The RC hobby is a potentially dangerous hobby that can cause physical
harm and damage to others. Each RC pilot
participates at his own risk. These tips are especially
helpful to new pilots. This
is a lengthy document that you
need to read
more
than once. There is more information here than you
can possibly retain in one sitting. The
content is not to be construed as an all-inclusive instructional
document pertaining to all RC topics. The intention
is to provide the beginner with something to read that hopefully
encourages questions and discussions with
instructors and experience members. No one person can teach
you everything you need to know. The RC hobby
is a fun ongoing learning experience that encourages interaction and
fellowship with fellow hobby enthusiast.
Get involved, ask questions and begin the learning process .
disclaimer: This is not an original article. I
have gathered
this information from several sources and added my own
experiences, mistakes and input.
FIRST STEP
The most important thing you can do is find a flying club in your
area. Go watch them fly. Introduce yourself and
tell them you are interested in taking up the sport. Find
which one is considered to be an expert model builder.
Spend time talking to him. You will find that most modelers are very
friendly and more than happy to give you
plenty of advice. Do this and you will save a lot ot time, aggravation,
money and avoid a lot of mistakes. to find
a club in your area.

RULES
RC is a great hobby that is wonderful fun but it can also be dangerous
if we neglect safety. This means we all
have a mutual responsibility to look out for each other and to help
keep the sport safe for everyone. The rules
of the club where you are flying were put into effect for your safety
and enjoyment. Take this matter very seriously.
ASK FOR HELP AND
TAKE ADVICE
Each time you go to the field you should learn something new
about the hobby. If you aren’t learning it’s because
you aren’t asking, or paying attention. Any question you don’t know the
answer to is a good question. All you have
to do is ask. From time to time we all wonder why someone didn’t tell
us about this or that. Remember, you need
to be patient and assertive in seeking out answers to your questions.
Some of us are more stubborn than others,
which usually is revealed by the number and variety of mistakes we
make. Eventually we learn to swallow our pride
and
listen to the years of experience that is made available free of
charge. We can’t tell you how many times we all have said the
following. “You know what, he/she said was right.” So, once you ask the
question and get a good answer, pay heed to it. It may very well keep
you, or someone else from losing an airplane, damaging property or
becoming injured.
SIMULATOR
TRAINING
Before working
with an instructor, many of us first learned how to fly on a simulator.
Some of us didn’t. Those that learned on a simulator will tell you that
it makes the learning experience more fun and overall less expensive.
Instructors will tell you that money spent on a simulator will pay you
back in spared airplanes. If you can save just one airplane from the
garbage can you have paid for the simulator. Simulator training can be
used day and night regardless of the weather, or wind conditions. The
benefit of using a simulator is stick time, stick time, stick time.
There are several RC simulators on the market. Ask Rob Baker at
Hobbytown,
USA in Mobile, or ask one of the instructors for simulator product
recommendations before you buy anything.
BUYING AN AIRPLANE
, Field Equipment , ect.
Don't
make the mistake I made. I decided I was going to get into RC
Airplanes. So I went to the local hobby store, told the clerk
I
wanted a "good" kit to build. Well, to make a long story short, he sold
me the wrong plane (wrong for me) and the wrong radio
equipment.
A year later I still have not flown that plane.
This is the time to seek out an instructor, or experienced
Flyer for help. Do not buy anything without first talking
to someone that knows what he is talking about. Seek help
from an
expert builder. Each has an opinion on which trainer, engine, receiver,
transmitter and servo selections are the best. So, it’s always good to
compare ideas and suggestions by talking with more than one person. In
the end, you have to make your own decision. After all, it’s your
money. Buying new or used is a matter of preference and
budget.
The important thing is to make sure you are getting good value for your
dollars by asking for help in selecting a good quality product at a
fair market price before you buy. After gaining experience with a
trainer you will want to move up to a more advance second airplane.
Again, this is the time toseek experienced help. You need someone to
guide you who is familiar with your flying skills and hobby preferences
before you select your next airplane. There are different airplanes for
different kinds of flying. A qualified instructor, or experienced
member will be glad to help you select the right second plane for you.
Airplanes
are generally classified as high wing, low wing or bi-plane. All
trainers are high wing because they are much easier and more stable to
fly. So start out with a trainer.
FIELD EQUIPMENT
Selecting
the right field equipment is as important as selecting the right
airplane. Here again your preferences and budget will greatly impact
the direction you take. Here are a few basic tips to get you started.
