- dancottrell 3y agoIt flies within 0.5-1 wingspan. The subscale has been flying within half a wingspan.
- rektide 3y agoYeah that one of the first things I noticed. Some comments from founder: > Typical flight altitudes are 10-30ft above the wave peaks. The waves are well below us. https://news.ycombinator.com/item?id=36053497 https://news.ycombinator.com/item?id=36053497 And discussing how they are not getting as much WIG effect for that, but still significant savings (Vs what, an airplane? How does that compare versus other marine transport?) > The benefit of ground effects are: - 10-20% range extension (agreed, between 50% and 100% wingspan, which is where seagliders fly, the aerodynamic benefit of ground effect is reduced compared to near surface flight) https://news.ycombinator.com/item?id=36053471 https://news.ycombinator.com/item?id=36053471
