2017 Challenge

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.

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
Tom Cole
 

 Winners :

First Place: Shannon Little

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
