| Learning to fly
with an engine powered model
Learning to fly with an engine-powered model is something
that can at first seem quite a complex affair. However, like
most things in life once you do a little research, things
are often less daunting. The one big difference though is
unlike starting with a HobbyZone plane and teaching yourself,
with an engine powered plane you will need some help from
people with experience to successfully learn to fly.
The very first things to do are to search out your local model
shop and flying club. These maybe nearby to where you live,
or you may have to make a short trip, in any event the trip
will be worth it. For it is from these two facilities that
you will gain a wealth of knowledge, experience and guidance
as to what model and equipment that will serve you the best.
Whether to choose a ready to fly model, or to build a model
from a set of plans your self, what radio control equipment
or suitable engine you will need and any other essential items
you will need to get started.
The classic high-wing trainer
Lets assume for a moment that you have chosen a ready built
high-wing trainer, a two-stroke glow engine, and the radio
control equipment. You will undoubtedly need additional items,
and it is in the area that shopping from your local model
shop will really pay dividends advising you on best choices
and value for money. The amount of help and information you
can gain from your local flying club will amaze you along
probably with the willingness of the membership to advise
and help you while you are getting through the initial learning
stage.
So OK you’ve got your model, joined the local flying
club, joined the British Model Flying Association (BMFA) and
are insured, and at last the great British summer has arrived!
And you’re ready to go flying!
Pre-flight checks
Before your model takes to the air, get a club member to check
it over. He will be looking to see that everything is working
the right way; are the controls working in the right direction,
ie when you move the transmitter stick to the right do the
rudder or ailerons move to the right, when you pull up elevator
do the elevators move upwards, are all the linkages secure,
the batteries fully charged etc. In effect a complete pre-flight
check, just like a full-size plane, you may have seen pilots
walking around their planes before each and every flight.
So with everything in order, or after any corrections have
been made its time to range test your radio. What is a range
test? Well with the radio switched on and the transmitter
aerial partially extended (one section out being the norm)
you should be able to walk at least sixty to seventy paces
away and still have full control of the model. If this is
all in order, fuel up and range test again with the engine
running; there should be no difference in range but if there
is cut the engine and investigate the problem. Under no circumstances
attempt to fly the model until this problem is resolved.
A little help from a co-pilot
Right then, controls working correctly, radio working properly,
satisfactory range test completed, your ready for your fist
flight. At most clubs there are two main ways that a novice
can get to learn to fly, the first method is whereby an experienced
modeller will take the model off and if all is well, stand
beside the you and at sufficient height hand over the transmitter
to you, then with verbal guidance you will take your first
tentative steps on the road to flying your own model round
the sky, don’t be surprised if the instructor takes
the transmitter from you from time to time, he will do this
at the very first signs of a problem, and this is normal,
it could be because the model is flying to far away, to high,
or getting into any other difficulties, once the model is
in a safe attitude he will hand the transmitter back to you,
this is quite normal. Usually the main issues that you will
face are over-control, and disorientation, over-control is
where you move the transmitter sticks to far and the model
flys in an erratic manner, and disorientation occurs when
the model is either to far away or to high and it becomes
difficult to see what way the model is really going, therefore
it becomes impossible to give the correct control inputs to
recover the model to a safe position, however, long before
the model reaches this stage, your instructor will step in,
take control of the transmitter, and usually rescue the model
before handing control back to you.
The buddy box
The second method is very similar to the first in terms of
pre-flight checks, verbal instruction etc, and differs only
in as much as its known as the “buddy box” method.
The buddy box system is favoured by many clubs, and operates
in the following way, the instructor has a compatible radio
system to yours, and the two transmitters are connected by
a hardwire cable, this system allows the instructor to gain
control of your transmitter by simply pressing a button, or
throwing a switch, this instantly hands control of the model
to his master transmitter, and at the same time instantly
and temporarily disables any signal from what in effect, now
becomes the your slave transmitter, as with the previous method,
once the model is in a safe position and attitude the instructor
disables his transmitter, and once again you have control,
this system offers a very smooth and secure method of learning
to fly.
