their thumb/finger prefer not to have so much Expo. It’s all in how it
feels to you, the pilot.
Power. The general rule of thumb is that you need a 2:1 power-
to-weight ratio. This gives you the ability to hover at a throttle setting
of less than full power and leaves you with reserve to get out of
those bad situations. Generally when I am hovering it is at 1/4 to 1/3
throttle. When hovering down low, there isn’t much room for error, so
having the ability to punch out of a bad situation is a must. This extra
power also allows for variances in the type of hovering you do.
Focus. There are 2 things I focus on when hovering, one is visu-
al visual and the other is mental. The visual portion is just that,
where are my eyes looking? I personally look at the canopy area of
the plane when hovering. This way I can see the whole airplane. I
also know that if the rear of the canopy is below my eye level, I am
about to touch the rudder to the ground. But generally I try to see the
whole plane, this gives me the best idea of the actual attitude of the
plane and the control inputs I need to give it. The mental aspect of
hovering is to think ahead of what the airplane is going to do. While
torque rolling, I try to think at least 1/2 rotation ahead of the plane.
So if I am looking at the bottom of the plane, I visualize, in advance,
what is going to happen when the plane rotates to the point that I can
see the top side—and I begin to make any needed corrections while
still looking at the bottom. Good luck to all who choose to explore
this exciting maneuver!

