I just read on the Nitroplanes Yak forum about how the new batch of yaks were not glued, over weight and parts did not line up properly. Many guys said they were having problems. Has any one had problems with the SU-26? How does it fly compared to a Yak 54? I am thinking of breaking into giant scale with a Nitroplane if I can confirm good quality and flying (I want to 3D with it too)
