It's *your* choice. I've had 2 Goldberg cubs. The first one was a jinxed plane - all my fault. I ended up with the full-size wing out of it, then built the clipped-wing for my second plane, so I had both to mess with.

The cub (I think any of them) will do whatever you ask of them on minimal power, and will rip around the sky with a clipped-wing and hotter engine. My brother's Goldberg was a clipped-wing on floats with a KB .61...

They are floaters without being 'trainers'. If you stall a Goldberg Cub, it has a pronounced stall (at least at idle), and will fall out of the sky until it regains airspeed. You can fly one just like a trainer - but they fly so much better when you've mastered coordinated turns (using your rudder and ailerons). And the taildragger aspect adds to the fun and skills-to-learn.

Just remember - with scale details come more-intricate repairs. Probably the only thing I didn't like on the Goldberg Cubs was the cowl, and any problems with it were probably my fault. Replace the wood pushrods if you plan on hotting it up.......
