Nick,

Sinus is in the same category with Lambada. I own a Lambada and I've test flown the Sinus. Neither are really power off cross country machines. In strong conditions, yes, sometimes it works. They are great as very fuel efficient airplanes for trips and sightseeing and for taking up friends and family on soaring demonstration fun flights. The Lambada is a little better performance than the Sinus and the Lambada actually has decent baggage space for taking a spouse on cross country trips. My low time 2008 Lambada is in always-hangared pristine condition and is also on W&W; now at the ridiculously low price of 67,500.
