It seems more and as we progress thru the RC options at some stage the need to go faster develops. For me after a number years in radio controlled soaring, mainly large scale gliders, a group of us have been introduced to Pylon racing. Well the debates about model design is on - thin/thick, symmetrical/cambered, straight trailing edges, high points etc. Does anyone know a good website or where I might go that could enlighten us on the design parameters for very fast RC flight?
