4 star
my second plane was a 4 star 60 with a 91 os 4 stroke, great flying plane, but sadly no longer with us, due to a pushrod failure but that's onother story with my ability to solder effectivley, I have also built a 120 size with a saito 180 very fun plane to fly, better than the edge 540 witha 180
my oppinion