As you watch the members fly at the club you found, learn to recognize
their equipment and accessories, such as field box, battery, starter,
refueling setup, glow starter and extra glow plugs. It is also
recommended that you get a medium sized fishing tackle box to use as a
toolbox and for storing your extra parts and pieces. Many people use
fishing tackle boxes because the design is perfect for storing volumes
of small things in multiple compartments. You don’t get the same design
and layout with a standard toolbox. Smaller tools and flight line
required tools easily fit in the field box. You will need an assortment
of fuel tubing, wheel collars and spare props. You will also need
packages of various screws, nuts and bolts. You should include but not
limit the following items in your tool kit: Scissors, Exacto knife,
extra # 11blades, tape, small drill and drill bits, small flashlight,
small measuring tape, #64 size rubber bands, thin and thick CA glue,
epoxy, accelerator, Goop, blue thread lock, Dremel tool and
accessories, hex head set for standard and metric, wire cutters, small
crescent wench, small hammer, needle nose pliers, very small to medium
flat head and Philips screw drivers. This is not conclusive, but it’s a
start.
WHERE DO
YOU PURCHASE WHAT YOU NEED?
This is
a good question each of us is confronted with when we get into the
hobby. Do you purchase items from your local hobby store or from an
online discount hobby center?
* Local Hobby
Store - The benefits here are immeasurable, especially if you
don't know exactly what your need, such as an airplane,glue
or a
propeller. I shop at HobbyTown, USA in Mobile and Rob Baker is an
expert in
all phases of RC airplanes. He wants you to succeed in the sport and to
be repeat customer. Likewise, returning faulty tools, equipment and
defective products is no problem. Not that you encounter defective
items often, but when you do, it sure helps to have someone local to
deal with.
* Online - If you know exactly
what you want, you can often save a lot of money by purchasing online,
such as lipo batteries. If you are purchasing from overseas, be
prepared to wait sometimes 3-4 weeks for delivery. And do not count on
customer service.
HAVE EVERYTHING
READY
This is pretty
self-explanatory. Have your stuff ready to go. Nothing ruins a
potentially good flying day than being pestered by the little things
that can go wrong when equipment is not properly maintained, charged,
cleaned, organized and ready.
BATTERIES
Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMH), and
Lithium Polymer (LiPo) cells are currently the most commonly used, but
each needs to be charged, discharged, and stored differently. On top of
that, each model may require a different cell count or battery
configuration as well. To determine what pack configuration you will
need, check the owner’s manual of your particular model for more info.
The battery you will need should be listed in the “Items Needed to
Complete” section of your manual.
NiMH cells have many advantages over their NiCd counterparts. With the
removal of Cadmium from the cell, the NiMH cells were able to fill the
need for industrial and hobby-grade batteries all over the world. NiMH
cell manufacturers were also able to offer significantly higher
capacities in cells approximately the same size and weight of
comparable NiCd cells. NiMH cells have an advantage when it comes to
cell memory too, as they do not develop the same performance issues as
a result of improper discharge care.
Lithium Polymer (LiPo) cells are the newest and most
revolutionary cells to come to market. LiPo cells typically maintain a
more consistent average voltage over the discharge curve when compared
to NiCd or NiMH cells. Add to that the higher nominal voltage of a
single LiPo cell (3.7V versus 1.2V for a typically NiCd or NiMH cell),
making it possible to have an equivelant or even higher total nominal
voltage in a much smaller package. LiPo cells also typically offer very
high capacity for their weight, delivering upwards of twice the
capacity for sometime ½ the weight of comparable performance NiMH cells
and packs. That’s right, with LiPos you can often achieve higher
voltage and power output, with more capacity, in a lighter weight
package.
With all of these benefits, why aren’t LiPo packs more widely used?
With so much energy packed into such a small space, there are some
important safety measures to take when dealing with LiPo cells. A LiPo
cell needs to be carefully monitored during charging as overcharging a
LiPo cell (to beyond 4.2v), or the charging of a physically damaged or
overdischarged cell (discharged to below 3.0v under load) can be a
potential fire hazard.
If you are going to go the LiPo route, use a charger that can
correctly charge them (using a constant current, constant voltage
method of charging as LiPo cells can not be “Peak Charged”), such as
the Vision Peak Ultra (DYN4053) or the E-flite Celectra 1-3 Cell
charger (EFLC3005). Not only must care be taken when charging LiPo
cells, but when discharging them as well. You should never
over-discharge a LiPo pack to below 3.0v per cell under load, and you
must use an ESC programmed to provide the proper low voltage cutoff for
your pack (for example, a 9v cut off for a 3 series LiPo pack). Also,
you should never dead short a LiPo pack, even if only for an instant,
as the large amount of energy stored in the small package can catch
fire quite quickly as a result. While these seem like major deterrents
to using a LiPo battery, these usage guidelines are quickly becoming
well known as they are typically well outlined in the instruction
manuals included with most LiPo packs, ESCs and LiPo chargers. However
with all of their performance benefits, there is little doubt that
lithium polymer battery packs are currently the future of battery
technology for electric powered models.
