I have been flying Smaragd's for over three years,...............so they're my favorite. I have now some ten flights on my Eclipse. It flies almost identical to the Smaragd. The main difference is that the Smaragd has a bigger front area and slows down a bit easier. I am planning on competing with my Eclipses this year. My Panacea flew well from its initial flight. Unfortunately it met an early demise.
