ameyam,
Your absolutely right,a Manufacture is not going to inform you of faults or short coming of their products and "yes" this board and others like it is a good source for answer you seek. The only reason I directed you to their site ,was your question about the aircraft
3D capabilities,I can't answer your question because I don't fly
3D yet. Again general question about recommend power plant and acrobatic capabilities the manufacture is a good source. Sorry I was unable to help.
Cheers: Rich
