RE: Few Sig wonder ??
my twin came out 55 Oz, but has a wingspan of 48 inches. three degrees right thrust on the right engine
was flying great with good engine out perfos, but I crashed it due to finger troubles... after two dozens of flight.
I will rebuild one same dimensions but with two .25
the following pics are why the twin wonder upgrade is on hold (note that on the whip pic you cans see the wing of one more wonder I really love that plane lol)
as soon I am rich enough I dream to jump in the turbine world
