Radio requited 2 channel)
Towing test report
The Magister
"out of the box" towing mechanism controlled the glider without any
problem
Few remarks:
- Glider's structure was too weak to handle the stress
- Magister needs some minimum speed which seems already quite a lot for this
glider
- The Magister was Excellent, during all the towing test. Immediately released
the glider, after accident, and it had no problem, during all the test.
Conclusions:
- Needs to find a heavier/stronger/faster glider to pull
- Needs to use a longer wire, between the 2 planes, to absorb the tensions
- It is so fun to do, we will try this again, VERY soon, until it will become a
routine
2nd try of towing, this time with the Windrider Easy Glider:
It worked !!!!!
Bomb Test release using the Tow mechanism

It
worked great, just watch the video
