Title: Novel idea; Balsa framework covered with EPP foam plane Post by: rcpilotacro on January 22, 2013, 04:14:34 PM The all new H-King Edge 540T blurs the line between foam and balsa 3D airplanes. Featuring a fully built-up fuselage incorporating the use of balsa framework covered with EPP foam, Edge 540T take a look appears to be a good idea
any thoughts?

Will surely hide the rib edge's impressions showing through the monocote. Harder to repair though...and marginal added weight. Is the petrol that goes in harmful to the foam. Don't know, haven't graduated to gassers yet.

Title: Re: Novel idea; Balsa framework covered with EPP foam plane Post by: saikat on January 22, 2013, 05:03:40 PM just a novelty - no way the epp is going to impart
the torsional stiffness of polyester film. Ideal would be if tissue is used as a final layer on top of the epp. This is why many commercial foam sheets have paper bonded on both sides - it increases the torsional strength substantially.
