Wasn't the Skipper designed by the same person as the Tomahawk,Who then Ironed out all the Tomahawks flaws. Read somewhere that the original Pa38 was designed with 11 full ribs in the wings and the production model had only 4 full ribs and the rest were only half ribs ,Hence weaker wing and it flexes. The only real problem i find on the Tomahawk is the stupid trim system ,That big spring that bounces around in turb. I did most of my PPL in a Tomahawk dam fine Aircraft.A nice Black example.. katana for me!!!
