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.
