I just got one of the World Models ZERO. I just started to put together.
Looks to be a nice ARF, World Models planes seem to be built very good.
This is the .61Newer Zero with flaps installed,retracts and a 63"in. wing span.
The Kyosho Zero is a .40 size.
Kyosho Warbird kits are built nice too, but I do not care at all for the paper covering they use on them.
Kyosho paper covering peels,warps fast in the sun.
There Zero maybe the only one made with monokote,I don`t know.
Both are about the same price.
