Now there IS a question about the leadout guide , maybe the rear wing has a bit of diheadral . Intresting anyway . Thinking maybe 4 ft span , 8:1 A.R. , maybee the T T 36'd pull that size o.k.
Tripped over it here :
https://blenderartists.org/t/racing-biplane-concept/562825/9 more pictures & a few notes .
Other pictures look like ailerons are Front wings . rear plain .
Id do it flaps front wing , nothing rear wing , taiplane / elevators about 50 % or 80 % bigger than they look there .
50 in span , 6 in chord maybe . Looks pretty basic to build , approximately as presented .
Found this looking for the canard foreplane / triplane information . Leadouts look like only real annoyance . Perhaps ? .
