I mostly agree with this list. I was impressed with the quality of my SebArt Sukhoi 30. The quality was better than my three H9 planes and all of my other ARF's. It was also the first time I used all the stock hardware in an ARF. My Ultra Stick 40 also had issues including a lack of glue on the firewall. Luckily, it seperated before I ever flew the plane and it still flies today. I also still have my original H9 trainer.
