Mike,
If you want a scale like airplane I would have to second the suggestion that you try the F-15. I have a Top Gun F-15 which I flew as a ducted fan at Cherry Creek and at Chatfield and have now converted it to 12 lb turbine which I hope to test fly this week.

I wouldn't suggest the conversion unless you have a lot of time to devote to it. There are others that would be a good choice but require a bigger engine.

If I can be of help let me know.
