I believe the final definition for a canard in the ELG event was very well articulated.
A capacitor powered Wright Stuff event has many potential drawbacks. For one, a team with lots of resources can buy 500 capacitors, all marked with the maximum amount of micro-farads allowed under the rules, and then test them one by one to determine the capacitor with the optimum capacitance. Capacitors have tolerances, i.e. slight variations from their labeled capacitance. Removing the rubber from Wright Stuff eliminates the torque v. turns and prop matching analysis and leaves the event with a "cookie cutter" electric motor, capacitor and prop combination. Do we really want the winner of the Wright Stuff event to be the team with the most expensive miniature brushless DC motor and Lithium Polymer battery combination?
As to bonuses for the Wright Stuff event, those directed toward variations in air frame configuration are the most constructive. For example, bonuses for a smaller wing chord, a canard configuration, a pusher configuration, a twin propeller configuration and so forth, can be very challenging and instructive. Air frame configuration bonuses encourage experimentation and have the greatest potential for students to learn the most about aerodynamics. How about bonuses for the use of a 3-bladed propeller or a four-blade propeller, with the proviso that the blades are of equal size?
With no limit on wing chord, students can determine the sweet spot. In the past, there have been bonuses for pushers and canard airplanes in Wright Stuff. The pusher bonus was very successful as many teams opted for this design at the State level using a great Wright Stuff pusher design by the legendary Cezar Banks. Not as many teams appeared to have elected to gain the canard bonus, but with enough bonus, e.g. 20 - 30% of flight time, students might be encouraged to try that very interesting configuration. Indoor and outdoor rubber powered stick model canard aircraft have been flown successfully for many, many years.
I am against a payload bonus. With wing span, wing chord, and rubber motor limitations, there is little a student can do to improve the load carrying ability of a Wright Stuff airplane. If the goal is to have shorter flights, simply limit the maximum rubber motor size to 1.5 grams, as has been done in the past in the Wright Stuff event. Also, the heavier the model airplane, the more susceptible it is to damage upon a collision because it has to fly faster to stay aloft. Students need to have Wright Stuff airplanes that can survive a lot of test flights.
