I went wtith the Funtana 90 over it though....
that is sort of WAY out of the spec of these two. the funtana 90 takes a much larger engine is in general a much different plane...
anyway, the twist is smaller, lighter, cheaper, and you can also get by with a smaller engine in it, whereas a ucd46 with a 46 is going to be a dog. They both are great planes, but for your engine I would recommend the twist.
