Just finished my second complete build, first was Fisher Flying Products Dakota Hawk, second was Mini Max, wanted to start another project while wringing out the Mini Max, so did a lot of research on what plans build u/l might be available, not a lot of choices, the Sportlite 103 seemed to fit the bill as it appeared to be possible to make the weight for u/l, and it actually bore a lot of resemblance to a challenger which has been a success story. However, at 73 years old, maybe I am better served by just getting the mini max straightened out and flying right rather than doing that and building another one and working full time. So, I am offering a very good plans package with manual and prints I bought off e-bay including the builder's build photos which I know from experience are very helpful. I paid $225 and am offering them for $99 with buyer to be responsible for shipping($30-50) If you like building and want a u/l, there are not many choices out there. I can provide more info. Kim Brown
