I know this is getting a little off the subject, but I have searched for threads on this and couldn't find any and this seems to be a good thread for a question like this...
This may seem like a silly question....but has anyone ever tried installing the prop backward and hovering a Funtana with the tail up and the nose down? Would installing the prop back wards be enough--do I also have to start the engine back wards. Will I need more power because loss of efficiency? Please post pictures if anyone has done this.
