I am just learning pattern flying. I have used an Ultra Sport 60, but want to move up. The Venus II or Focus Sport are the size airplanes that I am looking for. The main problem is that I enjoy building almost as much as flying. I would like to use an OS120AX or the 4 cycle OS120. Both of these seem to work well in this size airplane. Truthfully, I can't afford a YS engine nor the 30% nitro to run it. I do want a kit though, not an ARF. Suggestions???
