I have one still in the box I got off ebay cheap, the construction seem acceptable. I have no idea how the fly and have not found much on the forums about it. I you do a search you might find something but information on the Christen Eagle was scarce last time I looked, and that plane seems to me to have fallen out of favor with the introduction of the Christen Eagles from GP and SkyShark. Maybe someone else can be more help.
