The Still Stuka would be a good choice, and the Dolphin is a proven winner (with a Veco 19, which is a tad weaker than a 20FP). I was going to build a Stuka but a local flier had one that was so good I couldn't bring myself to build one and thus suffer by comparison.

I have another one just about ready for paint.
You know the last one was scattered all across the pavement at Whittier Narrows. (I hate it when that happens)
The aft section is sticking out of the wall at Warren Walkers "Man Cave". It makes for an interesting conversation piece.
Build one anyway Brett!! I know you'll love it . With an FP .20 and a 9x4 APC prop, I flew it with .012 lines at 58 ft.
It very much had the feel of a Skyray, but with a little more pop in the corners.
One more thing, I highly recommend a four inch bell crank.
