I flew mine for the first time near the end of last summer. It flew great. I experimented and tried to fly it with an OS 60 fp 2 stroke. I didn't feel like I had enough prop diameter. I had a bit of bad luck and decided to wait to try it with a larger 4 stroke that will swing a bigger prop. That should happen in a few days. It's a wonderful building kit - challenging and rewarding.

Here's a pic.
