Frequently
Asked Questions
What is Pattern?
Bob Pastorello
Pattern is an R/C activity using aircraft primarily designed for precision aerobatic
maneuvering.
*What types of maneuvers are involved in Pattern?
Generally, maneuvers follow prescribed "schedules" of "classes" which
are voted on and incorporated in the AMA and FAI handbooks with their rules cycles. Many
of the maneuvers emulate full-scale aerobatic competition, and some are specific to the
event.
*What are the "classes" in Pattern?
At the present time, there are 5 classes, designed with increasing complexity and
difficulty of maneuvers. Sportsman, Intermediate Advanced, Masters and FAI. FAI is the class
used in international World Aerobatic Championships.
*How are Pattern airplanes different?
Generally, pattern designs are extremely "stable", meaning that they are built
with inherent ability to "stay where put", meaning that these airplanes are
INHERENTLY designed to have little or no self-induced corrections of attitude.
*How are Pattern Competition events run?
Usually, all five classes will be flown, many times on two flight lines in front of two
sets of judges. Scores are given by each judge for each maneuver, based on a 0- 10 scale,
with difficulty weights built into the scoring system. All maneuvers are performed within
an aerobatic box, defined as 60 degrees left and right of the pilot's position, and 60
degrees elevation. Flight line average distance is recommended to be 150 - 175 meters.
*How is the winner of an event determined?
Each class usually awards plaques, or prizes for each of the first three places, depending
on turnout, funds, etc. The winner of each place is determined by scores within each
round, with the "best" or highest scoring pilot within a class being the
"winner" of that round. All other pilots within the same class have their scores
comparatively ranked against this "best" pilot of the round using a system
called "normalizing".
*Are there specialized equipment needs for Pattern?
Each increasing degree of difficulty class places greater competitive demands on pilot
skills, equipment reliability, and capability of designs. Generally, practically ANY kind
of reasonably-capable aerobatic design will work well in Sportsman, while in the FAI and
Masters classes, designs must be pretty specialized and refined to be capable of the
complex figures.
*What organization "governs" Pattern ?
In the United States, the AMA defines competitive requirements, judging criteria, and
contest administration for events. Other countries have similar governing bodies, but the
international class, FAI, is governed by the participating countries who are members of
the CIAM or Federation Aeronautique Internationale.
*Is there a "SIG" for pattern?
The AMA has designated the National Society for Radio Control Aerobatics to be the
"special interest group", responsible for coordination of national events, rules
changes, and contest organizing/planning.
*How do I get started in Pattern?
If your local field has no one involved, get the AMA rulebook, read it, and then GO FLY!!!
Practice the maneuvers and pay attention to all the judging criteria to try and fly the
perfect "10" on every maneuver in your sequence. Then practice. And practice.
And go to a contest which is listed in the "Focus on Competition" in Model
Aviation, published monthly by the AMA in the United States. And start making connections
with great bunch of highly-skilled radio control pilots....and enjoy the competitive
camaraderie that results....
My Thanks to Bob Pastorello, Masters - NSRCA 199, AMA 46373CD,
for getting this page off to such a great start!

* Do I have to have a "Pattern" airplane to start
with in pattern?
No. Maybe I should say definitely NO. The Sportsman class is intended as a place to
experience a pattern contest. Any model under 55 lbs. may be entered in the
Sportsman class.
In all the classes above Sportsman, the model must be no more than 78.74 (two meters) in wing
span or length. It must weigh no more than 11 lbs. (5 kilograms) without fuel.
* OK, I don't have to have one, but do I "need" a pattern plane to start in
pattern.
Still no. For the maneuvers in the Sportsman class, many sport models with ailerons will
do OK. The main purpose of Sportsman is to attract pilots to pattern, and give them a handy
place to start learning. In Sportsman you will gain experience with the basic maneuvers, and
equally important in pattern, the positioning or centering of maneuvers Most any sport
model with ailerons will do OK, including high wing models. Many pattern pilots would
recommend Models such as the following for Sportsman pattern: UltraSport, Tiger 2 or Tiger
60, Kougar, King Kobra, Four Star 40, 60, or 120, Bingo, etc. Any of the Kaos series. Most
semi scale models of aerobatic designs such as the Extra 300, CAP, Laser, Sukhoi, etc.
Models of this general type that are not warped, and have a strong engine are plenty good
enough to not only participate, but can win the Sportsman class. Of course,
"pattern planes" are also great for Sportsman.
