New Flying Challenge for the 2021 - 2022
season
Start thinking and building now so you will be ready! :-)
The first challenge proposed by Bryan, Bob, and Esvin on
11/14/21
*** This challenge is for rubber and RC with separate
classes ***
The plane rolls off the ground and at 10’ or greater drops a
bomb
The winner will be closest to the center of the gym floor
in each class
PLANE EXAMPLE:
Bob found a link to an old Sterling A15 Zero plans
that show a belly tank release.
http://freeflightarchive.com/images/plans/sterling_plans/sterling_a15_zero_plan.pdf?type=file
CONSTRUCTION PARAMETERS:
Plane must comply with general rules
A DT timer is allowed
The bomb will have a 4” or longer streamer
attached between the rear fins
Plane + Rubber/battery + Bomb <= 28.34 g
The bomb is 2” long weighing 2.1 g
Floor Setup:
A 10’ PVC pipe will be setup vertical at the center of the
floor, this will make judging easy and give reference to the
center
2021 challenge
We need New Flying Challenges for the 2019
- 2020 season
Start thinking and
building now so you will be ready! :-)

CONSTRUCTION PARAMETERS:
1.
Airplanes may be constructed from published plans,
commercial kits, and/or a personal design.
Kits must not contain any pre-glued joints or pre-covered surfaces.
2.
Any materials except Boron filaments may be used in

exceed 35.0 cm.
The maximum wing chord (straight line distance from leading edge of wing to
trailing edge, parallel to the fuselage) of the wing must be 7.0 cm or
less.
UPDATE 12/25/18 BP
The horizontal stab cannot exceed 60% of the wing area.
5.
The propeller assembly may be built by the
participants or purchased pre-assembled. It may include a propeller, a shaft, a

First challenge is proposed by Bob Schaefer:
Bob and Gene are in the lead
A multiplane consisting of 5 or more wings, (rubber
and electric) classes.
Having a total weight equal to or less than one ounce (~28
grams).
The winners will have the greatest
time aloft.
 
(Sorry, no lighter than air aircraft, helicopters, or
gyrocopters permitted.)
Weight Challenge Status:
Tom & Gene tied at 4 pennies each
Update: Bob
lifted 53.3 grams
Update:
Bryan lifted 84 grams
First 2016 challenge
Build a roll off the ground free
flight rubber and/or electric RC aircraft with a hook preferably close to
the CG to hold added weight. Add weight until you cannot meet the minimum
flight height of 4 feet. Tom has sanctioned all aircraft in this challenge
to exceed maximum weight limits during challenge flights. Tom may define
times for challenge flights.
Record the time above the minimum
flight height. After your best flight, bring the plane to Tom's table where
the aircraft and weights will be weighed and the flight time will be
recorded.
The winners, for FF rubber and for
electric RC, are the aircraft lifting the most load. If there is a tie, the
greatest time aloft decides the winner.
Rules: Apply to both Rubber and
Electric RC aircraft.
1. Max weight including batteries
or rubber and attached hook: One ounce (28.34 grams)
2. Must roll off the ground.
3. Bring your own weights to work
with your hook. (Weights must be removable)
4. Must meet minimum flight height
of 4 feet, during which it will be timed.
5. No lighter than air aircraft,
such as blimps or large helium balloons, allowed.
6. Electric helicopters or quads
(or as many motors you want) must fly upstairs.

All Winners
2011-2012 Competitions
Greg is presenting us with the next
challenge plane of his own design and the
Buzzards once again have gone beyond
themselves and made kits,
which Tom and Pat Cole are packaged.
Bring money this February 13: a
complete kit for $7 (All you add is glue and labor)
Update: If you are
building the canard plane and were wondering how much dihedral you should
have on the wing and canard.
I will answer
this two ways:
1. Place the
wing down flat on the work bench and raise the wing tip 2.5 inches
(I talked to Greg you could increase the dihedral
to 3” if you think that would be better)
2.
Place the center of the wing on the bench and raise each tip 1.25 to
1.5 inches the canard has the same dihedral
I would however only use the 1.25 on each tip
The CG is
8.75 inches from the front of the motor stick
Hope that all
of you are coming along with the build

I
propose this season's
first challenge:
Rubber powered helicopters in line with the Science Olympiad competition.
Guidelines:
Total Mass
>=4g, Power <= 2g, Max rotor diameter 40 cm, Maximum of 3 rotors
Whatever you want we are doing this for fun :-)

Default
Challenge is made from Dart
Kit
Tom has kits for $1.50 if you want something to
start with
He also has plans that you can pick up at the first flying day
See what you can make - Yours could be a bi, tri,
or tetra wing plane;
a helicopter, ultra large, ultra small, built up
fuselage, etc.
In other words, see how creative you can get
This is not for competition… just for fun
