The previous builder of my S1 had crafted the wingtips out of aluminum on an English wheel-- a ton of work, but unfortunately, they were significantly asymmetrical. I have pulled them off and am looking at options. A previous post of Ed's on weight saving tips included using flat wing tips. A friend of mine owns several hobby shops and has a lot of experience with large scale RC models. He said many of their flying wings and acro models with flat tips were greatly improved by adding wingtip plates or "splates". Much more stable in cruise, high AOA and landing. It appears the wingtip plates function as a physical boundary for the vortex that forms a spanwise cylinder around the wing. It would be pretty easy to bolt on various "splate" configurations to test effectiveness. Does anyone have any experience with this on a sonerai? Might it improve high speed stability of the S1 in cruise? I'm leaning toward Hoerner tips for aesthetic reasons, but wanted to get some opinions before I jump in.
