i love gas engines and at 12lbs the yak will fly very well, but at 11lbs its awsome and i think i can get it down to 10.5 with the OS 160. i'm using 1 sevo for the elevators and fromeco battery and reg, no pants(yaks don't wear pants)also have JR 8611's all around. if i used a lighter servos i could save several oz's.
i have a 3W 28cc for sale and a YS 140 sport if any body needs them. both are great engines and almost new.
