I think the Puppeteer and the DVII would be the most straight-forward builds. Only slight mods are needed to fit the the Saito 56 4-stroke that I use. The Saito 62 would give a bit more umph in the same size package. Here's an extensive thread with various people's build of the Flair Puppeteer. My build starts on about page 16.

And here's a video of the build of my own Flair Puppeteer:

It is only a "fun-scale" version but you really can deck it out to your heart's content. And it's a proven good flyer (over 10,000 sold) and the kit comes with almost everything your need to build it stock.

Such mods will probably be beyond me.
Such mods were beyond ME before I attempted them. Half the fun of building is learning how to build!
