Re: Wright Stuff C

lechassin - Don't add clay ballast to your airplane when you fly it with a half rubber motor to make up for the removal of rubber motor weight. You need to make a half motor stick and use that instead of clay ballast. Say you want to test how your airplane will fly with a 2 gram rubber motor and mak...

Re: Wright Stuff C

You can wind a rubber motor to a given “max” torque, and then back off to a predetermined launch torque that will get your airplane just below the highest obstruction when it has reached its peak altitude. In the indoor free flight community this is called a “no touch” flight which is often preferre...

Re: Wright Stuff C

The quality of the rubber can make a significant difference in the flight times that can be achieved. Rubber used for flying indoor models should be stored in a dark, cool environment. Keep it away from sunshine as UV radiation can adversely affect its ability to store and yield energy. Tan Super Sp...

Re: Wright Stuff C

Brian T gave excellent advice in his post yesterday about how to wind a rubber motor for an indoor duration model airplane. Experts go by the length and weight of a rubber motor, and not its width and weight. The thickness and density of commercial rubber varies along its length. Also, it is not pos...

Re: Wright Stuff C

There are some excellent recommendations on this thread by some very knowledgeable indoor fliers. However, some teams may be obsessing over details rather than focusing on the big picture under the WS 2020 rules. A near perfectly performing WS 2020 airplane that can only circle in one direction is p...

Re: Wright Stuff C

You can build your own rubber stripper. See:

Make sure to click on the View Plans icon.

It is not as good as the rubber stripper sold by Ray Harlan, but it costs almost nothing to build.

Re: Wright Stuff C

I have been involved with WS since 2004 as a coach, event supervisor, and workshop presenter. The WS 2020 rules largely dictate a rubber powered model airplane which is inherently unstable and difficult to trim, and will lead to much student frustration and disappointment. Many students will therefo...

Re: High Ceiling Strategy

As usual, coach Chuck has given an excellent description of the theory and best practice for a particular technique that can be used to maximize flight times of an indoor duration rubber powered stick model, like a Wright Stuff airplane. I would like to add two subtle points regarding practice with ...

Re: 2020 Wright Stuff Parameters

See my previous post describing a Wright Stuff pusher. Here is a link to a video showing parts of two flights of a Wright Stuff pusher: https://www.youtube.com/watch?v=WgkJE-gbudc In the video, the pusher is being flown in a Cat IV fling site (135 feet to the highest flyable height). The model was l...

Re: 2020 Wright Stuff Parameters

The Wright Stuff event has previously awarded a bonus for flying a model with a pusher configuration. I will try to post a picture showing a design used in the 2008 competition. The prop on this pusher model is a stock Ikara prop, installed backwards, so that the rubber motor has to be wound counter...
