I thought this would be a good place to post this, since these conversion motors weigh more than usual, and I'm sure some people here have experience on which planes to put them on.

I am in the process of converting a 30cc Homelite/Ryobi, and from the looks of it it should weight a little under 4lbs when I'm done with it. I got plans from Uncle Willie, http://*****************.com/about36.html, for the 60"-120" Das Ugly Stick. In the description, he has a rule of thumb that works out to a 1.20 size engine for the 120" span. The 30cc is 1.80. What size should I make it? I've only built 1 kit before, and never done one from scratch. I don't think 120" wings would fit in my car, unless I built them to come apart in the middle which I saw someone do on a build thread here, and it seemed to work out pretty well.

Thoughts? Suggestions?

Thanks!
