how will a molded wing tip work on a foam balsa covered wing. The wings tips will be different between the different building techniques.

I agree Marty. The Q40 type molded wings will allow a plane to be faster than a plane with a built up wing. This in turn will allow less nitro or a run a smaller engine. this lighter weight will then be more consistent on the course and in will force more to switch to this and then we are into the who has the most money scenario.
