Im not sure vinyl will work for what i want to do?

I found a scheme that I really like, I just don't know
if I can pull it off.

I really like the forward swept scheme on the wing,
and the strip on the side should not be to hard. I am
still debating weather to do the yellow on the bottom.

I was also thinking of replacing the purple with blue,
but I cant find a good color chart for ultracote.

I cut a yellow piece out of Monokote, and it layed down
pretty flat with just a pit of soap and water, but I know
if I heat it it will off gas.

As for removing the white.... I really would rather avoid
that at the moment. If I screw up the whole thing I will
strip it and redo it next winter when the twins are older
and I have more time.

I have always built kits, and this is my first ARF ever. That
is why I have no experiance adding trim over covering.

Thanks for the help, and keep the idea's coming
