Have a Dragon Lady .40 ARC, bought about 8 years ago. The model was well built and came with good instructions. I built it stock out of the box, dont remember about the hardware though. As far as flying, I first had an OS.46fx on it and it was a rocket if I opened it up, as the plane is light[8D]. The next engine for the DL was an OS.40 Surpass, not so much power but great for cruising around and cool sounding[8D]. Even with the Surpass it is not underpowered, just reasonably powered. The plane is gentle with no bad habits, take off and landings are smooth as silk. Just a nice flyer.