THRUST TO WEIGHT RATIO
The engine must be able to lift the plane vertically, which is a combination of propeller selection and fuel. You need a power to weight
ratio of at least 1.5 to 1. We do not want to hover at full throttle, we
want to ideally hover at half throttle. We need the reserve power
because we are vectoring propwash off the ailerons to generate the
high degree of roll, and this robs lift and requires the increase in
throttle. A high speed torque roll requires the most power, in the
order of 2:1 just to maintain altitude! Suffice to say that this is a very
advanced hovering maneuver! You need a very reliable engine.
Hovering is great until the noise stops!
Do not use an engine that has a history of running hot or lean. On
the average .40 powered ship, look to configure your plane with a
“heli-like” setup. By this I mean, choose a prop with the biggest
diameter and lowest pitch which will function with the landing gear
and flight envelope of your plane. I have found that the 11x4 prop is
outstanding for hovering with most .40 powered planes. The engines
swing it easily, (you do not want to over heat), and the four inch pitch
generates gobs of thrust at lower flight speeds.
Fuel selection is important. Since we are trying to hover at half of
our available throttle, consider using a higher nitro fuel. The more
nitro, the cooler the engine runs. This is because the nitro brings
more oxygen into the engine and this is where the power boost and
substantial cooling takes place. High Nitro causes harm when you
are at high throttle settings and at rpm’s that overcome the cooling
effects of the nitromethane.
FLYING
You might think that heli experience is helpful, but there are conflicts
with that logic. When you stand your plane on its tail, the yaw axis is
controlled by your ailerons, not the rudder. The rudder, (left stick) controls the roll axis! Heli pilots need to teach their fingers some new
tricks or they will find themselves in trouble!
The throttle, of course, is no longer fast and slow, it is now for rising and decending. There is no “chopping the throttle” when you get
in trouble here! Try that, and you will find that tail first impacts break
things on your plane that you have never seen broken before.
Start with transitioning to hover by practicing holding higher and
higher angles of attack and learning how much throttle to add to
compensate for the lost lift, no longer generated by the wings. As
you pass through the 45 degree angle point, you will find that your
speed drops almost to zero very quickly. You’ll need the most right
rudder at around 45 degrees. As you approach vertical, you’ll find
that most planes still want some right rudder, even when hanging
vertically. I believe this has more to do with countering torque than
any other factor, whereas the rudder compensation at the 45 degree
angle is almost all due to “P” factor. (more on “P” factor in a future
column).
If your plane needs too much throttle to make the transition and
you constantly end up gaining altitude in order to get the plane into
the vertical position, this suggests that you are nose heavy, or lacking in elevator authority needed to swing the tail under the plane.
Running the CG aft of the recommended area is tricky business, but
it can make all the difference in a stable transition. Practice is the
key, but keep a careful eye on the fuel tank and the air/fuel mixture
feeding the engine. You can’t afford for the engine to go lean now!
Flying into and out of a stable hover requires power. If your plane
does not have a low wing loading, you may find that it belly flops
when you go to exit the hover. This is due to the rapid transition back
to “wing-borne” flight—this transition may leave you at such a low
airspeed that the wings won’t to hold the plane up. Expect that the
plane will need a boost of power to get it back to “horizontal” flying
speed! Give it this boost just as it starts to pitch over.
Like your first landings, a quality performance takes practice. Start
a bit on the high side to see how your plane behaves and stick with
it. Soon you will be hanging in space. One thing that hovering teaches you is to be a master of your left hand!
Good Luck-Dave Baron
Editor’s note: we asked noted TOC pilot Jason Shulman whether
hovering smaller models was different from hovering large TOC-size
aircraft, and also for his views on the basics of hovering, from setup
to pilot focus.
Jason Shulman: I recently had a great opportunity to judge this first
hand at the Joe-Nall giant scale fly-in. I was hovering my Exhila (one
pound all up weight) on both calm days and windy days. I was also
hovering a few 30% and larger planes during these same conditions.
The first thing I noticed is that in calm conditions, there was really no
difference. Everything was smooth and predictable. But the windy
conditions posed a few differences. The small plane was very sensitive to the wind in hover. Not so much in terms of drift, because
even the large planes drifted. But the slight variances in the wind
would throw the Exhila around, while not really bothering the larger
planes.
I also noticed that the smaller plane would hover, at times, at a 45degree angle (leaning into the wind), whereas the larger planes
would hover at about a 15-20 degree angle in the same winds. This
made the smaller plane much harder to hover. Once you start pushing to a 45-degree angle, you are entering a kind of forward flight
with the associated flight characteristics. So not only are you trying
to balance the plane on its tail, but you are also trying to keep it from
flying forward.
Although both large and small hovering planes will drift in the wind,
one of the most apparent differences is the speed of the drift. When
I hovered the large planes, drift was relatively slow, and smooth
looking. The Exhila was a different story: it scooted across the field
like it was flying level at 1/3 power.
SETUP
When setting up a plane to hover, regardless of size, you follow the
same principles.
Center of Gravity (CG). The CG should be slightly aft so that
the plane is slightly tail heavy as compared to the normal, or recommended, flying CG position. The larger the plane, the larger the CG
range is. On my Exhila, moving the CG back 1 inch can cause it to
be very unstable and almost impossible to fly. On my TOC planes, I
can move the CG back 3-4 inches and they will still be controllable.
Generally, I move the CG back 1/2 in. at a time on the larger planes,
and 1/8 in. on the smaller planes. There is also a point where you
can have the CG back too far and hovering becomes harder to perform.
Control Throws. I have found it best to fly with dual-rates. I set
a low rate, which is good for general or pattern flying and then max
out all of the surfaces for a high rate of roughly 45-degrees of deflection for hovering. I fly thumbs, so I like a little bite of Exponential on
my low rates and a much higher setting on my high rates. My set-up
on Expo is for a “soft-center” feel on both rates. Pilots that fly with
HOVERING TIPS FROM
THE MASTER
by Jason Shulman
The closer you are to the
ground, the faster you
detect, and can react to,
which way you are drifting.
Note that the tail feathers
and the servo gears that
push them are a bit fragile
and not used to contacting
the ground before more
rugged parts of the plane
do!

Thank you for purchasing a VMAR product. VMAR
Manufacturing is committed to delivering superior value
to the RC modeler. Your new EASY 3D is the
market leader in features, ease of use and flexibility.
Please review these instructions before beginning the
simple assembly procedure.
We’ve used metric measurements throughout these
instructions. We know that some of you like metric while
others think that furlongs per fortnight makes a nifty velocity
indicator. If you are in the furlong camp, bear with us….
It’s not a big deal…3 millimeters is stated as 3mm and
3mm is about 1/8 of an inch. Fire up your calculator and
you will find that 25.4 mm makes an inch. In places where
you have to actually set up something according to a
recommended measurement, we’ve listed an
approximate imperial measurement in inches in brackets.
Whenever we’ve used the directional terms left or right ,
they are with respect to the model when viewed as you
would when sitting in the cockpit…that is when viewed
from the back looking forward.
INTRODUCTION
You’ve taken the lid off the box and grabbed the instruction
booklet…you are about 6-8 hours away being ready to go
flying! Now is the time to look over what’s in the box.
Please see the included Packing List and review the
contents and make sure nothing has been damaged in
shipping. Damage or missing components must be
reported to your vendor BEFORE any assembly begins.
Please DO NOT START if something is damaged or
missing. As you can imagine, once you join the wing halves
attach the stabilizers or install your radio or engine your
options for returns are very limited. Your vendor will not be
able to provide you with exchanges or replacements of

