I wonder if any of you guys out there have any ideas on the subject of what is an appropriate wing loading for a given type of model. I generally fly quarter scale gas powered aerobatic models such as Extras, CAPS, etc. I have heard figures of around 28 ounces per square foot being an acceptable wing loading but find it very hard to achieve if not impossible to achieve with gas powered models, even using lightweight motors. I am wondering if any of you guys have worked out the wing loading of your model. What do you find an acceptable level, as we all know lighter models fly better but at what point in terms of wing loading does a model become too heavy? Any thoughts on this would be appreciated.
