egatech International offers an incredibly diverse line of radio control
models, running the gamut from park flyers, beginner’s startup cars
and boats to their 40-class Nitro Air Strike Trainer and 40-class
Floats. Recently, Megatech has widened their airplane selection with 40-size,
glow power versions of their electric RC and free flight models, the Capitol
Flyer and the SkyLiner.
The Nitro Capitol Flyer and
Nitro SkyLiner are available in
both the ready-to-fly and almostready-to-fly formats. The RTF versions come fully factory assembled,
and are equipped with the rugged
and reliable M-46 two-stroke
engine and a factory-installed

with buddy box. These models are
virtually ready for action within 15
minutes of opening their boxes.

limiting their “work” time to charging a radio system.

an Airtronics flight pack
and a Megatech M-46
engine from my own

The Nitro Capitol Flyer and Nitro SkyLiner both come with their engine mounts installed, and their fuel tanks
and fuel lines installed and ready for hookup. The engine lugs are sandwiched between the aluminum mounting
rails and two steel caps, secured on each side by a pair of Phillips head screws, washers and hex nuts.
Assembling the models begins with joining the wing panels. No adhesive of
any kind is needed. The wing halves slip over a sturdy joiner that sandwiches a
piece of T6 aluminum between two layers of hardwood. Megatech has also
developed a novel way of keeping the
wing panels together. The dihedral
brace and the bottoms of the wing
Pushrods are factory assembled
and require no additional assembly. Servo trays accept most standard servos. Airtronics 102 servos were used in HM’s review models.

panels are drilled to accept a pair of bolts that secure the panels to the joiner.
The bolts each have a a wingnut jammed tight to their heads for easy threading,
so no tools — not even a screwdriver — are necessary to assemble the wings.
Megatech’s M-46 and other engines of similar displacement will fit nicely
into the factory-installed aluminum engine mount. The mounting rails are
drilled to accept a pair of Phillips head screws that pass through two steel
plates and retain the engine between them. No need for a nut driver for the hex
nuts under the mount; the mounting rails have hex-shaped recesses to prevent
the nuts from turning as the screws are tightened.
Once the engine is mounted, the throttle pushrod can be connected to the
throttle arm, and the muffler and gasket
mounted with the two hex screws.

No glue required. Two threaded
rods at the base of the vertical fin
pass through holes in the horizontal stabilizer. These, in turn, pass through the fuselage, where they
are retained by a pair of washers and wing nuts under the fuselage.

This is a good time to mount the tail surfaces, and

Once the rods are in and the controls checked, the
modeler has only to adjust the control deflections to the
recommended measurements, make sure the RC system is
fully charged before heading for the flying site.
Engine break-in is matter of preference. While many
modelers believe in extensive bench running before flying
an engine, I have always believed that the results can be
just as effective, maybe even a little better, when breaking
an engine in on a model in flight.
Once at the flying site, I range-checked the radio gear,
then filled the tank with a 15 percent nitro/18 percent
50/50 oil blend and drew the propeller through a few
turns. I put the heat to the glow plug, hit the spinner with
my Megatech starter and the mighty Megatech M-46

96 FEBRUARY 2003 HOBBY MERCHANDISER
With zero degrees of dihedral, the Nitro Capitol Flyer
becomes a very aggressive model, able to perform inverted
flight as easily as upright, and spins and rolls in every
direction on command. Limited experience pilots should
be told that the flat wing requires the addition of rudder
during turns to keep the model from slipping or sliding
excessively in the yaw axis.
Either way it’s set up, the Capitol Flyer is a great airplane, and one heck of a smart choice for the pilot who
wants a solid trainer but doesn’t want to buy another
model when it’s time to take the next step forward.
I let the airplane have its head while the runway
slipped gradually away beneath its belly, then I applied a
little aileron input to see how the model would react in a
turn. The SkyLiner begins to roll with the application of
aileron, then the high dihedral begins to induce a very soft
turn. A bit of back pressure on the stick while the airplane is coming around will complete the turn smoothly.
The SkyLiner exhibits no threat of tucking or dropping a
tip, and is an absolute delight to fly.
The Nitro SkyLiner and Nitro Capitol Flyer are both
excellent performers, although there are very distinct differences between the behavior of the two airplanes. One is
a primary trainer; the other can be anything you like.
Good looking and rock steady, Megatech’s nitro trainers can make learning to fly RC almost effortless.
Megatech’s ARF nitro trainers assemble quickly and
fly very well. The covering is durable and attractive, and
the quality of the workmanship is equal to or above that
of other factory assembled aircraft models. Dealers should
remember that these airplanes are also available in the
RTF format, with engines and radios factory installed.

Settling in on final, the Nitro SKyLiner maintains its
stability at all speeds, even in the stiff winter wind.
The SkyLiner has a flat bottom wing with a slight
Phillips entry, and is therefore very predictible and easy to
stay ahead of at all times. The Nitro Capitol Flyer has a
semi-symmetrical wing and will deliver far more aerobatic
agility in the hands of an experienced RC pilot.
Unlike the SkyLiner, the Capitol Flyer comes with
two wing joiners. One is just like the SkyLiner’s, producing a high dihedral that keeps the airplane on an even
heading and helps to prevent Dutch roll. The other joiner
has no dihedral, and installing this joiner and the accompanying center shim results in a perfectly flat wing.
