You can build a balsa S&T wing to surprising strength. You could even cover it
with MonoKote to make it stronger. The ducted fans are no doubt heavy. You
should find a way to lighten them up some. Maybe even build lighter housings
for them. Seems like a lot of work- you think the plane is worth it?

I don't know of any forums for the monster. Might be good to find one since it's
discontinued and you may need parts for it in the future.