Discharging
and Storage:
Discharging and storage really go hand in hand. For NiCd
packs, you should completely discharge them, to 0.9v per cell, before
you store them NiMH packs should be stored with roughly a 50% charge in
them for best performance. And before you charge a NiMH pack for the
first time in the day, simply drain the pack completely on a discharger
or in the model and you are then ready to charge the pack for use
throughout the day.
LiPo batteries are completely different when it comes to
discharging and storage. Depending on the output voltage of your pack,
you should only discharge your pack so far. For example, during use, a
7.4V LiPo battery (also known as a “2 series” or “2S” pack) should
never be discharged below 6.0 volts under load (3.0v per cell). For
storage of 2 weeks or more, LiPo packs should be stored at
approximately 3.8v per cell to prevent overdischarge or imbalance from
developing among series cells in the packs due to differing levels of
each cell’s self-discharge rate. In the case of a 2S 7.4v pack, the
pack should always be stored at 7.6v. You should also store your LiPo
batteries in a fireproof container or cabinet and never store your
LiPo, or any other battery for that matter, in the model itself.
Pehaps no other item has quite as much effect and influence on
our hobby as rechargeable batteries do. There are almost as many
different theories and misconceptions out there about rechargeable
batteries as there are individual battery sizes and types. Just
remember that knowledge is key when it comes to batteries, as is
consistent charging, discharging, and storage. Whether you are in the
hobby shop or at the flying field, feel free to ask questions of those
around you who may be more experienced. That is one of the best ways to
learn and grow in the hobby.
There
are now
several different kinds of batteries on the market. Some are newer than
others. Some have been proven with much club experience while others
haven’t been tested with time. You will find that most RC pilots use
Nicad batteries. The recommended method for charging your receiver and
your transmitter battery is to place them on the manufacturers
recommended battery charger the night before you plan to fly. Basically
you are looking for roughly ten to twelve good charging hours. Most
chargers have a charging indicator light, which should light up if you
have a good connection. If you have a charging light and it doesn’t
come on, you aren’t charging your batteries. Certain battery chargers
will shut down after detecting a full charge. Avoid overcharging
batteries which results from letting them stay on a charger for days at
a time. Once the charging cycle has been completed, use a BATTERY
TESTER to check the charge level. Most receiver batteries will peak out
around 5.4 volts with a full charge being 5.2 volts. Check your
batteries again at the field as part of your preflight check.
Note:
Nicad batteries are like water in a bucket with a hole in the bottom.
If you leave them off the charger for several hours they will begin to
lose power even if you are not using them. Always make certain your
batteries are fully charged. It is recommended that you check your
battery charge level after each flight. The receiver battery will
usually drop faster than the transmitter battery. Check the receiver
battery after each flight or at least after every other flight.
Avoid flying with a receiver battery below 4.8 volts. Some pilots stop
flying at 4.9 volts, but no pilots fly below 4.8 volts. You can
purchase a field quick charger. These small charging devices connect to
a 12-volt car battery and can recharge your receiver and transmitter
battery in about forty-five minutes. Not a bad idea for an occasional
quick charge if needed at the field, but not recommended as a common
recharging method. Special note: there are different schools of
thoughtregarding whether or not you should cycle your batteries. It is
the general opinion that Nicad batteries do not need to be cycled
though you certainly can do so. Also, the life of a well maintained
quality name brand battery is approximately three years. Change your
batteries at three-year intervals or less.
FIELD
CHECKIN
If you are using anything other than the new 2.4 ghz
transmitter,don't ever
turn your transmitter on before first signing in at the field
and securing your transmitter channel pin from the
transmitter pin board. If your transmitter channel pin is not
available DO NOT TURN YOUR TRANSMITTER
ON FOR ANY REASON WHILE AT THE FIELD. If
you are not certain you understand this subject ask
any club member for further explanation.
To fly at a sanctioned club field, you must first be a member of the
AMA and then you must join the local club.
PREFLIGHT
CHECKS
Always
check your receiver and transmitter battery charge levels with
a tester before flying the airplane.
