We built six of these with fifth and six grade kids in the local Gear-up program. Didn't find any of the problems that are described. Our's also have OS .46 AX's in them. They balanced perfect (upside down) with the battery just behind the former in the wing compartment. All fly perfectly.
That is pretty funny. I guess TSands could ask the fifth and six graders for help. It looks like Tsands needs it. LOL!!!!
