Well I have about 15 flights on it and so far so good. Still battling with the cg a little bit though. It is a bit too tail heavy for my liking and I have the batteries and ignition in the motor box...I have had to add some lead to the front to get it to balance out and it seems to need a bit more. I have it just under 17lbs and would like to keep it that way so I am not sure what I will do. I am thinking about getting a carbon fiber wing tube to lose some weight and allow for some more lead in the nose. It needs around 4 clicks or so of down elevator for level upright flight which I don't like but it is getting better the more I move the cg forward. It flies extremely stable though and it practically lands itself.
