Well, I guess I'm the odd man out here. I built a Balsa USA Northstar and it was a nightmare. I saw a guy that had one and thought it looked cool, never saw it fly but he said it was a good flier so I bought one. I found it to be a tough build, and the final product never flew well after countless CG changes and configurations.

The ACE Seamaster, on the other hand is one of the best seaplanes ever! Unfortunately, it's only available in ARF's now days, but get your hands on one and have a ball!
