That would probably work fine. The only thing to make sure is that you have a large enough prop as the spinner is 3.75" in diameter. The ducted fan motors like to turn up. The only other question would be how to orientate the pipe - either down the side of the fuse, or possibly inside. I never held one of the engines up to it, so really wouldn't know.
In reality, this would fly on a standard .61 two stroke, probably around 90-100mph, so anything more would equal speed....
