i have a friend that fly's the sukoi120 with a fuji 50 engine , man this is a monster, have had no structure or for that matter any problems, lands absolutely like a baby, he has also just started with the 120 edge, nice plane as good as what is out there. but!!!!you need good hardware and servo's and this is where the bucks lie. i am seriously looking at the edge as the smaller one is so good and as you know seagull/black horse all the same. best
