Feel compelled to drop a bomb regarding the bug and the recent threads re extended wingspan to bring down the wingloading. Could we all just take one HUGE step back from the thread and actually review some things Firstly the bug is a great fun machine but lets be fair it aint gona cut it against a mouldy. seleg D great but on an open structure with no whisper of a d box and you aint got anything like SD over 99.9% o the wing !!! there i said it.... realistikly there are better options in regard to construction method and foil choice selected specificly to make the required alowance for the wide variation of foil obtained with the bugs construction . next the thing is NOT a freeflight machine and whatever foil you give it it will invariably have an optimum wing loading to achieve an optimum air speed, ergo when you try to pull up slipery modern foils they perform like C**P since they a are being flown too slow to work. Rc gliders fly in a much bigger flight envelope than minimum sink freeflight huge camber F1A etc designs and need the capacity to punch upwind , not just float downwind. Ive seen many of the aero classes jump on the techniques and knowlage of the freeflight boys. F3J ,F3k etc has especially utilised the whole carbon d-box carbon capped ribs and trailing edge construction step back and even the fully open F1 a designs utilise things like alternate half ribs forward of the spar , additional spars to provide covering support to better APROXIMATE a selected Foil.
