zolotiyeruki Posted January 26, 2022 Share Posted January 26, 2022 I've been watching the RevelAero posts on Facebook, and have been wondering: Could you make a Long-EZ/Cozy/whatever even lighter if you used molded parts for the wings and canard? I understand the biggest benefit of moldless construction when RAF was selling plans--it makes composite construction accessible to the average Joe, without the need for expensive tooling, or selling complete assemblies, etc. But if you had molds for the wings/winglets/canard, could there be some weight savings to be found, compared to moldless foam core construction? This is just spitballing--I recognize that you'd need to do some proper engineering to determine rib spacing, wing spar design, layup schedule for the skins, etc. But roughly speaking, would you expect to see much of a weight difference? I imagine you'd have less filling and paint on the outside, and less weight on the inside due to the absence of foam, but more weight due to the ribs. And I'm ignoring for now any difference in the time required to use one or the other technique. Quote Link to comment Share on other sites More sharing options...
