RE: Succeedor to ShockFlter
Great Planes has also started kicking some new techniques off that will give Ikarus a run for the money. Their new biplane "reflection" is using a new method of attaching the ailerons to the wing. Instead of tape as most foamies use, they've gone to a new carbon fiber/plastic hinge system. Hopefully this will eliminate some of the long standing problems with foam planes. TAPE SUCKS.
As far as anyone dethroning Ikarus....not yet, but the time is coming. They're getting some pretty stiff competition, and its only a matter of time.