HOVERING
What is the attraction to hanging your plane on its nose and holding it otionless and in full control? Simple answer, it’s cool! I am going
to explore the phenomenon, the kinds of planes that hover best and
what you need to know to teach yourself this great flying skill.
PLANES, ENGINES AND PROPS
The most important aspect of your selecting a plane to hover is its
weight. Your plane must be light. Secondly, you need to have substantial control surfaces on the rudder, elevator and ailerons that are
in the prop blast of the engine. Planes that have ailerons
only on the outboard section of the wing are unsuitable,
because with no airflow over the ailerons, there is no control in hover no matter how far you deflect them!
I have found that planes with longer fuselages, while
more stable in pitch, are not necessarily good for hovering. This is because the rudder and elevator are too far
from the slipstream of the prop. You need a strong slipstream over the tail feathers for control.
There are several ways to improve an airplane’s ability to
hover. One is to move the CG aft incrementally—a little at
time so that you can test the result. An aft CG helps a lot in
the transition from normal flight to hover and back, but use
care, as you do not want to go so far that you give up your
stability in normal flight! Another concern is flaperons that
are coupled to the elevator. While this gives the tightest
loops on most fun-fly planes, it does not help in hovering.
In hover, flap deflection on most models sends the plane in
the opposite direction (in pitch) than you desire. I advise
that you turn off this function, or turn it down so less than
10 percent of flap throw is mixed into elevator throw.

My Minus is a great hovering plane that transitions easily to
hover without gaining altitude. It is light, with an aft center of
gravity that is at 35% of the wing chord (from wing leading
edge to aileron trailing edge). The Minus is a Skipp Turner
design. You can reach Skipp at airworthy@aol.com.

Step 24.1 Consult your radio manual for instructions about
hooking up your receiver.
Step 24.2 Plan where you are going to put the receiver
with consideration for routing the antenna safely.
Step 24.3 Wrap the receiver securely in foam suitable for
RC equipment and wrap the foam insulated receiver in a
plastic bag or cling wrap.
Step 24.4 Generally in the absence of specific instructions
from the radio manufacturer, it is recommended that the
receiver should be placed where it is least likely to have
impact during a crash. Keep the battery pack and other
heavy loose items ahead of the receiver.

Step 24
Step 25.1 Consult your radio manual for instructions about
testing and operating your radio system.
Step 25.2 Pay particular attention to charging your radio
system batteries and range testing the system before and
after each flight.
Step 25.3 Check that all controls are working correctly
before and after each flight.
CONFIRM RADIO OPERATION
Step 25
The CG for your Easy 3D is located at 130 - 140 mm
(5 1/8” to 5 1/2”) back from the leading edge of the wing
when the wing has been attached to the fuselage.
For the initial flight, the CG should be located at
130mm (5 1/8”) back from the leading edge of the wing
when the wing has been attached to the fuselage.
The CG is measured with the engine, radio gear and all
other components installed but WITH NO FUEL IN THE
TANK.
Set up the CGI as it will be when you fly it BUT WITH NO
FUEL IN THE TANK.
It is very important to have the CGI correct. Flying your
model with the CG too far will likely lead to loss control and
a crash.
If you discover that after you have assembled your model
and installed your radio and engine that the CG is incorrect
you must bring the CGI to the correct location by doing the
following BEFORE FLYING :
- Move the battery pack fore or aft.
- Move other components fore or aft.
- Change engine to a lighter or heavier model.
- Add weight to the nose or tail. If adding it to the nose,
try to make it useful by going to a heavier duty engine
or adding a spinner with a heavy metal backing plate.
As a last resort, add stick on “dead” weight where
appropriate.
BALANCING THE AIRCRAFT.
Step 26
27.1 Once you have confirmed that the CG is correct, you
should do a thorough review of the entire model before your
first flight. Check everything twice! Every hook up, every
coupling, everything! Do it twice!!
27.2 Before your first flight, have an experienced flyer
review your work. Do not fly your model until it has been
checked out by a third party who knows how to fly and how
to set up a model aircraft
27.3 Once you have completed your first flight, get in the
habit of checking your model over before and after each
flight! Don’t fly if you find something that is not right!
CONFIRM MECHANICAL INTEGRITY
Step 27

