Started the Right Way

Free flight
airplanes are model airplanes designed and built to fly by themselves,
unassisted by control from the pilots on the ground. Because of this
requirement, free flight models must be designed to be stable under
a variety of aerodynamic conditions. Free flight planes range in size
from tiny scales models of 9" or less in wingspan to giants of the model
world, with wingspans of over 6 feet in length. Whatever their size,
they are designed and built to be as light as possible (what aerodynamic
engineers term "low wing loading."). While the most common building
materials remain balsa wood and light "Japanese" tissue, increasing
use is made of "space-age" materials such as kevlar and carbon.
Because
free flight models do not need to carry radio control receivers and
servos, the designer and builder have a much wider scope of subjects
to model at very small scales. And, they can pick from a wide range
of power.
Hand launch
gliders (HLG) use only arm power. Towline gliders are towed aloft by a
line in kite-like fashion and then set free to glide or soar.
Outdoor rubber-powered and gas-powered models combine a fast climb with
a slow and graceful (hopefully!) soaring flight at the end of the motor
run. Indoor rubber-powered models slowly climb to the top of the ceiling
of a gymnasium and then just as slowly descend with the prop turning all
the time.
Outdoor power models may feature a rocket-like climb with an internal
combustion engine screaming at 25,000+ rpms. The models may be scale models,
resembling a prototype full-scale airplane. Or, they may be designed as
purely functional machines, called duration models, bearing little resemblance
to any full-scale airplane. Explore some of the different kinds of free
flight models.
If you are interested in trying your hand, here is some advice.
1. Try to make contact with free flighters in your area. We are spread
thin, but most major cities have at least a few sportsmen (and women).
If you make contact, show up at flying sessions and contests, even if
you do not have a plane to fly. Most free lfighters are happy to help
and happy to recommend how to get started. Protocol: do not approach someone
who is preparing to fly or flying. Free flighters expend considerable
amounts energy concentrating on doing things to prepare for a flight and
watching a flight.
2. Look in the model magazines for mail-order businesses that carry free
flight kits and supplies. Free flighters run many of these businesses.
They tend to carry quality kits that you will never find in the average
model shop today. A few dollars spent on catalogues will put you ahead
of the game.
3. There are a few local model shops run by owners who know free flight
and carry quality free flight kits and supplies. If one of these shops
is close to you, thank your lucky stars, you hit the jackpot. Buy as much
as you can through this shop, even if you could save a bit by ordering
through mail order. The advice you will get will more than make up the
difference. Sadly for the free flight community, most shops cater to the
R/C community. The owner may be a very competent R/C modeler, but R/C
is not free flight. Also, you might notice that the shop carries a small
line of free flight kits. Some of these will be good (for example Peck
kits), other will only be frustrating unless you know how to modify them
(see Silver Streak modification project.). Some, such as the Guillow Lancer,
are actually good flying kits.
4. Do not start with a scale model and most especially a tiny scale model.
Many hobby stores have "peanut scale" model kits. They are inexpensive
and the fact that they are scale is appealing. But, it is hard for the
beginner to get these models flying. Leave them aside until you have more
experience. Or, build one just to practice handling balsa, but don't expect
it to fly well until you gain some experience.
5. If you have absolutely no experience, buy, build, and fly several AMA
Cubs, also known as Delta Darts. The kits are cheap and Darts can be flown
indoors or outdoors. They will teach many of the basics of adjusting and
flying rubber-powered planes. Bill
Kuhl's Delta Dart site has lots of information about getting started
with this plane. Follow his building program and pay attention to his
excellent explanation of some of the technical details.
6. Buy a book on free flight models. The Ross books are excellent. The
National Free Flight Society and Hanna's Runway (mail order) carry the
Ross books and others.
7. After a few Delta Darts, catapult hand-launched gliders are great place
to continue. The advantage of this class over straight hand-launched gliders
is that you can launch them more precisely with limited experience. Campbell
makes a great models called the "Straight-up." It is easy to build and
fly. Another great kit is the "Scout," offered by Stan Buddenbohm. (Hand-launched
gliders are also fun. Believe it or not, they require careful building,
adjustment, and flying technique. If you buy one try to read as much as
you can on building and flying HLG.) If you don't want to build, there
are at least two foam ready-to-fly models on the market that I have found
to be fun and good fliers. One is the "Zing Wing" by Dare Hobby
Distributors and the other is the "Sling Wing" distributed by
AllSource. I keep one each in the
car for kids to fly who seem interested.
8. P-30 is an excellent place to continue your building if you are interested
in rubber models. The major advantage is that this class of planes uses
a commercial plastic propeller. The Campbell Souper 30 is widely available
and an excellent flyer. I recommend this class because there is always
a P-30 contest at outdoor meets. This is not true of some other "beginners"
kits that are not much easier to build but seldom flown at meets. (Which
does not mean that they are bad flyers or that they are not fun.)
9. If you are interested in towline gliders I highly recommend that you
find someone who knows how to fly them. Your mentor can recommend a kit
and get you started. I have greatly benefited from advice from some really
good towline sportsmen and I am not sure I could have learned the sport
alone.
10. If you are interested in "gas" power, then you should find someone
who can give you some advice.
11. After two are three Delta Darts, there are also several outstanding
indoor models for beginners. The P-18 and P-24 classes offer those with
beginning skills to successfully build and fly indoor models. They use
a plastic prop. Kits are made by Indoor Model Supply and Mace Models.
Planes of the A-6 class are also excellent. There are other good indoor
kits, the Peck ROG is an example. But if you go to a contest you will
probably not see these planes flown.