CONNECTING THE THROTTLE CONTROL
Step 19
Connect the clevis to the engine throttle arm at roughly half throttle. Look
into the throat of the engine carburetor as you rotate the throttle arm and
select a position where the throttle opening is about half what it is when
fully open.
19A. Typical throttle control connection
Adjust the deflection of the control surfaces to match the
specifications on page 14.
You can reduce the amount of throw by doing either or both
of the following:
From the servo end, move the clevis or EZ connector to a
hole in the servo arm that is closer to the servo output shaft.
From the control horn end, move the horn out further on the
threaded bolts. Always confirm that the horn is still
thoroughly engaged with the threaded bolt after you have
adjusted it.
ADJUST CONTROL SURFACE THROW LIMITS.
Step 20
Before starting the final set-up of the model, switch on the
radio and ensure that all trims are in their neutral positions.
Check that the ailerons, elevator and rudder are centered.
If any adjustments are needed, do these by uncoupling the
relevant control and turning it clockwise to shorten the
linkage or counter-clockwise to lengthen it. Only when each
control surface has been centered mechanically in this way
should you begin adjusting the surface movement
(or throw)
FINAL R/C SET-UP
Step 21
Now confirm that the control surfaces are moving in the
correct direction. Check the up-down of the elevator, the
left-right of the rudder and the roll left-roll right of the
ailerons. Use the reverse switches on your transmitter to
reverse the direction of a servo if necessary. The most popular transmitter mode (with the throttle on the left, with
ailerons and elevator on the right) is shown here.

Step 3.1
Consult your radio instruction manual and center each
aileron servo by plugging it into the aileron channel of
the receiver. Turn on the transmitter and then the
receiver. Center the aileron trim lever on the transmitter. Remove the servo arm mounting screw and the
servo arm.
Step 3.2
Mount the servo arm back on the servo. Position the
arm to be parallel with the back edge of the wing.
Screw the arm into place with the servo arm mounting
screw supplied with the servo.
Locate the two aileron control rods in the hardware
bag. Ensure the clevises are screwed well onto the
threaded portion of the rod. Rotate and tug aggressively on the clevises and ensure that they are not
loose on the rods.
Tape the ailerons into their neutral position so that
they are even with the trailing edge of the wing and
not pointing either up or down.
Step 3.3
Ensure that the aileron control horns are screwed onto
the threaded aileron control horn bolts and that both
control horns are in approximately the same place on
their respective bolts.
Step 3.4
Connect the aileron servo rods to the aileron control
horns per figure 3B. and 3C.
Step 3.5
Connect the clevis to the servo output arm
Step 3.6
Remove the masking tape holding the ailerons.
Step 3.7
In the case of computer radios couple the servos
together by connecting them to the appropriate
receiver channel. In the case of analog radios couple
the servos together using a Y harness.
Step 3.8
Turn on your radio and activate the ailerons, using the
aileron stick and ensure a smooth full motion can be
achieved.
Step 3.9
With the wing top side up and viewed from the back,
ensure that moving the transmitter aileron stick to the
left raises the left aileron and lowers the right aileron.
Movement of the stick to the left will roll the aircraft to
the left. (Counterclockwise roll of the wing when
viewed from the back ).
Step 3.10
With the wing top side up and viewed from the back,
ensure that moving the transmitter aileron stick to the
right raises the right aileron and lowers the left aileron.
Movement of the stick to the right will roll the aircraft
to the right.(clockwise roll of the wing when viewed
from the back).
